Worm Symptoms in Cats: What You See, and What It Costs

Worms in cats are usually silent, and the signs owners are told to look for - a dull coat, a potbelly, vomiting, diarrhoea - are the same signs as a dozen other things. This is an emergency and needs a vet now if any of these are true: Very pale or white gums, weakness, or a kitten that is cold and limp; Black, tarry stool.

Is this an emergency?

Worst first. Find the highest rung that matches what you can actually see, and act on that one — not on the one you hope applies.

  1. Emergency — go nowGo to an emergency vet or the nearest open clinic now. Do not wait for morning.
    • Very pale or white gums, weakness, or a kitten that is cold and limp
    • Black, tarry stool
    • A kitten with a swollen, hard, painful belly that is vomiting repeatedly
    • Repeated vomiting with worms visible in the vomit and a kitten that is deteriorating
    • Collapse or laboured breathing in a kitten with a heavy worm burden

    This rung is almost entirely a kitten problem and it is real. Cornell: hookworms live attached to the intestinal wall and feed on blood, severe infestation causes anaemia from blood loss, the stool often appears black and tarry from digested blood, and if too much blood is lost an affected cat may die without treatment. For roundworms, Cornell says infections are usually relatively benign but that if left untreated they may cause potentially life-threatening anaemia and, in extreme cases, stomach rupture, so infection should be taken seriously and treated aggressively. A pale kitten is an emergency tonight, not a deworming tablet.

  2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
    • Worms seen in the stool or vomit - spaghetti-like, three to five inches, cream-coloured
    • Diarrhoea that has continued more than a day or two, especially in a kitten
    • Vomiting with weight loss or a poor appetite
    • A kitten that is not growing, has a potbelly and a dull coat
    • Any of these in a kitten under twelve weeks

    Cornell's roundworm description is the identification most owners need: adult roundworms are three to five inches long and cream-coloured. But the same signs come from panleukopenia, from a foreign body and from other infections, so a young kitten that is vomiting and losing condition is seen today rather than dewormed on the assumption it is worms. Take a fresh stool sample with you - Cornell notes infection is confirmed by finding parasite eggs on microscopic examination of the stool.

  3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
    • Rice-grain or sesame-seed segments around the tail, in the bedding or in the stool
    • Scooting or excessive licking under the tail
    • A dull coat, mucousy stool, or intermittently soft stool in an adult cat
    • A newly adopted, stray or outdoor-access cat
    • A cat that hunts, or lives with fleas

    Tapeworm segments are the thing owners actually see, and Cornell says finding them can alarm owners but that tapeworm infections rarely cause significant disease in cats. The important part is what they imply: cats usually become infected by swallowing an infected flea while grooming or by eating an infected rodent, so a tapeworm is a flea problem or a hunting problem, and treating the worm without treating the fleas guarantees a repeat. Cornell also warns that microscopic examination of faeces may miss tapeworms entirely, because eggs only pass grouped inside the segments.

  4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
    • An indoor adult cat on year-round parasite control with no signs
    • A queen due to be bred, or a litter of kittens on a deworming schedule
    • A household with young children and an outdoor cat

    Monitoring here means testing on a schedule rather than watching for symptoms, because Cornell notes the majority of Giardia-infected cats show no signs at all, and roundworm infections are frequently silent. Cornell's specific preventive advice for queens is to treat before breeding, which reduces the chance the parasite reaches the kittens; kittens can pick up Toxocara cati larvae through the queen's milk and be infected soon after birth.

Most cats with worms look well. The symptom list every article prints — dull coat, potbelly, vomiting, diarrhoea — describes a dozen other diseases just as accurately, which is why identification matters more than symptom-spotting.

What you can actually see

Cornell's descriptions are specific enough to use. Tapeworm segments are flat, about a quarter of an inch long, and appear near the tail, in bedding or in the stool: they look like grains of rice when fresh and sesame seeds when dry.

