Ive just gone to check over my piggles for the day, and noticed my little pluto has a slightly crusty bald stripe over one eye. It doesnt seem to be itchy or sore, the hair around doesnt seem to be falling out or anything but the skin looks a bit like its got white crusty thick dandruff (like when babies have cradle cap). Ive scrubbed the cage and houses out and separated pluto from his ladies. Ive treated with xeno 450 for all the piggles as a precaution, but I'm thinking it might be fungal? Is there a routine treatment to try as its a small patch and isnt bothering him or should i go straight to the vets?
