Feline Diabetic Dangers

Feline diabetes is a serious but manageable condition. With the right treatment and monitoring, many diabetic cats can go into remission - meaning they no longer need insulin injections. But getting there requires early diagnosis and consistent management.

Here is what cat owners need to know.

What causes diabetes in cats?

Most cats develop Type 2 diabetes, which is closely linked to obesity and a diet high in carbohydrates. Unlike dogs, who more commonly develop Type 1 diabetes, cats often develop insulin resistance - the body produces insulin but the cells stop responding to it effectively. The pancreas compensates by producing more insulin until it eventually cannot keep up.

Risk factors include obesity, a sedentary indoor lifestyle, male sex, older age, and prolonged use of corticosteroids.

What are the signs of diabetes in cats?

The classic signs are the three polys - polyuria (increased urination), polydipsia (increased thirst), and polyphagia (increased appetite) - accompanied by weight loss despite eating well. Many owners notice that the litter tray needs changing more frequently, or that their cat is drinking from unusual sources.

As diabetes progresses, cats can develop diabetic neuropathy - weakness in the hind legs causing a flat-footed or plantigrade stance. This is a sign that the condition is advanced and needs urgent attention.

How is feline diabetes treated?

Treatment involves twice-daily insulin injections, a high-protein low-carbohydrate diet, and regular blood glucose monitoring. The diet change alone can significantly improve insulin sensitivity - switching from dry food (which is high in carbohydrates) to a wet food or prescription diabetic diet is an important part of management.

Many cats achieve remission within weeks to months of starting treatment, particularly if they were not severely diabetic at diagnosis and if dietary management is strict. Remission means the cat no longer requires insulin - though the underlying predisposition remains and monitoring continues.

What does monitoring involve?

Blood glucose curves - measuring blood glucose at intervals over several hours - help us adjust the insulin dose. This can be done in clinic or at home with a glucometer. We also monitor fructosamine levels, which reflect average blood glucose over the preceding two to three weeks, giving a broader picture of control.
