Make sure you keep an eye on it.

I'm not sure if there is different types of boa's but this guy had one that was huge, had lived with him for years. Anyways, it was in the paper, but it quit eating, so he phoned the vet and they said, no worries, animals tend to do that if they're not feeling well, just keep an eye on him and call us if it continues. So the guy woke up the next morning and his boa was stretched out beside him stiff as a board. So he calls the vet again and tells them what happened, they tell him to bring the boa in immediately because he was sizing up the guy to eat him.

Hahaha, pretty wild, but word, watch out.
