I absolutely hated breeding them. I've spoke with a few other people in the area and they all stopped breeding for the same reason. They waste food, they chew out of everything, they are dirty, and evil. They also smell more than rats. Once they get loose they are all over your house and chew EVERYTHING! I found one in my kitchen drawer chewing up all my utensils! ASFs are illegal to own in many states for a reason, they are terrible creatures.
