When can kittens eat kittens food?

It should be able to. Kittens are usually beginning to take an interest in their mother's food at this age. The best food to feed them is good quality wet food, mashed up and mixed in with a little kitten milk (never cow's milk) or water if need be to entice them to eat. You can even try and see if they will lick a tiny bit off your finger or off their paw.

Always have a shallow dish of water out, and feed small portions of food as frequently as you are able. It is best to put down food for them (on a plate, not in a bowl is a plate is easier to eat out of) at least six times a day.

The weaning process can take several weeks, so always allow them access to their mother's milk during this time and they will wean themselves off naturally.
