Just like humans, cats can also develop diabetes from eating too much carbohydrate. There has recently been a sharp increase in the number of pet cats suffering with diabetes, and modern diets are to blame. You have probably noticed that more and more cats are becoming overweight and obese. Along with the excess weight, their blood sugar level is also rising. Cats are carnivores. They are meat eaters; that’s how their bodies are designed. Unfortunately most processed cat food these days is based on cheap carbohydrates like wheat, corn, rice and oats. Grains are a lot cheaper than meat, that’s why most pet food is based on grains. Cats are basically being fed salty biscuits flavored with a little meat, chicken or fish, with added vitamins. This is very far removed from their traditional diet. When cats eat carbohydrates, their blood sugar rises and in response to this, their pancreas releases insulin. Any person or animal that regularly eats a lot of carbohydrate will secrete a lot of insulin into their bloodstream. Insulin is a fat storing hormone. Eventually insulin can lose its ability to control the blood sugar and then diabetes develops. In most cases, diabetes in cats can be prevented or even reversed, if the cat is fed a natural species specific diet. Reference
