Signs and Symptoms of Cat Diabetes, and What Treating It Costs

A disease in which the cat's cells stop responding properly to insulin, so glucose stays in the blood instead of feeding the body. This is an emergency and needs a vet now if any of these are true: A cat that has stopped eating and is vomiting, weak, breathing oddly or has breath that smells sweet or of nail-polish remover; Collapse, unresponsiveness, or a cat that cannot lift its head.

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.
   • A cat that has stopped eating and is vomiting, weak, breathing oddly or has breath that smells sweet or of nail-polish remover
   • Collapse, unresponsiveness, or a cat that cannot lift its head
   • Seizures, tremors, staggering or profound weakness in a cat that has already had its insulin
   • A known diabetic cat that will not eat but has been given its usual insulin dose
   • Severe lethargy with dehydration and a recent history of drinking and urinating heavily

   Two different emergencies, and telling them apart matters. Diabetic ketoacidosis is uncontrolled diabetes in which the body burns fat for fuel and floods the blood with ketones; Cornell calls it a medical emergency requiring hospitalisation. The opposite emergency is hypoglycaemia caused by the treatment itself: Cornell lists weakness, lethargy, vomiting, incoordination, seizures and coma, says it can be fatal if untreated, and gives the immediate action — offer the cat its usual food, and if it will not eat voluntarily, rub oral glucose in the form of honey, corn syrup or a dextrose gel onto the gums and go to a veterinarian. Cornell is equally clear on what not to do: never force fingers, food or fluid into the mouth of a convulsing or comatose cat.

2. Same dayGet an appointment today. If your own practice is full, an urgent-care clinic counts.
   • Drinking noticeably more and refilling the litter tray far more often, over days to weeks
   • Weight loss despite eating well, or eating more than usual
   • Walking or standing with the hocks dropped towards the ground (a plantigrade stance)
   • A cat that has become lethargic and unkempt alongside the drinking and weight loss
   • Any of the above in a cat also on steroids for asthma or another condition

   These are the classic signs, and they are worth a same-day call rather than a booked-next-week appointment because untreated diabetes progresses towards ketoacidosis, which is a different order of illness and cost. Cornell describes the plantigrade stance as a rare complication of uncontrolled diabetes — nerve damage in the hind limbs — and notes it is not painful and often resolves with treatment. Steroid treatment is on Cornell's list of the most important risk factors, so a cat on glucocorticoids showing these signs should be checked promptly.

3. Routine — book an appointmentBook in the next few days and keep an eye out for anything on a rung above.
   • An overweight, inactive, middle-aged or older cat with no signs at all
   • A cat over nine years old due a routine examination
   • A newly diagnosed, stable cat due a blood glucose curve
   • A cat in diabetic remission that needs continued monitoring

   This rung is screening and it earns its place. Cornell's most important risk factors are obesity, increasing age, physical inactivity, male sex and the use of glucocorticoids, and obese cats are up to four times more likely to develop diabetes than cats at an ideal weight. The VetCompass study found the odds of diabetes were 5.11 times higher in cats aged nine or over than in cats aged 4.5 to 9. Cornell's monitoring schedule for a stable diabetic is a blood glucose curve every three to four months, because insulin needs change over time.

4. Monitor at homeNo visit needed yet. Watch for anything on a rung above and re-read this page if it appears.
   • A treated cat whose weight, water intake, appetite and demeanour are all normal
   • A cat in remission being fed a low-carbohydrate diet
   • Daily home records of water intake, urine output, appetite, weight and insulin given

   Cornell's home monitoring list is exactly this: activity and demeanour, daily water intake, urine production, appetite, body weight, the amount of insulin or medication given, and possibly blood or urine glucose. One rule sits above all of it — Cornell states that owners who monitor blood glucose at home must not change the insulin dose without discussing it with their veterinarian first. A cat in remission still needs the low-carbohydrate diet and close monitoring, because some will eventually need insulin again.

Two signs bring almost every diabetic cat to a veterinarian: a cat that is losing weight while eating well, and a litter tray that needs changing far more often than it used to. Both are easy to miss in a multi-cat house, and both are usually weeks old by the time anyone counts.

