Yup that is what I feed my six cats. Sometimes I get expensive food with coupons and mix it in, but I think it is because I read the ads that talk about how their food is better. I don't know

Poops are small and not particularly smelly at all so I would not notice if another food changed that. I find hairballs and throw-up piles now and then but am not sure if that is just normal for six cats - mayve a hairball once or twice a week.
