I made up an old trash bag box that I put hay, pellets, a couple raisins, and carrots in for my bun, so she has to dig through the hay to get the yummy things. She loves it. ^_^ she also has this ball with a jingle bell in it she likes to pick up and throw around. She also likes running through oatmeal container tunnels and going "rabbit bowling" (stand up paper towel and toilet paper tubes and she runs at them and knocks them over with her nose!)
