DH thought it would be awesome to have a ZUZU pet (the little toy hamsters) for Sadie. He got one and brought it home, set it on the floor and let it run around. Sadie LOVES it. she chases it, picks it up and bring it to her bed to play. it makes noise and runs around the kitchen floor nad she grabs it over and over again. she's funny. DH is going to buy the hamster ball attachement so she can't get to the toy and break it, but has hours of moving hamster ball fun !!
