I saw that. it would be a waste of money to me. I don't like rodents of any kind in my house. I set traps when I have to. My sisters had a gerbil they talked my dad into getting but it had to stay in the garage. The cat had a gourmet lunch that very same day. Back then the gerbil cost $2.00. That was a lot of money 40 years ago for a rodent. That's a lot of money for one today.
