One day my colleagues gently gave me a rat. 30 generations of selection for benevolent behavior. I have had various rodents all my life. There was no such devil before or after. It destroyed any cage, intimidated the cat and entered into a criminal conspiracy with him to steal food. Filming eggs and eating stolen cream with a tail were almost a daily practice. In the hands was reluctant, the guests were bitten by the heels. Demonically sitting on the window (living on the first floor) and frightening passers. Generally speaking, I now better represent the model of domestication. Yes is. It is :)
