Oh Henry! I am just now seeing this thread. I am glad he went to been checked over a t the vet. I do NOT like a sore mouth, ugh!

Prayers that the meds kick in quickly and he starts feeling better and eating.

I hope you and Linda both keep him indoors during this time. It is easiest to keep track of what he is eating and how much, what is being deposited in th elitter box, etc.
