I have a very very fat gerbil. We have a pair of gerbils that we are breeding to provide gerbils as feeders for my ferrets (the like a variety of prey items). I plan on holding back a female or two from this litter to make another breeding group and expanding the gerbil colony a bit more. (We only have one breeding pair).
I'm not sure when she is going to pop but she is huge! I'll post pictures when the babies arrive.
