Sometimes this can be genetic, but mom is sure it is from feeding us cats too much dry food. Dry food is bad for cats, as it is way too high in carbs, and well, it is DRY! Cats need a lot of water IN their food, and we are obligate carnivores.
The ideal diet would be for us to eat mice as mice are mostly protein and fat with only about 5% carbs.
But we are house cats, and mom won't let us catch mice outside so she has adjusted our diet to high protein canned food, and eliminating almost all dry food (except for stubborn Chester), and giving us real 100% Chick-Hen treats.
Diabetes and many other bad diseases are caused by cats eating too many grains and carbs. Have you ever seen a cat in the wild hunting down a potato or a corn cob? I think not!
I am a cat, and an obligate carnivore and I love protein! Give me meats or chick-hen, so I will live a long healthy life!
For my diabetes treatment, I am down to 1 unit of insulin twice a day. My blood glucose is hovering around 100, and mom hopes that I will soon be OTJ (off the juice), with the diet change.