Adult roundworms are three to five inches long and cream-coloured, and look like spaghetti. They turn up in vomit or in stool, and seeing one is the most common reason an owner books this appointment.

Hookworms you will not see at all. Cornell describes them as slender thread-like worms under half an inch long, attached to the intestinal wall, usually not visible in faeces because of their size — and capable of living as long as the cat does.

What you see also tells you nothing about severity in an adult cat. Cornell says tapeworm infections rarely cause significant disease in cats, and that finding the segments alarms owners more than it should. The information in a tapeworm is about the household, not the cat.

A tapeworm is a flea problem wearing a disguise

Cats get tapeworms by swallowing an infected flea while grooming, or by eating an infected rodent. Both are Cornell's routes, and neither is fixed by a dewormer.

So the tapeworm is a symptom of the flea, and treating the worm without treating the fleas guarantees the same appointment in a few months. Cornell is explicit that modern treatments work well but reinfection is common, and that controlling flea and rodent populations is what reduces the risk.

The same logic runs through the whole record. Every route of infection here goes through prey, fleas, or another cat's faeces — which is why Cornell's control list is daily faeces removal, disinfecting the litter tray, avoiding overcrowding, avoiding raw meat diets, and controlling fleas, ticks and rodents. The unglamorous half of that list is free.

How common are worms in cats, really?

The two figures in circulation differ by an order of magnitude, and both are defensible. Cornell puts roundworms at 25% to 75% of cats and gastrointestinal parasitism as high as 45% in some populations. A 2023 US laboratory review of 15,395 faecal examinations on client-owned cats found 13.52% positive for any parasite, with Giardia at 4.82%, Toxocara cati at 4.75%, Cystoisospora at 3.40%, Ancylostoma at 0.61% and Dipylidium caninum at 0.39%.

The gap is a sampling difference rather than an error. Cornell's higher figures come from shelter, stray and free-roaming cats; the laboratory dataset is owned cats whose vets submitted a sample, most of them already on parasite control. Quoting the shelter number to the owner of an indoor cat would be as misleading as quoting the laboratory number to a rescue.

Two caveats belong with the newer figure, and almost nobody attaches them. It was conducted and authored by employees of a commercial diagnostic and parasiticide company, and it counts test results rather than cats — a cat tested twice appears twice, and a cat never tested does not appear at all. We still use it, because it is the largest contemporary US dataset published, and because Cornell's own page carries no US denominator.

A clear faecal test does not clear a tapeworm

Faecal flotation is the standard test and it has a specific blind spot. Cornell states that microscopic examination of faeces may miss tapeworms entirely, because the eggs pass grouped inside the segments rather than free in the stool.

That means a negative faecal in a cat with rice-grain segments around its tail is a false negative, and the segments win. Say what you saw, describe it in Cornell's terms, and do not let a clear test end the conversation.

Giardia has the opposite problem. Cornell notes cysts are not shed continuously, so several samples may be needed, and diagnosis may rest on antigen or DNA testing rather than microscopy. The majority of Giardia-infected cats show no signs at all while remaining a source of infection to other cats.

Sending a sample is worth doing well. The same faecal test finds the feline lungworm behind some cases of chronic coughing in cats, and the equivalent workup in dogs sits on our page on dog diarrhoea.

The kitten version is the dangerous one

Almost everything on the emergency rung of this page is a kitten. Cornell: hookworms attach to the intestinal wall and feed on blood, severe infestation causes anaemia from blood loss, the stool often appears black and tarry from digested blood, and if too much blood is lost an affected cat may die without treatment.

Roundworms get there by a different route. Cornell calls infections usually relatively benign, then states that untreated they may cause potentially life-threatening anaemia and, in extreme cases, stomach rupture — which is why a kitten with a rigid, painful abdomen is imaged rather than dewormed.

Pale or white gums in a kitten is an emergency tonight, not a dewormer tomorrow. The order of treatment is warming, fluids and sometimes a transfusion first, and the anti-parasitic drug after the kitten is stable.

