Thanks for the response! I have done some research about feeding gerbils to these snakes and that is the thing I run across every time. They could become hooked on them and not eat anything else. I will step her up to rats after she is finished this batch of mice. I will also check out the price of gerbils when I am at the pet store to get an idea of what the price difference would be. It may be within my means. Either way I will just ween her up the food chain if I can.
