I feed my kitties science diet and they really like it. I wouldn't feed them dog food, it's not good for cats. Cats are pretty easy to take care of, they can take care of themselves. All you need to do is give them love, a few toys, feed them, and clean out their litter box. And I agree with Tux, you should take then kitty to vet for a checkup just to make sure everything is ok and they can also answer any questions you might have and some vets even send you home with a kitten care kit with little pamhplets and such.
