My 14 year old cat Punkin was diagnosed with diabetes on Friday and I'm already in over my head. No problem giving the insulin. Punkin is really easy to handle. He's very trusting. And sweet. The problem is getting him to eat right after the injection. The vet gave him an appetite stimulant Friday morning and he's been eating a LOT since then. He is not a foodie at all, so this has helped. The problem is he's eaten so much that he's now very constipated. So much so that he ate very little this morning and nothing since. I got as much Laxacat down him as possible, but most ended up on him instead of in him. He keeps trying to go but so far, only 3 little turds...one at a time. I have to give him another injection in two hous. My question is, is it safe to give him the injection and then if he won't eat, give him as much Nutri-Cal as possible?
