Cat Diabetes
Treatment Cost UK
Managing cat diabetes costs £80 to £200 per month in the UK in 2026. Insulin costs £30-£60/month, plus syringes, glucose monitoring strips, prescription diet, and regular vet blood tests.
What You Will Pay
Diabetes mellitus affects approximately 1 in 200 cats in the UK, with rates rising alongside feline obesity. The good news is that many cats achieve remission with proper treatment, and modern insulin and monitoring options have made management more affordable than ever. Understanding the cost breakdown helps you budget effectively and make informed decisions about your cat's care.
| Component | Typical Cost | Notes |
|---|---|---|
| Diagnosis (bloods + fructosamine) | £100 – £200 | Blood glucose, fructosamine, full panel |
| Insulin (Caninsulin/ProZinc) monthly | £30 – £60 | Twice-daily injections |
| Insulin syringes (monthly) | £10 – £20 | U-40 or U-100 depending on insulin |
| Glucose monitoring strips | £15 – £30/month | Home monitoring recommended |
| Prescription diabetic diet | £30 – £50/month | High-protein, low-carb formula |
| Glucose curve at vet | £80 – £150 | Full-day monitoring, every 2-4 weeks initially |

Factors That Affect
the Price
Insulin type
Caninsulin (porcine insulin) costs £25-£40 per vial. ProZinc (protamine zinc) costs £40-£60 per vial. ProZinc often provides better regulation in cats but costs more. Your vet will recommend the most appropriate insulin.
Monitoring method
In-clinic glucose curves cost £80-£150 each and may be needed every 2-4 weeks initially. Home monitoring with a glucometer (£20-£40 for the meter, £15-£30/month for strips) is cheaper and less stressful for the cat.
Diabetic remission
Up to 30-50% of cats achieve diabetic remission (no longer needing insulin) with early, aggressive treatment and a strict high-protein, low-carb diet. Remission dramatically reduces long-term costs.
Complications
Diabetic ketoacidosis (DKA) is a life-threatening emergency costing £1,000-£3,000 to treat. Diabetic neuropathy may require additional medication. Good blood sugar control prevents complications.
How to Save Money
Buy insulin with a prescription
Caninsulin and ProZinc are available from online retailers at 20-40% less than in-practice prices. With a £21 prescription, you could save £100-£200 per year on insulin alone.
Monitor glucose at home
A pet glucometer costs £20-£40 and strips cost £15-£30/month. Home monitoring reduces the need for expensive in-clinic glucose curves (£80-£150 each), saving £200-£500+ per year.
Use a high-protein, low-carb diet
Switching to a strict high-protein, low-carb diet (prescription or raw) increases the chance of diabetic remission by up to 50%. Remission eliminates ongoing insulin and monitoring costs entirely.
Act quickly at diagnosis
Early, aggressive treatment gives the best chance of diabetic remission. Starting insulin immediately and switching diet at diagnosis saves money long-term by maximising remission chances.
Would insurance have covered this?
On a typical lifetime policy an owner pays the excess (usually £60–£200) and, on some policies, 10–20% of the rest. Pre-existing conditions are never covered, so the time to compare is before something goes wrong.

Frequently Asked Questions
Ongoing management costs £80-£200 per month. Insulin costs £30-£60/month, syringes £10-£20/month, monitoring strips £15-£30/month, prescription diet £30-£50/month, and vet monitoring visits add further.
Up to 30-50% of newly diagnosed diabetic cats achieve remission with early, aggressive insulin therapy and a strict low-carb diet. In remission, cats no longer need insulin. Regular monitoring is still recommended.
Caninsulin costs £25-£40 per vial (lasts 4-8 weeks). ProZinc costs £40-£60 per vial. Online retailers offer 20-40% savings over in-practice prices. Annual insulin cost is £200-£500 depending on dose.
Yes, most lifetime policies cover diabetes diagnosis, insulin, monitoring, and prescription diet — provided it was not pre-existing. Diabetes claims often exceed £1,500-£2,000 per year, making insurance very valuable.
Your vet or veterinary nurse will teach you. Insulin is injected subcutaneously (under the skin) twice daily, usually at mealtimes. Most owners become comfortable with the process within a few days. It is painless for the cat when done correctly.
