My boyfriend and I have two BP's, one is 2 1/2 feet, one is 3 feet. They were picky eaters when we first got them, but now they love to eat. Neither will eat rats, so I thought a couple mice a week should be allright for each of them. When I'm not there, however, by boyfriend feeds them at least 3 mice a week. In the past three days he let the smaller girl have 4 mice. I'm worried that this could be unhealthy and make them fat, which would only lead to other health problems. Am I right?
