| Symptom | Description | When to Worry |
|---|---|---|
| Excessive Thirst | Drinking much more than usual | Immediately — vet visit needed |
| Frequent Urination | Large clumps in litter box | Within 24 hours |
| Weight Loss | Eating more but losing weight | Within 1 week |
| Weak Hind Legs | Plantigrade stance (walking on hocks) | Vet visit — diabetic neuropathy |
| Poor Coat | Greasy, unkempt fur | At next vet visit |

Path to Remission
Diabetes Management Checklist
| ✓ Do | Inject insulin at same times every 12 hours |
| ✓ Do | Feed low-carb, high-protein wet food (avoid dry) |
| ✓ Do | Monitor blood glucose at home with a glucometer |
| ✓ Do | Track food intake, weight, and water consumption weekly |
| ✓ Do | Keep a log of insulin doses and glucose readings |
| ✗ Avoid | Use human insulin (glargine) without vet approval |
| ✗ Avoid | Skip insulin if your cat seems 'fine' — consistency is critical |
Diabetes in Cats: Signs, Treatment, and the Remission Many Cats Achieve
Feline diabetes is more common than most people realize — and unlike canine diabetes, a significant proportion of cats achieve full remission with the right treatment and diet. Early intervention is the key to the best possible outcome.
This is educational information. Your veterinarian must diagnose and manage your cat's diabetes and determine appropriate insulin dosing.
| Factor | Detail |
|---|---|
| Most Common Type | Type 2 (similar to human T2D) |
| Remission Rate | 25–90% with early treatment + low-carb diet |
| Risk Factors | Obesity, neutered male, age 8+, indoor lifestyle |
| Preferred Diet | High-protein, low-carb canned or raw food |
| Common Insulin | Glargine (Lantus), ProZinc |
| Monitoring | Home glucose curves; fructosamine every 3 months |
Recognizing the Signs
The four classic signs: increased thirst, increased urination (including outside the box), weight loss despite good or increased appetite, and poor coat quality. In advanced cases, diabetic neuropathy causes a distinctive plantigrade stance — the cat walks on its hocks rather than tiptoes. Contact your vet immediately if you notice these signs.
The Role of Diet in Remission
Cats are obligate carnivores with minimal need for dietary carbohydrates. High-carbohydrate dry kibble drives blood glucose spikes in diabetic cats. Switching to canned or raw food with less than 10% of calories from carbohydrates — combined with insulin — dramatically improves the chance of remission. This is one of the most impactful changes an owner can make.
Home Glucose Monitoring
Many vets now encourage owners to monitor blood glucose at home using a human glucometer on a small sample from the cat's ear margin. Home curves reduce stress (stress alone raises glucose in clinic settings) and allow dose adjustments between vet visits. Ask your vet whether home monitoring is appropriate for your cat.
Frequently Asked Questions
Can cats recover from diabetes?
Yes — diabetic remission occurs in an estimated 25–90% of cats treated early with insulin and a low-carbohydrate high-protein diet. Remission means the cat no longer needs insulin, though diet must be maintained and monitoring continues.
What do I feed a diabetic cat?
High-protein, low-carbohydrate canned or raw food is strongly preferred. Dry kibble is very high in carbohydrates and drives blood glucose spikes. The switch to a low-carb diet alone can reduce insulin requirements significantly.
What are the signs of diabetes in cats?
Increased thirst, increased urination, weight loss despite a good or increased appetite, and — in severe cases — hind leg weakness (diabetic neuropathy) where the cat walks on its hocks rather than its toes.
