Carter loves birds, so we put up this bird feeder for his 'bird friends'. He'd love a pet bird in a cage, and I have nothing in theory against this, except we already have a cat--a cat who has proven to be an able bird hunter!
Anyway, we all really enjoy watching robins, wrens, and finches come to feed by this window. For Otis it's very exciting, albeit FRUSTRATING. He stalks them as best he can, and eventually ends up with his paws and nose fairly pressed against the window, all for naught. Poor kitty.
