The only time I was bit by a calm snake while handling it was when my daughter went to clean the girls tub and handed her to me to hold. I had just been petting our small dogs and I am sure the scent coupled with the heat signature of my hand in front of her, prompted the strike. Other than that, never. If you have small mammals, (cats, dogs, hamsters, etc.) just make certain the children wash their hands before attemppting to handle the snake. Have a great time with your new BP.
