I'm glad, Joyce, you are taking kitty to the vet. It sounds like an infection to me and they don't go away by themselves. That's been my experience anyway..... Vets are expensive and I have much sympathy for you in that regard. Usually, though, they will take payments.
Personally, I think I've spent much more on vet bills then I ever did on my children's doctor bills. I just hope he feels better real soon.
