Our new rats have revealed extremely varied personalities. Teggs, the clearly dominant rat, will stash food away and attack any rat who comes close to it; as a result she is much heavier than the others. Two of the pictures below show what damage she can do when she gets mad. She doesn't bite humans; that is Twitch's job, an un-handlable rat. Jasper is at the bottom of the rat-pack, extremely friendly (with other rats and humans) but a bit dim; she likes to cosy up to Teggs, who then attacks her. Sprite is the most interactive, and shows the most intelligence and desire to explore.
