It could be he's still upset. My boys aren't exactly lovey dovey with him but the tolerate him with no hisses etc. I tried 9lives and he ate it for a few cans but then he stopped. I may try it again. I'd like to find one food and stick with it so he doesn't get an upset stomach and I can monitor his poopies more consistently. The woman at Petco told me that different foods produce different bacteria so to try to introduce new foods gradually..unfortunately when he decides he doesn't want something, he doesn't want something period!!
Dr didn't mention an enlarged tyroid but I'll try to call him and ask. Like I said he isn't the most forthcoming with info!! I think I can get amoxi from the shelter.
I had a part siamese before (though he was a tuxie). Thankfully Smudge doesn't talk nearly as much as Jersey did!!
Thanks again everyone!
