Katie, I again have tears in my eyes. This is going to take some time, but he just has to get better. He looks so great! And there are SOO many people here pulling for him.
Did you happen to ask the vet about the feeding tube Jen mentioned? Or some way they could get nourishment into him since his tongue is so sore? I think that will help him tremendously.

We are still sending out our strong positive thoughts that Andy will overcome this and be back home with his siblings and his meowmie very soon.
