When kittens are getting enough to eat, they’ll get a nice big fat belly. Well-fed kittens won't feel too ribby over the back. If you have food down and the kittens are eating it, your cat will self-regulate. If your kitten is not eating, then you should be worried and take them to the vet.

A lot! They have tiny stomachs, so you don't need to restrict how much they're eating. When they're over a year, they can get fat. You'll need to be careful with what you feed them. But as a kitten, they may eat every couple of hours.

It's best to use a kitten replacement milk from the pet store containing more appropriate calories and nutrition for them.
