I fed my kittens mostly Purina dry kitten food and a mix of Tractor Supply and Friskies wet. The wet was a mix of their canned foods, mostly pate. I always mixed it up, thinking it would avoid having a picky eater as an adult cat. Never had any picky eaters, but I can't really say if what I did worked for sure.
For wet, I mostly feed Rawz and Tiki Cat After Dark, though occasionally I'll buy them a can or two of Feline Natural. For dry I give them Ziwipeak air-dried.
