I have to agree with the others it is silly. Why do rats and mice have such LARGE litters? Could it be that the pinkies are "popcorn" for almost any small prey animal? They are ment to be eaten. I enjoy my rats. My breeding plan is centered to get large, sweet tempered rats. I just gave away 3 babies to a pet home. The little girl was extactic to get them. But the reason I breed is to feed all my snakes. I just killed a pig so I could have ham... maybe someone should euthonised me.......
