My kids and i checked some of these out at the pet store.I would like to know all the ins and outs of owning one of these creatures.What are they like to live with? Do they sleep in the cage at night? Do they bite? Can they be safely handled by kids all the time? Will they live with a very casual cat? Do they use a litter box? Someone told me they are horrible and pee everywhere--is this true? Thank you for all the information guys!!!!
