i fed off most of this litter. i saved these three because they were getting bigger than i wanted to feed at the moment. Then i noticed they are losing their hair. The mom is a rex and the dad is not. they lose more hair every day. These pics are from yesterday and when i check on them today they have lost all hair except the head and a few small patches.. are these double rex hairless? should i keep them as breeders or feed them off? sorry for the crappy pics.
