Cat health - diabetes

I earlier mentioned some thoughts about the disturbing rate of diabetes in cats. The cause of diabetes in cats is unknown, and, as I mentioned, some have suggested that a dry food diet may put cats at a greater risk of developing the disease than wet food. Because dry pet food has a higher carbohydrate content than canned food, it has been argued that it is less suitable for an obligate carnivore such as a cat. However, a new study by researchers at the University of Missouri-Columbia claims that it is weight gain, and not diet, which is the cardinal contributor to this problem. The study compared a colony of cats in California raised on dry food with a New Zealand colony fed canned food. After comparing glucose tolerance tests, which measure how fast glucose is being cleared from the blood after eating, researchers found no significant difference between a dry food diet and a wet food diet.
