There is good news for cats with diabetes. A new food has just come on the market that can reduce the need for the amount of insulin and in a large number of cats stop the need for insulin at all. The name of this food is Purina DM and at this time it works only for cats. If your cat, or you have a friend with a diabetic cat, I recommend consulting the vet for more information.
I realize daily insulin sounds like a big hassle for you and the pet, but most diabetic dogs and cats don’t notice the shot and the insulin injection makes a world of difference in the way the pet feels and acts.
