Hello,
I would ask your vet about the following;
Giving sq fluids at home daily, adding a short course of a steroid and the latest opinion on prazosin’s efficacy. (I don’t use it).
Also I don’t use vinegar.
These are a matter of experience and preference. Therefore please ask your vet or find a feline only practitioner to help.
Get her to the vet for a dental. She may need an extraction.