Kittens also start infected. Cornell notes Toxocara cati larvae can pass in the queen's milk, so kittens can be infected soon after birth — which is why the deworming schedule is a schedule rather than a response to symptoms, and why Cornell advises treating queens before breeding.

Can I catch worms from my cat?

Yes, rarely, and the consequences can be serious. Cornell notes that Toxocara larvae migrating through human tissue cause visceral and ocular larva migrans, that this is rare but can be serious especially in young children, and that hookworm larvae penetrating human skin cause cutaneous larva migrans.

This is the reason to treat a cat that has no symptoms at all, and it is the strongest argument on the page. It is also the reason for the least glamorous instruction: clean the litter tray daily. Cornell notes Toxoplasma oocysts take approximately one to five days to become infective after being shed, so daily removal takes them out before they matter.

Wash hands after litter trays and after gardening, and cover sandpits. Those three habits do more for the human members of the household than any product sold for this problem.

What this costs, and what we do not price

Be clear about the shape of the bill: in almost every case this condition costs a consultation, a faecal test and a course of prescription medication, and we publish a researched price record for only the first of those three. We are not going to estimate the other two.

What the section below prices honestly is the consultation where the cat is examined and the sample is taken, the emergency visit for the anaemic or obstructed kitten, and abdominal ultrasound for the kitten whose belly suggests something worse than worms. Those are the three real branches, and the second and third are the ones worth insuring against.

The recurring cost is the one to plan for. Cornell describes reinfection as relatively common after successful roundworm treatment, common for tapeworm, and difficult to eliminate for Giardia in a multi-cat home — so the honest budget is year-round parasite and flea control for every animal in the house, plus the occasional test, rather than one course of tablets.

Why intestinal worms in cats happens

Roundworms - Toxocara cati and Toxascaris leonina
Cornell: the most common intestinal parasite of cats, affecting 25% to 75% of cats with higher rates in kittens. Cats acquire Toxocara cati by eating eggs or rodents carrying larvae in their tissues, and kittens can ingest larvae in the queen's milk. Toxascaris leonina cannot cross the placenta or pass in milk, so cats under two months rarely carry it. Cornell also notes reinfection after successful treatment is relatively common.
Hookworms - Ancylostoma and Uncinaria
Cornell: slender thread-like worms less than half an inch long, attached to the intestinal wall and feeding on blood, usually not visible in the faeces because of their size, and capable of living as long as the cat does. Adult cats are usually infected by larvae penetrating the skin or being swallowed. Less common than roundworms, with prevalence varying considerably by geography in North America.
Tapeworms
Cornell: the adult lives in the small intestine with its head embedded in the lining, and mature egg-filled segments break off and pass in the faeces. Cats become infected by swallowing infected fleas while grooming, or by eating infected rodents; fleas and rodents pick up the eggs from the environment. Cornell notes modern treatments work well but reinfection is common, so flea and rodent control is the actual cure.
Protozoa - Isospora, Giardia and Toxoplasma
Cornell: virtually all cats become infected with Isospora felis at some point, usually harmlessly in adults but capable of destroying the intestinal lining and causing mucousy diarrhoea in kittens. Giardiasis occurs in fewer than 5% of cats, is commoner in multi-cat households and in cats under a year, and most infected cats show no signs while remaining a source of infection to others. Toxoplasma rarely causes disease in cats but is the reason litter trays are cleaned daily.
Hunting, fleas and crowding
Every route above runs through one of three things: prey, fleas or other cats' faeces. Cornell's parasite-control list is built on exactly that - daily removal of faeces, washing the litter box with a disinfectant such as diluted household bleach, avoiding overcrowding, avoiding raw meat diets, and controlling intermediate hosts including fleas, ticks and rodents.

How a vet diagnoses intestinal worms in cats

Not every test below is run on every animal. Which ones are depends on what the examination finds, and each one is priced in the cost section further down.

