I'm just getting weird baby rats right and left. I have a tub with a blue male rat, two sister hooded rats one with a snip and the other with granitish markings on her back.. and a pink eyed white female.
All parents have normal coats and ear types. I'm not sure which one was the mommy of this litter, but I think it was one of the sisters.
Anyway, I have four approximately two week old babies. They all look like double rexes (homozygous rex) ie they are more hairless than rex. Curly whiskers and a very thin coat on the back.
With no rex parents, this is just odd.
