What To Feed A Baby Kitten 6 Weeks Old?

I just got a kitten and I’m feeding her wet food. She has been eating Purina One but now I’ve heard she needs to be eating kitten formula since she is only 6 weeks old. What should I get?

I feed my cat dry food and the kitty loves it, so we don’t even give him wet food if he doesn’t want any. The vet says he’s in decent shape for his age too!
