Feeding a diabetic cat: why low-carbohydrate matters

Here's something worth knowing on day one: for diabetic cats, food isn't just fuel — it's one of the most powerful tools you have. Cats are obligate carnivores, built to run on protein and fat rather than carbohydrate, and current veterinary consensus (including the ACVIM 2022 feline guidance) favours a low-carbohydrate, higher-protein diet for diabetic cats. Get this right early and you're giving your cat the best possible chance — including, sometimes, of remission.

Why does carbohydrate matter more for cats than dogs?

Because a cat's metabolism isn't designed to process large amounts of carbohydrate, high-carb diets keep blood glucose elevated and make diabetes harder to control. Reducing dietary carbohydrate lowers the load the body has to manage — which is why low-carb feeding does so much heavy lifting in feline diabetes.

Wet food or dry food?

Wet (canned) food is often naturally lower in carbohydrate than kibble, which typically needs starch to hold its shape — so many vets lean towards low-carb wet diets for diabetic cats. Wet food supports hydration too. That said, the perfect diet your cat refuses helps no one: the right food is a low-carb one your cat will actually eat, consistently.

Could the right diet help my cat come off insulin?

Possibly — and it's worth holding onto this hope while staying realistic. In cats, combining a low-carbohydrate diet with good early glucose control and a healthy weight gives the best chance of diabetic remission, where the cat maintains normal blood sugar without insulin. Remission is never guaranteed and is not a reason to skip insulin or vet care — but it is real, and early consistency is what earns the chance.
