as you know we have three litters of ratties right now. so honestly... who knows whose pups are whose.

our male is rex. some of our females are rex as well.

so we have two pups who, as they are getting older and scarce with the fur! one is almost bald on the top of it's head and the other is balding all down it's back.

i believe we put down the balding-down-the-back one this week... but the little bald head one is still around.

so... is this overgrooming or is it something genetic?

what do ya think?
