Have Cat Questions? Ask a Cat Vet Online.
Hello, I'm Dr. Deb and will do my best to help you today.
I'm sorry for this concern for your cat. Her behavior certainly sounds a bit unusual but I'm glad that she seems to be greatly improved or at least she's not behaving as she was.
On the off chance that she might still be a bit nauseous, you could give her over the counter Pepcid AC (aka Famotidine) at a dose of 1/4th of a 10 mg tablet.
I'd probably also withhold food for now and just give everything a chance to settle down.
Hopefully, whatever triggered this intense reaction was a one off as they say but a vet visit to have her checked out in the morning isn't a bad idea.
I hope this helps. Deb
