yup, I used to breed Gerbils. also Missy(RB) had 2 litters of Guinea piggies in my house, only the first litter was intended, with a nice size litter of 3, Poppy(RB), Patch(RB) and Smores. the second litter was accidental, basicly Missy's pregnant with those 3 was very odd and we got very confused about when the heck she was due..IF she was even due(one minuts she would look very preggo and the next she was look totally normal so we hadent known if she was preggo, did she abort, was it a falsey or what) well she threw us off so much that when she did give birth her nursery cage was not ready so the male got her again, that one was a normal pregnancy and she gave birth to SIX babys 3 males 3 females.
