The boa constrictor is a non-venomous snake that squeezes it's prey to death. Boa constrictors can make some good pets as snakes. The only problem is that: where are you going to keep a heavy snake that can grow up to 10 feet long? So for my opinion, don't get one.  Boa constrictors squeeze their prey so the prey can't breathe. Then the constrictor lets go and eats it when the prey is dead. Boa constrictors eat almost anything they can hunt.  Boa constrictors like to stay in wet, shady, and cool places. They don't have fangs, but they have sharp, curved teeth for gripping their prey.