The decision that kills most diabetic cats is made in the first week

The mortality figures for feline diabetes describe a decision, not a disease. The canine disease is a different one and is covered on diabetes in dogs. In a VetCompass study of 1,225,130 cats under UK primary veterinary care, 51.2% of diagnosed cats — 192 of 375 followed — were dead within three years. 93.0% of those deaths were euthanasia. And 19.7% of the euthanised cats were put to sleep within three days of the diagnosis.

Merck arrives at the same place independently, stating that up to 25% of diabetic patients are euthanised on day one of diagnosis, "for reasons that can often be mitigated with education about diabetes and the goals of treatment". Merck lists client communication first among the factors successful treatment depends on — as a treatment finding, not a bedside-manner note.

Set that against Cornell's prognosis: no cure, but a good quality of life with adequate management at home, and with early aggressive treatment many cats enter remission and hold normal blood sugar without insulin. The gap between what is achievable and what happens is mostly a conversation that goes badly in the first week.

That is why this page carries prices. A household deciding in the consulting room whether to treat is making a cost decision, usually without the cost in front of them, and the numbers further down are the ones nobody produces at that moment.

Is my cat diabetic, or just frightened of the vet?

One high blood glucose reading does not diagnose a cat. Cats develop stress hyperglycaemia, and a cat that has been boxed, driven and handled can run a high glucose for no reason other than the last hour of its life.

The test that separates the two is serum fructosamine. It reflects a rough average of blood glucose over the previous fortnight and is not affected by the stress of the visit — Merck's rule is that in stress-induced hyperglycaemia the fructosamine is normal. Cornell's diagnosis rests on persistently elevated glucose in blood and urine together with consistent clinical signs, not on a single number.

Ask for it if your cat is being called diabetic on the strength of one in-clinic sample and no weight loss. It is a cheap test that can prevent a decade of injections, and it is the single most useful thing an owner can request at this stage.

Remission is real in cats, and it has a clock

Cats most commonly have the type II form of the disease, in which the cells stop responding properly to insulin rather than the pancreas failing outright. The pancreas is often still working, which is why remission happens in cats and almost never in dogs.

Cornell's timing rule is specific: a cat that has not entered remission within the first six months after diagnosis will almost certainly need insulin for life. That makes the first six months the part of this disease worth spending money and attention on, rather than the part to economise through.

Remission is not a cure. Cornell's instruction is that cats in remission stay on the low-carbohydrate diet, because some will need insulin again. Merck notes that home glucose monitoring improves glycaemic control and increases the likelihood of remission in cats — one of the few interventions here that is mostly effort rather than money.

Walking on the hocks

A diabetic cat that starts walking with its hocks dropped towards the floor has a plantigrade stance, and it is nerve damage from uncontrolled diabetes rather than an injury. Cornell describes it as a rare complication, notes it is not painful, and says it often resolves with treatment of the diabetes.

It matters because it looks like an orthopaedic problem and gets treated as one. A cat with a strange back-leg posture, weight loss and a heavy litter tray is a blood test, not an x-ray.

The two emergencies point in opposite directions

Diabetic ketoacidosis and hypoglycaemia both put a cat on the floor, and the correct response to each is the opposite of the other.

Ketoacidosis is uncontrolled diabetes: the body burns fat for fuel and floods the blood with ketones. Cornell calls it a medical emergency requiring hospitalisation. Sweet or nail-polish-remover breath, vomiting, weakness and odd breathing in a cat that has been drinking heavily is that picture.

Hypoglycaemia is caused by the treatment. Cornell lists weakness, lethargy, vomiting, incoordination, seizures and coma, says it can be fatal if untreated, and gives the immediate action: offer the cat its usual food, and if it will not eat voluntarily, rub oral glucose — honey, corn syrup or a dextrose gel — onto the gums, then go to a veterinarian. Cornell is equally clear on what not to do: never force fingers, food or fluid into the mouth of a convulsing or comatose cat.

