Today Belle spent a while in the second floor compartment of her kitty condo. The condo has two floors, and there is also space at the top of the condo, which Belle calls the "penthouse".
Belle likes the condo because it's right next to the heater, so she can curl up in the second floor compartment and let the heat waft up to her. I have a feeling she won't be using the compartment much once it gets warmer - it will be penthouse time then.
Belle doesn't ever use the first floor compartment of her kitty condo. I asked her why once, and she told me that "the first floor is for commoners". Sometimes Belle can be a bit of a snob.
One of the nice things about the kitty condo is that it serves double duty as a scratching post. Prior to the kitty condo, we had both wooden and rope scratching posts, neither of which Belle ever used. She didn't like scratching wood or rope nearly as much as our couch. Thankfully, when we got the kitty condo Belle started using it as her primary scratching post, though she still likes to let the couch know who's the boss occasionally. And it ain't Tony Danza.