Physical examination with weight and body condition
Establishes whether this is a well cat with an incidental finding or a kitten in trouble - gum colour for anaemia, abdominal palpation, hydration and growth against age. It is also where the flea check happens, which decides whether a tapeworm will come back. What it costs
Faecal flotation and microscopy
Cornell: infection is confirmed by finding parasite eggs on microscopic examination of the stool. Its limitation is stated by Cornell too - it may not reveal tapeworms, because their eggs pass grouped inside segments rather than free in the faeces, so a negative faecal does not exclude tapeworm in a cat with visible segments.
Giardia antigen or PCR testing
Cornell: diagnosis depends on finding cysts microscopically or on identifying Giardia DNA or antigen, and several samples may be needed because cysts are not shed continuously. In the largest recent US dataset, Giardia was the single most frequently detected parasite in cats.
Blood count
For the pale or collapsed kitten. It quantifies the anaemia that Cornell says can kill a hookworm-infected cat, and it decides whether the kitten needs a transfusion before it needs a dewormer.
Abdominal ultrasound
For the vomiting, potbellied kitten where the question is whether the abdomen contains a worm burden, a foreign body, an intussusception or something else. Cornell's extreme roundworm outcome - stomach rupture - is why a kitten with a rigid painful abdomen gets imaged rather than dewormed. What it costs

How intestinal worms in cats is treated

Emergency care for the anaemic or obstructed kitten
Warming, fluids, and transfusion where the blood loss is severe, before any anti-parasitic drug is given. Cornell's warning that a hookworm-infected cat may die without treatment if too much blood is lost is the reason this line comes first. What emergency care for the anaemic or obstructed kitten costs
Prescription deworming, matched to the parasite
Cornell: treatment of gastrointestinal parasites often requires medication prescribed by a veterinarian, and the directions must be followed carefully. Matching matters - the drugs that clear roundworms and hookworms do not clear tapeworms, and Cornell notes that with Giardia, effective medications exist but resistance is common and clearing infection from a household of cats can be difficult. What prescription deworming, matched to the parasite costs
Treating every animal in the house
Cornell describes Giardia spreading between littermates and chronic carrier cats, and coccidia flourishing in crowded environments. Treating one cat in a multi-cat household and not the others is how these infections persist for months.
Flea control, which is the tapeworm treatment
Cornell: cats usually become infected with tapeworms by ingesting infected fleas while grooming or by eating infected rodents, and controlling flea and rodent populations reduces the risk. A dewormer clears today's tapeworm; the flea preventive is what stops the next one.
Sanitation
Cornell's list, which is free: daily removal of faeces, washing the litter box regularly with a disinfectant such as diluted household bleach, avoiding overcrowded conditions, avoiding diets with raw meat, and controlling fleas, ticks and rodents. Cornell adds the Toxoplasma detail that makes daily cleaning matter specifically - oocysts take approximately one to five days to become infective after being shed.
Imaging or surgery for the rare severe case
Reserved for the kitten whose abdomen suggests obstruction or rupture rather than parasitism alone. It is uncommon, and it is the reason this record's cost join reaches beyond a dewormer. What imaging or surgery for the rare severe case costs

Outlook and prevention

Excellent for almost every cat treated. Cornell describes roundworm infections as usually relatively benign, tapeworm infections as rarely causing significant disease, and hookworms as easily diagnosed and treated - and modern anti-parasitic drugs are highly effective. Two things change that. The first is severity in a kitten, where Cornell's outcomes are life-threatening anaemia from either roundworms or hookworms and, in extreme cases, stomach rupture from roundworms. The second is reinfection, which Cornell says is relatively common after successful treatment for roundworms, common for tapeworms, and difficult to eliminate for Giardia in a multi-cat home. The honest expectation is that treatment works and that without changing hunting, fleas and litter hygiene, it will be needed again.

