How much should I feed a nuetered male cat which is about 5 months old? I feed him both wet and dry food, but he is always asking for food. The vet told me to not overfeed him since his metabolism will slow down due to being fixed. My friends cat got fat after being spayed, and I don't want the same to happen to Buddy. He is an indoor cat and not very active, he likes to only sleep, eat and be petted, he doesn't play too much, although I do try to push him to run around each day a little. Just hoping for some advise. I don't want to overfeed him, but of course I definetley don't want him to feel hungry either.
