My 15yo cat was diagnosed with diabetes today. I gave her her first insulin shot tonight. I have to take her in Saturday morning so they can check her sugar levels (not sure that is the correct term). They will teach me how to check her levels myself (not really looking forward to that but hopefully it is easier than I think it will be). I hope we can find the proper dosage of insulin for her quickly. He said not to change her food for now. Any advice from other kitty mommies who have gone through this would be appreciated.