The situation that produces the second emergency is mundane. A diabetic cat that has not eaten but has been given its usual insulin is the most common version, and it is a phone call to the clinic before the injection, not after it.

Can feline diabetes be treated without injections?

Sometimes, and the eligibility is narrower than the marketing suggests. Cornell reports that a class of once-daily oral medication — SGLT2 inhibitors — was approved for feline diabetes in 2023, and that studies show them more than 80% effective at improving blood glucose control in appropriate patients.

The word doing the work is "appropriate". They are approved for newly diagnosed, otherwise healthy cats that have not previously had injectable insulin, because they work by increasing how much glucose the kidneys excrete and depend on the cat still making some of its own insulin. A cat already on insulin, or a sick cat, is not a candidate.

That eligibility window closes fast, which is another argument for being seen early. A cat diagnosed at the drinking-and-weight-loss stage has options a cat diagnosed in ketoacidosis does not.

What the first year costs, and what every year after it costs

Feline diabetes is priced in two numbers and most sources quote only the first. The section below separates them: the first-year total covers diagnosis, the workup, and twelve months of treatment and monitoring, and the recurring annual figure is what it costs for the rest of the cat's life afterwards.

Both matter to the decision in the consulting room, and they point different ways. The first year is the expensive one and the recurring years are the ones a household has to absorb indefinitely — which is precisely the trade the day-three euthanasia statistic is measuring.

Two other bills belong in the picture. Cornell's monitoring schedule for a stable diabetic is a blood glucose curve every three to four months, so the routine examination is a recurring line rather than an annual one. And a cat that will not regulate is often a cat with something else going on: Cornell names urinary tract infection, chronic kidney disease, pancreatitis and hyperthyroidism as the conditions to rule out, and abdominal ultrasound is what finds the ones a glucose curve cannot.

One risk factor is worth acting on before any of this. Cornell names glucocorticoid treatment among the most important risk factors for feline diabetes, and steroids are the mainstay for feline asthma — so a cat on a long steroid course deserves that conversation in advance. The full itemisation, the regional spread and the sourcing behind every figure are on our cat diabetes treatment cost page; the numbers immediately below are the same data, summarised for this decision.

Why diabetes mellitus in cats happens

Insulin resistance (type II diabetes)

Cornell: cats most commonly suffer from the type II form, in which glucose levels are high because the cells do not respond appropriately to insulin rather than because the pancreas has stopped making it. That distinction is why remission is possible in cats and rare in dogs — the pancreas is often still working.

Obesity

Cornell: obese cats are up to four times more likely to develop diabetes than cats at an ideal weight, which is why they name maintaining a healthy weight as the single most important thing an owner can do to reduce the risk. The VetCompass cohort found a median adult bodyweight of 5.9 kg (interquartile range 4.6-7.1) among incident cases.

Age

VetCompass: the mean age of cats diagnosed with diabetes was 11.8 years, and the odds of diabetes were 5.11 times higher (95% CI 4.10-6.24) in cats aged nine or over compared with cats aged 4.5 to 9 years. Cornell lists increasing age among the most important risk factors.

Glucocorticoid treatment

Cornell names the use of steroids to treat other illnesses, such as feline asthma, among the most important risk factors. This is one of the few genuinely modifiable causes in a cat that is already lean, and it is a conversation worth having before a long steroid course rather than after it.

Breed and inactivity

Cornell: physical inactivity and male sex are risk factors, and in some countries Burmese cats appear to be at higher risk, though Cornell notes this may not hold in the United States. The 2025 VetCompass analysis found increased odds in Burmese (OR 2.07) and Burmillas (OR 8.30, 95% CI 2.59-26.62), and reduced odds in Bengals (OR 0.24) and Ragdolls (OR 0.11), all compared with crossbred cats.

How a vet diagnoses diabetes mellitus 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.

Blood glucose and urine glucose

Cornell: the diagnosis rests on persistently elevated glucose in the blood and the urine together with consistent clinical signs. Merck's normal feline blood glucose is 75-120 mg/dL measured after food is withheld. What it costs

Serum fructosamine

The test that stops a stressed cat being called diabetic. Cornell: a single in-clinic blood glucose reading may not be enough, because cats develop stress hyperglycaemia; fructosamine gives a rough average of blood glucose over the previous two weeks and is not affected by the stress of the visit. Merck: in stress-induced hyperglycaemia the fructosamine is normal.