Year-round broad-spectrum parasite control prescribed for the cat's lifestyle, plus year-round flea control on every animal in the house, which is what actually prevents tapeworm. Cornell's sanitation list is the rest of it: remove faeces daily, disinfect the litter tray, avoid overcrowding, avoid raw meat diets, and control rodents. Treat queens before breeding, since Cornell notes this reduces the chance the parasite reaches the kittens, and follow the kitten deworming schedule rather than waiting for signs. Wash hands after litter trays and after gardening - Cornell notes Toxocara larvae migrating through human tissue cause visceral and ocular larva migrans, rare but serious especially in young children, and that hookworm larvae penetrating human skin cause cutaneous larva migrans. Cover sandpits.

Does pet insurance cover intestinal worms in cats?

Cat Ultrasound is normally covered by a standard accident-and-illness policy. Imaging ordered to investigate a covered illness is reimbursable under a standard accident-and-illness policy, and carriers do not price or treat feline diagnostics differently from canine ones. Embrace lists diagnostic testing for covered illnesses among what it pays for. The scan inherits the status of the condition it is investigating: a cat already showing signs of kidney disease or weight loss before enrolment will find both the illness and the ultrasound that diagnosed it excluded as pre-existing. Screening scans in a well cat are preventive care and are not covered.

What you would get back: 70-90% of the covered bill after the annual deductible, following the coverage status of the underlying condition.

The catch, and it is the one that matters here: every US carrier excludes pre-existing conditions. If your animal has already been seen for intestinal worms in cats — or for signs a vet later links to it — a policy bought today will not pay for this episode. Cover is something you buy before the diagnosis, which is why the $56–$880 above is worth knowing while your pet is still well.

Waiting periods, and what each carrier counts as pre-existing, differ enough that the only useful answer is a side-by-side: our pet insurance comparison for cat ultrasound shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.

Treat it as an emergency if any of these are true: Very pale or white gums, weakness, or a kitten that is cold and limp; Black, tarry stool; A kitten with a swollen, hard, painful belly that is vomiting repeatedly; Repeated vomiting with worms visible in the vomit and a kitten that is deteriorating; Collapse or laboured breathing in a kitten with a heavy worm burden. This rung is almost entirely a kitten problem and it is real. Cornell: hookworms live attached to the intestinal wall and feed on blood, severe infestation causes anaemia from blood loss, the stool often appears black and tarry from digested blood, and if too much blood is lost an affected cat may die without treatment. For roundworms, Cornell says infections are usually relatively benign but that if left untreated they may cause potentially life-threatening anaemia and, in extreme cases, stomach rupture, so infection should be taken seriously and treated aggressively. A pale kitten is an emergency tonight, not a deworming tablet.

How much does it cost to treat intestinal worms in cats?

Costs for intestinal worms in cats run from $56 for routine vet checkup (wellness exam) to $880 for cat ultrasound. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.

How is intestinal worms in cats diagnosed?

Physical examination with weight and body condition: Establishes whether this is a well cat with an incidental finding or a kitten in trouble - gum colour for anaemia, abdominal palpation, hydration and growth against age. It is also where the flea check happens, which decides whether a tapeworm will come back. Faecal flotation and microscopy: Cornell: infection is confirmed by finding parasite eggs on microscopic examination of the stool. Its limitation is stated by Cornell too - it may not reveal tapeworms, because their eggs pass grouped inside segments rather than free in the faeces, so a negative faecal does not exclude tapeworm in a cat with visible segments. Giardia antigen or PCR testing: Cornell: diagnosis depends on finding cysts microscopically or on identifying Giardia DNA or antigen, and several samples may be needed because cysts are not shed continuously. In the largest recent US dataset, Giardia was the single most frequently detected parasite in cats. Blood count: For the pale or collapsed kitten. It quantifies the anaemia that Cornell says can kill a hookworm-infected cat, and it decides whether the kitten needs a transfusion before it needs a dewormer. Abdominal ultrasound: For the vomiting, potbellied kitten where the question is whether the abdomen contains a worm burden, a foreign body, an intussusception or something else. Cornell's extreme roundworm outcome - stomach rupture - is why a kitten with a rigid painful abdomen gets imaged rather than dewormed.

