Elmer and Bob go wherever they want and do whatever they want to do.. but my place is just 2 rooms with wall-to-wall carpeting plus a very small bathroom and kitchenette.

Neither of them goes to much trouble to climb or jump. Bob hauls himself up to the top of his 2-story cat condo. Elmer jumps up onto my bed.. or rather, kind of hurls himself into the air to land on it wherever.
