My 12 week old kittie "Savanna" has just discovered my amazon parrot "Pedro." I caught Savanna trying to reach up to the bird and it scared me. My calico "Darla" is bigger and sometimes she'll get near the bird but she knows not to get too close. Now I'm afraid to leave Savanna loose. My bird could hurt her. Any suggestions on what to do to keep Savanna away from Pedro's cage.
