Yeah, I bought a female rat from PetSmart once (I wouldn't normally but this girl was just too damn cute to pass up) and when I told the girl that I keep snakes she was absolutely horrified! They make you sign a waiver saying that they will not be used as food, that if there are any problems you'll take them to a vet blah, blah, blah. I assured her that she was not going to be food (didn't mention anything about her babies though!) and they sold her to me.
