I use to breed gerbils about 4 years ago but I sold my breeding pair and moved onto hamsters. I brought 2 gerbils about 3 months ago from two different pet shops to make sure they wernt related, as I want to start breeding them again. But when I saw these gerbils up for adoption I couldn't say no. But I really don't know what to do with them.. Also if the girls are pregnant the babies may be born with disabilites.. Lets just hope someone comes along, I'm going to see what the pet shop tells me what to do.. But also I think gerbils don't show signs of pregnancy until about a week or so before the birth..
