so I've decided to forgo the raw diet for now, at least until I can talk to a cat nutritionist. I've actually found out (out of boredom really) that both the Wellness brand and the Blue Buffalo are only a few dollars more than the Purina Pro PLan that my cats have been eating, and obviously much healthier for them. My question is, which one is better? Which ones do cats have fewest reactions to, and do either of these do well at keeping the hairballs away? one of my cats is prone to hairballs, and the Purina pro plan has done a good job of helping her to not have hairballs, but I would like them to be on a healthier food. any advice or recommendations?
