We get baby snakes in our house. The first time we saw one, one of our first nights here, we were horrified that we had some sort of worm moving in to infest our food.
But we soon learned that they are snakes. They are babies. And they are harmless, even as adults. They are called house snakes, or serpent maison, and they apparently come in both black and green.
The cats love playing with them and they seem to be in endless supply so we let the cats have them. As long as the snakes stay babies and stay on the floor. I'm dreading the day I find an adult curled up in my t-shirt drawer, as nonvenomous as they are.
