I have moved my 13 months old male Dumerils Boa to his new big adult enclosure since a month. His new enclosure is 7,20 feet long, 2,60 feet deep, 2,60 feet high. So i provided him with a long tree branch to climb on. And he climbs it almost every night and spends hours happily on it. Who said Dumerils boas are terrestrial? False information
