The other day a new housemate moved in and Sally and I went to say hello. While talking to my new hosemate I noticed some movement and so got to meet Alfred my housemates pet rat. Sally was studying Alfred intently and then worked out what he was and started going absolutely bananas. She wanted to jump off my arm and go and rip him to shreds. Alfred quickly jumped back in his cage and I took Sally back to my room. Lucky Alfred
