Diabetes is a real problem for cats in this country, but the good news is that we now have a much better understanding of this condition, and even better, we can cure it in many cases. Best of all, we are learning how to prevent it, which is the ideal strategy for a healthy, happy cat.
Cause: It’s now believed that many cases of feline diabetes are caused by excess carbohydrates in the diet. Dry cat foods in particular can be high in carbohydrates. Cats are not designed to properly metabolize carbohydrates, and cats on dry food may become obese. Additionally, the excess of carbs forces the pancreas, the organ that produces insulin, to overwork. Over time, the pancreas can become exhausted, and lose the ability to make sufficient insulin. This lack of insulin causes diabetes.
Treatment: Most diabetic cats have not permanently lost the ability to produce insulin. In order to rest the pancreas and allow it to return to normal function, cats are given twice-daily insulin injections. It’s essential to carefully regulate diabetes so the cat receives the proper amount of insulin to restore the function of the pancreas while avoiding low blood sugar, a potential side effect of insulin treatment.
The second essential component of treatment is the cat’s diet. For the best chance of curing diabetes, most cats should eat a canned diet formulated for diabetes, or a canned kitten food. Be sure to consult with your veterinarian regarding the best diet for your own cat.
A note of caution: Cats who refuse to eat can become very ill. Any diet changes must be made cautiously, with careful monitoring of the appetite.
For optimal treatment of diabetic cats, it may be advisable to consult with a veterinary internal medicine specialist. We have two on staff at the ASPCA Animal Hospital: Dr. Pomrantz and Dr. Frank. To find a veterinary internist in your local area go to www.acvim.org.
Prevention: We all know that “an ounce of prevention is worth a pound of cure.” For diabetes prevention as well as urinary tract and digestive health, we advise feeding cats canned food in meals, rather than allowing them to graze on dry food. Just remember that when attempting to make any change in a cat’s diet, such as from dry to canned food, patience and caution are essential. Never allow a cat to “hunger strike,” which can cause serious illness.
