I don't know what the vet would saybut I used human yeast infection cream (very small doses) on Merlins sores from his out brakes of rashes (funcgal ) as part of his cancer. cleared them up in a week or so. rub it in to the infected area . I would hold him from licking it for 10 mintues or so letting it get in. might not hurt to try on nose if it works try a litter in the nose on a q tip.
