Help

[Cerra]

Hi, I have a trio of females, whose noses have gone between being bald
and being furred. The other day I noticed that one of them had one of
her eyes "leaking" mucus. I promptly switched them to just plain paper,
and their noses got bald again. Please help, they look like crap and I
don't know what to do.
Thanks in advance
