Q. My cat just started drooling. Our local vet who did blood work and X-rays but can't figure out what he's drooling. Any ideas as to why that might be?

A. If he hasn't had a sedated oral exam, that needs to be done. There can be items lodged in the mouth that can cause excessive drooling, as can dental disease. Sometimes there are nerve issues, so a good neurologic exam should be done as well. Feline infectious peritonitis, which is harder to diagnose, should be considered as well. Probably the most common thing I've seen causing drooling in cats is the ingestion of irritating plants or very noxious or bitter substances.
