I have a young (less than year old) male tiger cat. I have been feeding him Science Diet dry food. I started out with the Optimal formula, but noticed sometimes he threw up so I switched to Senstive Stomach. He still throws up sometimes. I am wondering if he just doesn't chew it up. I want him to have a good dry food and so far he hasn't had any UTIs (knock on wood) and he hasn't had any hairballs. I would like some suggestions on a good dry food. I buy his food at Pet Supplies Plus. How good is Taste of The Wild?
