I feed them the best I can...making sure by-products in their food is mostly bye-bye. The kitten has some indigestion and maybe an adult cat of my five. I'm thinking they have indigestion or something. I've tried and still have the good bac to add to food...tried other things. The mineral oil (1/2 t) added to food when constated works great. I noticed a very soft fir tonight and figured it was the oil he got with the one meal. But the breath is still bad. Any ideas?