Screening for concurrent disease

Cornell lists urinary tract infection, chronic kidney disease, pancreatitis and hyperthyroidism as the conditions that need ruling out, because they contribute to the same clinical signs and change how the diabetes is managed. Merck adds a drug history, to catch the steroid-induced cases.

Blood glucose curve

Cornell calls this the ideal way to monitor regulation: glucose checked immediately before an insulin injection and then every one to four hours through the day, to confirm the average sits in an acceptable range and that it never drops dangerously low. Needed every few weeks while the dose is being set and every three to four months thereafter even in a stable cat.

Continuous glucose monitoring or home testing

Cornell: a small monitor placed on the skin in the clinic records readings every few minutes for several days up to two weeks. Home testing from an ear vein or paw pad avoids stress hyperglycaemia and gives more accurate results, and Merck notes that studies in both dogs and cats show home monitoring improves glycaemic control and increases the likelihood of remission in cats.

Abdominal ultrasound where a concurrent disease is suspected

For the diabetic cat that will not regulate. Pancreatitis, which Cornell lists among the diseases to rule out, and abdominal neoplasia both cause insulin resistance and neither shows on a glucose curve. What it costs

How diabetes mellitus in cats is treated

Insulin injections

Cornell: injectable insulin is the mainstay and has generally been the standard of care, given under the skin approximately every 12 hours. Merck names insulin detemir and insulin glargine as the most common feline insulins, at a conservative starting dose of 0.25-0.5 U/kg based on estimated ideal body weight and not exceeding 2 U per cat, with reassessment five to seven days later. Cornell's practical warning is about syringes — each insulin type has its own concentration and needs the matching U-100 or U-40 syringe. What insulin injections costs

A low-carbohydrate diet

Cornell: a low-carbohydrate diet has been shown to improve blood sugar regulation in diabetic cats, in wet or dry form, though a wet-food-only diet may be better for many cats. Merck recommends a high-protein, low-carbohydrate diet with canned food preferred over dry. For an overweight cat, slow controlled weight loss under close monitoring is part of the treatment, not a separate project.

Oral SGLT2 inhibitors

Cornell: in 2023 a new class of once-daily oral medication was approved for feline diabetes. SGLT2 inhibitors lower blood glucose by increasing how much is excreted through the kidneys, and Cornell reports studies showing them more than 80% effective at improving blood glucose control in appropriate patients. The eligibility is narrow and matters: they are approved for newly diagnosed, otherwise healthy cats that have not previously had injectable insulin, because they depend on the cat still making some of its own insulin. What oral SGLT2 inhibitors costs

Hospitalisation for ketoacidosis

Cornell: ketoacidosis is a medical emergency and cats diagnosed with it require hospitalisation for ideal management. This is the branch of the disease that turns a manageable annual cost into a large unplanned one, and it is the branch that early treatment is meant to avoid. What hospitalisation for ketoacidosis costs

Owner education, which Merck lists as a treatment

Merck's list of the factors that successful treatment depends on begins with excellent client communication, and gives the reason in the same breath: up to 25% of patients with diabetes are euthanised on day one of diagnosis, for reasons that can often be mitigated with education about diabetes and the goals of treatment. That is a treatment finding, not a bedside-manner note. What owner education, which merck lists as a treatment costs

Outlook and prevention

Cornell: there is no cure, but the prognosis for a good quality of life is good with adequate management at home, and with early aggressive treatment many cats enter diabetic remission and maintain normal blood sugar without insulin. Cornell's timing rule is useful and specific — a cat that has not entered remission within the first six months after diagnosis will almost certainly need lifelong insulin, and cats that do achieve remission should stay on the low-carbohydrate diet because some will need insulin again. Against that, the population picture is sobering: in the VetCompass cohort, 51.2% of cats (192 of 375) were dead within three years of diagnosis, 93.0% of those deaths were euthanasia, and 19.7% of the euthanised cats were put to sleep within three days of the diagnosis. The gap between what is achievable and what happens is mostly a decision made in the first week.

