Friend had a large snake, boa (I think), in his basement along with several tortoises. The boa was out of its enclosure to stretch. I leaned over and wiggled my fingers in front of it to get its attention.
"I wouldn't do that if I were you. I haven't fed him in a while."
Mine was a green tree snake. My Dad named him "Ralph". I never liked that name.. My dad built this huge cage with screening for it. Took up half of one of my walls. I'd catch and feed it crickets. There was one flaw in this system. Crickets, when not eaten in a timely fashion, will mate. The babies are small enough to pass through the screen. I had crickets chirping in my walls for a long time.
Ralph was a good snake. He'd let you handle him and loved to just sit on the chain above the dinning room light. Would sit there for hours. My parents would have people over and after a while would tell them to look up. For some reason, a lot of people left soon afterwards...
In his later years, he got a little more ornery. If he really didn't want to come out of or back into his cage, he'd bite you. Not a huge deal, but he did have a couple fangs that would leave a mark.
