And this is why I've never liked that vet's office. I called to ask their opinion on her not eating, if I should be worried, what to do... "if she's not eating you should probably bring her back in". That's it.
If it comes to that, I'll drive the half hour and take her to one that cares and knows more.

Edit: And why I love my vet - called there, and while I did have to wait on hold a while for her to finish up with someone, the Dr. herself got on the phone with me, said that was indeed concerning, and we might switch to Baytril, and she should have some Meloxicam for the pain. I'm gonna take her over now.
