But cats with persistent and pronounced hyperglycemia usually require insulin. About 70-80 percent of feline diabetes patients fall into this latter category. Cats with diabetes must eat regularly to guard against insulin overdose, but owners also need to control food intake so the cat doesn't become obese. One strategy is to fee the daily food allotment in measured installments. Clinicians usually recommend two or three meals per day.
Some diabetic cats benefit from special diets rich in fiber.
Fiber tends to slow down digestion, thus preventing sudden spikes of blood glucose. High fiber foods can also help obese cats lose weight - which can decrease the need for insulin in some cats. But never shift your cat's diet without first consulting with your veterinarian. It a diabetic cat finds a new food unpalatable, he may eat less, throwing his blood glucose out of whack. To be on the safe side, always make sure your cat is interested in food before you administer insulin.
