Thank you for letting me know!! This explains why him feel very easy with snake as a pet! I used to have a friend who used to have a snake pet but he became loose from his cage.
I had to help him locating three little kittens inside his house. Then, later he told me his snake was loose. I was quite stunned that I could be looking for a medium size snake as well as those kittens! In the end, everything was alright!
