Oh my gosh, I DO hope your poor little kitty is feeling SO much better, really soon. I just posted above, to the post about "keeping kitty's gums healthy" and was talking about how I almost lost my little Miss Missy cat. She had her teeth cleaned (and had tooth problems ) and two teeth fell out during that tooth cleaning. The vet I had then, did not give her any antibiotics and I very nearly lost my dear little cat. It is very frightening when all the different things begin to go wrong--and all at the same time!!! I felt like I was going through it all again, while I was reading your post. My cat did not end up having surgery, but I know how frightened I was as I was going to a different Vet's, (with the loud encouragement of the posters on this site!!!) I had assumed my cat had a post-op antibiotic shot, and she didn't... and NO antibiotic drops either, for me to give her. So she got sick--and went downhill REAL fast, like your kitty did! I really hope your kitty recovers very quickly and he is back home and happy with you again, SOON!
Keep us posted, OK??
