First things first; Bring it to a good vet for a check-up, shots, de-worming, etc. They should be able to recommend a good kitten diet. Kittens need LOTS of calories to grow and run around. If the kitten hasn't been weaned, there is kitten milk replacement available from most pet shops. Also, I don't recommend that cats be "outdoor" cats anymore; there are coyotes, cars, feline AIDS, feline leukemia, in addition to the monsters in human form that would prey on innocent animals. It's just too dangerous for cats to be outside these days.