Does pet insurance cover intestinal worms in cats?

Cat Ultrasound is normally covered by an accident-and-illness policy taken out before the signs started. Imaging ordered to investigate a covered illness is reimbursable under a standard accident-and-illness policy, and carriers do not price or treat feline diagnostics differently from canine ones. Embrace lists diagnostic testing for covered illnesses among what it pays for. The scan inherits the status of the condition it is investigating: a cat already showing signs of kidney disease or weight loss before enrolment will find both the illness and the ultrasound that diagnosed it excluded as pre-existing. Screening scans in a well cat are preventive care and are not covered.

What is the outlook for a pet with intestinal worms in cats?

Excellent for almost every cat treated. Cornell describes roundworm infections as usually relatively benign, tapeworm infections as rarely causing significant disease, and hookworms as easily diagnosed and treated - and modern anti-parasitic drugs are highly effective. Two things change that. The first is severity in a kitten, where Cornell's outcomes are life-threatening anaemia from either roundworms or hookworms and, in extreme cases, stomach rupture from roundworms. The second is reinfection, which Cornell says is relatively common after successful treatment for roundworms, common for tapeworms, and difficult to eliminate for Giardia in a multi-cat home. The honest expectation is that treatment works and that without changing hunting, fleas and litter hygiene, it will be needed again.

Can intestinal worms in cats be prevented?

Year-round broad-spectrum parasite control prescribed for the cat's lifestyle, plus year-round flea control on every animal in the house, which is what actually prevents tapeworm. Cornell's sanitation list is the rest of it: remove faeces daily, disinfect the litter tray, avoid overcrowding, avoid raw meat diets, and control rodents. Treat queens before breeding, since Cornell notes this reduces the chance the parasite reaches the kittens, and follow the kitten deworming schedule rather than waiting for signs. Wash hands after litter trays and after gardening - Cornell notes Toxocara larvae migrating through human tissue cause visceral and ocular larva migrans, rare but serious especially in young children, and that hookworm larvae penetrating human skin cause cutaneous larva migrans. Cover sandpits.

What should I know about intestinal worms in cats?

Worms in cats are usually silent, and the signs owners are told to look for - a dull coat, a potbelly, vomiting, diarrhoea - are the same signs as a dozen other things. Costs for intestinal worms in cats run from $56 for routine vet checkup (wellness exam) to $880 for cat ultrasound. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.

How common are worms in cats, really?

The two figures in circulation differ by an order of magnitude, and both are defensible. Cornell puts roundworms at 25% to 75% of cats and gastrointestinal parasitism as high as 45% in some populations. A 2023 US laboratory review of 15,395 faecal examinations on client-owned cats found 13.52% positive for any parasite, with Giardia at 4.82%, Toxocara cati at 4.75%, Cystoisospora at 3.40%, Ancylostoma at 0.61% and Dipylidium caninum at 0.39%.

Can I catch worms from my cat?

Yes, rarely, and the consequences can be serious. Cornell notes that Toxocara larvae migrating through human tissue cause visceral and ocular larva migrans, that this is rare but can be serious especially in young children, and that hookworm larvae penetrating human skin cause cutaneous larva migrans.

What treating it costs, procedure by procedure

  • routine vet checkup (wellness exam) cost $56–$130 The annual physical examination a healthy dog or cat gets - vitals, ears, eyes, mouth, coat and skin - priced as the exam fee alone, before any test or vaccine is added to the bill.
  • veterinary urgent care visit cost $85–$150 A same-day visit for a problem that cannot wait for an appointment but is not life-threatening, priced between a routine exam and an emergency-room exam at every clinic that publishes all three.
  • cat ultrasound cost $383–$880 An ultrasound scan for a cat, most often a full abdominal study, sometimes with sedation and an ultrasound-guided sample taken at the same time.

