So I have a 10 year old Maine coon, he recently went off for a couple of weeks and has come back skinny, and has a few bald patches, I've now made him a house cat and have been feeding him every few hours as he's more of a grazer in hope to fattening him up a bit. I'm giving him wet kitten food as I was told that has more calories - but would it be better to feed him senior wet food ? I give him chicken and some raw meat as well as tuna. I think he has a few bald patches as he's stressed so I'm hoping these grow back. Is there anything else I could do?
