We have 2 new female 10 week old Guinea Pigs. One of them seemed to have a fungal infection on her head between her eyes. Very localised. We took her to the vet. Who said this could be what it is (as opposed to an injury) and suggested some canesten cream twice a day. The problem is that we can't stop her scratching so the wound is quite bloody and isn't healing. Not sure how we can help it to dry out and have chance to heal. Has anyone else been in this viscious circle? Is there some kind of anti-septic powder for things like this? Any other wisdom?
