Pepper, Willow and Willy loved it. But, when we put all 3 in there, Pepper and Willow would pick on poor Willy.
Now, we usually take Pepper by herself because she's made a friend in the Spaniel down the street. We roll by his fence and he comes running over wagging his whole body and he and Pepper have a conversation.

Cammie doesn't go because she never wants to be more than 3 inches from a heat source.
