A creature that originates from the north east but moves down south for warmer weather and a reduction in pollution. They can be identified by having rabbit like hair, it is a peaceful animal but can get very agressive when agitated by magpies or black cats. It is best to avoid in the wild as they may be hungry and attack.
Look at that little cai over there, isn't it cute!
