Awe... poor kitty (with Star Trek sounding name, lol). I hope he'll be ok.

Can you call Joyce and talk to her, or will Kathy W. ok it?? She's taken in a bunch of sick cats, even though they were sick, because they were pedigree. Or, put it back to Dr. Hess and see if she'd try to cover some of the $$ if you tell her 1x1 said no. The worst she can say is no, but you never know unless you ask.

Good luck!!
