My sweet Stewie, who is 10, has diabetes. He is a short haired black cat, weighs 6.4 kg. He is a bit portly, but vet said not obese. He starts insulin treatments on Monday. She uses prozinc. He is active, happy, great appetite. He drinks and pees a bit more than normal. He also might have some arthritis in his back legs. He will be going on a just canned food diet. He was on canned and dry food along with my other black cat Sammy who is younger and has no illnesses. I feel confident that my vet and I can get this under control. He's a remarkable cat, never met a cat like him. Here's a pic of him not being impressed. haha. I'll read the forum threads to learn all I can. SO happy to find this support network! Thanks for being out there.
