Your vet needs to get w/the program. There are several meds that you can safely give a pee cat. My local vet is out of the loop, too, though. She didn't even know what the antibiotic Convenia is and when I told her that my other vet gave Coco Puff an injection of it and that it lasts for two weeks, her face went blank. Vets need to continually take classes and courses, etc. to keep up w/the newest meds, procedures, etc. I'll say it again: Clomicalm.
