Scary little hamster

Elizabeth loves her but she scares me to death. Her name says it all, "Nippy T." I'm not sure what the "T" stands for but she definitely nips. Elizabeth says that I must smell like food to her. I think she wakes up grouchy. She's not afraid of Murphy which is why I think of the hamster, Rhino, from the movie, "Bolt" when I look at her. In her little hamster ball she runs around and goes straight for the dog. I think the hamster scares him too!
