Hi all! I am currently pig-sitting for my cousin, her ( the cavy) name is Pudding, and she is 3-4 years old. She is missing a LOT of hair. They are treating her with Ivermection, and have been for a few months. It doesn't seem to be helping at all, and her bare skin seems perfectly fine- not scratching, no bumps, redness, or dandruff. So I think it must be something other. The thing is, (prepare yourselves), her enclosure is a 10 gal. aquarium. I KNOW!! She is out a lot, but I know this doesn't make up for it. I would like to keep her, but I want to be sure that she doesn"t have anything that could be passed on to my 2 guinea pigs. Could her hair loss be a result of being cramped? I appreciate any advice! (Again- I realize that the whole set-up is horribly wrong.)
