I noticed last night that I can really easily feel Amigo's backbone, he seems to have lost a lot of wieght. All of the rest of the farm cats are doing really well on the food they are getting right now, he's the only one who has lost wieght. should i try (hint word is try!) to feed him a differant brand of food seperated from the rest of the cats when i go there in the evening? He is still very active, playing with everyone on the pile of straw bales. I am just concerned that he has lost too much wieght. Is there any food that i should try give him that could help? Do i try get him to eat more wet food? Could it be that he just has a problem with what i am feeding everyone? The too skinny cats have all gained wieght on their food, so i don't understand why amigo is having problems. any advice would really be appreciated!
