Well the Sumatran Short Tail is packin on the inches and weight, hes simply amazing! I mean when I bring a rat into the room if its thawed out he comes out of his hide ready for action BEFORE I even open his enclosure,on the flip side he has become my lap snake, late at night when Im watching reruns of the x-files Ive got him in my lap and we just chill together.Sometimes he puts his head ontop of my arm and stares at the TV, I have no idea what he sees but its very cool.
