One of my guys is scratching/ overgrooming right now due to suspected chicken allergy. We're in the process of finding a food that works for him. He is having bad hairballs because of the overgrooming....so my question is, what do you guys suggest I try to help him with the hairballs? I think most hairball foods and treats are out because most contain chicken products of some sort. So what do you think? Lecithin? Pumpkin? I'm hoping once we get the allergy sorted out, the hairballs will take care of themself.
