We brought a big dollhouse into the nursery, and the kittens love it! They spend all kinds of time playing and lounging around in it. This is where they prefer to sleep now at night. They can walk from room to room through the doors, look out the windows, climb up the stairs, wiggle through the elevator shaft. or just right jump up to the second floor. They can even climb onto the real windowsill through one window of the dollhouse. From there they can climb on top of the house! If they are not careful they will slide off the top of house onto the lower side roof and then into their litter box, which they seem to think is fun, lol!
