Since this food does contain grains I'm suprised that his stools are soft. I was thinking that he was on a grain free diet and some cats will have have stools while their systems adjust. I've just started feeding my cats Wellness Core dry which is grain free and some of the Wellness grain free canned foods that they make. I did notice that my girl Pearl was having some soft stools but she always does at first so I'm not worried about it. They also eat some of the grain free canned food that they were eating before. I decided to switch because they just weren't doing as well on the Natural Balance and it has too many carbs in it for my liking.

My kittens are still eating a mixture of Natural Balance Green Pea & Chicken and Wellness Core and they'll be on this mixture for a while because I want to wean them off of the Natural Balance more slowly since their digestive systems aren't mature yet.

If I was you I'd just stick with the Wellness for now. Paulie hasn't been on the medicine for very long and it'll take time for his digestive system to adjust. If you keep switching foods then his system will never adjust and you'll never know what's working for him. Just try to be patient and try not to panic. I would still keep the dermatologist appointment just to be on the safe side. Good luck.
