WOW - Thank you for that warning. I hadn't known about those issues.

I just spoke with the vet. She told me that Baytril can cause neurological side effects, and she wants him off the meds for 24 hours. If he is still acting strangely tomorrow, I'll need to bring him in.

What's odd is that he was on this med before. Who knows why he'd react to it this time and not the last. I feel like a terrible cat mommy for making him suffer the last two days. I guess he'll be getting a new toy tonight to make up for it.
