My current kitty needs a hairball formula and he ended up liking blue buffalo hairball formula with chicken. I used to be able to give him wet food and mix in some pumpkin or squash but he's not as fond of wet anymore. I'm sure there are healthier dry hairball foods, tho. Looking for suggestions to try if blue buffalo is still really bad for him. I've read some oldhorror stories on BB so am worried. Thx!
