Shadow, Angel, and Little Orphan Annie all three absolutely love theirs. They've even been taking turns sleeping in them. Shadow, especially, loves to play in them. He'll jump out of one and into another in a single bound! He is absolutely hillarious to watch! My son will get right down beside them when Shadow is in them, and call Shadow's name, and Shadow will pop out real fast and try to "attack" my son, all in fun. We got ours at Wal-Mart, the day I brought Little Orphan Annie home from being spayed. They've been successful at distracting Shadow from her while she's been healing.......
