Salem has cage envy!

Salem our cat. He has a case of cage envy. He is our only pet not to have his own cage. He has the run of the house and goes outside during the day. He likes getting into the ferret cages or rat cages when they are playing outside and will sleep in their hammocks. Today it is raining and he won't go out. We have an empty cage on the sofa as we used it for Gem-Gem temporarily til she went into the girls group. Following this photo being taken Salem fell asleep on the hammock. It begs the question... Do I get him a crate and hang hammocks in it for him to have his own cage?? Lol
