The Chlorhexadine that my vet gave me is specifically for cats, so it doesn't taste so bad plus it has a long tip that makes it easy to squirt on the gums. I do know how difficult some cats can be w/administering meds, though. Puddy was like that until she became so sick that she cooperated. I know how nasty it tastes for humans; I use it myself. LOL He also told me that I can put it right in her water fountain and not have to worry about her swallowing it, so maybe talk to your vet about it and see what s/he says.