  • urinary blockage cat A group of conditions causing painful, frequent, bloody or unproductive urination in cats.
  • why is my cat meowing so much Excessive meowing is a sign, not a disease, and it is the sign this dataset can be most useful about — because its differentials range from a cat that has learned meowing produces breakfast to a male cat that cannot pass urine and will die within about two days without treatment.
  • cat coughing A cough in a cat is a lower-airway problem until proved otherwise, and the commonest cause is asthma - an allergic narrowing of the small airways that Cornell puts at 1 to 5% of cats.
  • dog dementia treatment An age-related degenerative brain disease that Cornell describes as causing deterioration similar to Alzheimer's disease in people, with beta-amyloid accumulating and neurons dying.
  • dog colitis medication Inflammation of the colon, which shows up as small, frequent, urgent stools carrying mucus and often fresh red blood, with straining.
  • dog coughing A cough is a sign, not a diagnosis, and the same dry hack can come from an infection that clears itself in two weeks or from a failing heart valve.
  • dehydrated dog treatment Dehydration is not a disease, it is the measurable consequence of one, and the numbers behind it are published rather than guessed.
  • dog diabetic symptoms The pancreas stops making enough insulin, so glucose stays in the blood instead of feeding the cells, spills into the urine and drags water with it.

  • dog ear infection treatment Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.

  • dog UTI symptoms A bacterial infection of the bladder, usually Escherichia coli travelling up the urethra from the perineum.
  • dog vomiting and diarrhea Sudden vomiting, usually with diarrhoea, from an inflamed stomach and intestine.
  • dog vomiting blood Blood in a dog's vomit - fresh red, dark clots, or the brown grit that looks like coffee grounds because the stomach has already digested it.

  • hip dysplasia in dogs An inherited malformation in which the hip joint is too loose, so the ball grinds in the socket and arthritis follows.
  • ivdd in dogs A disc between the vertebrae ruptures or bulges and presses on the spinal cord, causing pain, wobbliness or paralysis.
  • kennel cough in dogs A contagious inflammation of the windpipe and airways caused by a mix of viruses and bacteria, not by one organism.
  • dog limping Limping means something painful is interfering with the normal use of a limb, and Cornell's framing is that it deserves veterinary attention rather than a wait-and-see.
  • parvo in dogs A virus that destroys the lining of a puppy's intestine and the bone marrow that makes its white blood cells, producing vomiting and bloody diarrhoea that can kill in days.
  • dog seizures A burst of abnormal electrical activity in the brain, which in its classic form drops the dog on its side with stiff, paddling limbs, frothing, loss of consciousness and often loss of bladder and bowel control.
  • staph infection in puppies Crusty pustules on a puppy's hairless belly and groin, caused by the dog's own resident bacterium overgrowing.

  • dog skin yeast infection Malassezia yeast lives on normal dog skin and only causes disease when something changes the skin it lives on.
  • dog vomiting yellow Yellow vomit is bile that has refluxed from the duodenum back into an empty stomach, and it is a description rather than a diagnosis.
  • cat teeth disease Three overlapping diseases, not one: gingivitis, which is reversible; periodontitis, which is not; and tooth resorption, in which the tooth dissolves from the inside out and which Cornell calls the most common cause of tooth loss in cats.
  • symptoms of blocked anal glands in dogs Two small scent sacs sit either side of the anus and normally empty when a dog passes a firm stool.
  • dog skin allergies A lifelong immune reaction to ordinary environmental substances - pollens, moulds, dust mites, dander - that shows up as itching rather than sneezing.
  • worms in dogs Four different worms with four different stories, grouped together only because they all live in a dog's gut.
  • ringworm in dogs Ringworm is a fungal infection of the hair and the surface of the skin, and the name is the first thing that misleads.
