Growth on Mouse's Ear
Very new here, so I apologize if I'm ignorant of the local customs.
I have a white male mouse who is at least 21 months old, and I've recently noticed a growth on his ear. I have a picture, but I'm not allowed to post it, if its not bad form, I'd be happy to type it out like this:
I can't seem to find any exotic pet veterinarians in my area, so I'm not sure where to even start. Has anyone seen a growth similar to this before?
Any help would be greatly appreciated.
