Wow, this jungle gym would make one – or several – active kitties very, very happy! With six plush fur hammocks, two cozy condos, and 100 carpeted "catnector" beams, the modular cat playground ($250)  would keep pets busy . . . but looks to take up quite a bit of space at six and a half feet high (and long) and another four feet wide. Is your pet's playroom big enough for this creation or do you prefer to keep kitty's gym things on a smaller scale?
