Hiya
,
I'm sorry to hear about your kitty's diagnosis, but I can tell you that lots of cats (and dogs) can live normal lives with diabetes. I used to be a vet tech and saw quite a few diabetic animals. Good luck with the food, it's quite possible that will do the trick. If you DO end up having to give your kitty insulin, just know that it is VERY easy and most cats don't seem all that bothered by it. We had one client who always gave her cat his injection right when she came home, so he connected the excitement of her arrival + lots of cuddles with getting his insulin. He even sits and waits at the fridge while she gets it ready for him!
So good luck, and try not to worry TOO much about it.
