I have a couple rats that seems ill, but I couldn't find any info on how to help them. Can anyone help? Thanks.

1 PEW about 3-4 months old has a rough and thin coat of hair and her whole body seems pink in color, and the eyes are smaller than normal. Is it Myco (Mycoplasma pulmonis)?

Some small rats and some mice have that wet area around their anus and genitals. Is this "wet tail"?

I can't afford the vets. Anything I can do to bring them back to health? If not, I'll have to put them down.

Thanks!