Keep the cat lean and keep it moving — Cornell's own conclusion is that maintaining a healthy weight and encouraging physical activity through daily play is the most important thing an owner can do, because obese cats are up to four times more likely to become diabetic. Feed to a body condition rather than to a bowl. If a cat needs glucocorticoids for asthma or skin disease, discuss the diabetes risk and the lowest effective dose with the veterinarian. And take the annual examination seriously past nine years old, because the odds of diabetes rise five-fold at that age and the earliest signs — a slightly heavier litter tray, a slightly lighter cat — are exactly the ones a household stops noticing.

How common it is: 0.39% annual period prevalence (95% CI 0.37-0.42); 2019 incidence risk 0.14% (95% CI 0.13-0.16) — 1,225,130 cats under UK primary veterinary care in 2019, VetCompass Programme; random sample of 1,053 confirmed cases. Source.

What treating diabetes mellitus in cats costs

Costs for diabetes mellitus in cats run from $56 for routine vet checkup (wellness exam) to $3,600 for cat diabetes treatment. A severe case can run past the top of that range — what treatment adds depends on how bad it gets.

Each block below is one procedure we price in full: the national range, the region-by-region table behind it, and how every row was sourced. Rows marked published come from a real price for that geography; rows marked indexed are the national range scaled by a cited regional cost index, and we label them rather than blending the two.

What the invoice for cat diabetes treatment looks like

Cat Diabetes Treatment is the largest single bill on this page, so this is the one worth reading line by line. Clinics quote a bundled number and itemize afterwards; this is the decomposition.

Does pet insurance cover diabetes mellitus in cats?

Cat Diabetes Treatment is normally covered by a standard accident-and-illness policy. Diabetes is covered by an accident-and-illness policy only where no sign of it was recorded before enrolment or during the waiting period, and it is one of the conditions carriers name explicitly when they restrict cover: Embrace publishes that AKC Pet Insurance allows pets with diabetes onto accident-only cover, while Embrace itself does not exclude them. Because the cost of this condition is a recurring monthly one rather than a single event, the annual deductible is charged against it every policy year for the rest of the cat's life, which changes the arithmetic of choosing a high deductible.

What you would get back: 70-90% of the covered bill after the deductible, charged again each policy year because the condition never resolves into a single claim.

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 diabetes mellitus 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–$3,600 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 diabetes treatment shows which policies pay for it, how long the wait is, and how each one words the pre-existing exclusion.

Common questions

Related conditions and costs

What treating it costs, procedure by procedure

• cat diabetes treatment cost $950–$3,600 — What it costs to diagnose a diabetic cat and keep it regulated for a year, and what it costs every year after that if the cat does not go into remission.
• 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.

Related conditions

• kidney disease in cat symptoms — The kidneys lose function slowly and permanently, and the cruel arithmetic is that they hide it until most of them are gone.
• urinary blockage cat — A group of conditions causing painful, frequent, bloody or unproductive urination in cats.
• worm cat symptoms — 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.
• 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 diarrhea — Loose or watery stool, with or without blood, and the sixth most frequently recorded disorder in dogs in primary practice.
• dog ear infection treatment — Inflammation of the ear canal, almost always with a yeast or bacterial overgrowth on top of it.
• dog pregnancy symptoms — The signs owners read as pregnancy - weight gain, a swollen belly, mammary enlargement, milk, nesting behaviour - are produced just as reliably by a false pregnancy, and there is no home test that tells them apart.
• 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.
• dog eye allergies — A red, weeping, itchy eye is what owners call an eye allergy, and environmental irritants and allergens genuinely are, in Merck's words, common causes of conjunctivitis in all species.
• 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 wound treatment — Cleaning and closing a wound is mostly a timing decision, and the two things owners get wrong are both correctable in the first hour.
• 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.
• yeast infection in dogs — Malassezia pachydermatis is a yeast that lives on normal dog skin and in normal ears.
