Marley lost her crate

I have a surreal situation at my house, Marley and Bob both like to hang out in the crate. How weird is that! This last week Bob has decided he likes the crate and has spent a significant amount of time snoozing in the crate...every day. This means Marley is not allowed inside, which kind of defeats the whole point of having a crate. Does this mean I have to buy another crate? People with normal pets don't seem to have these kind of situations.
