Even my ground boas love to come down off their branches to attack their prey. I have even gotten non-feeders to eat by adding a few branches to the cage. Since most of these boas are bewteen 2-3 feet, large cages are not necessary. I use newspaper as a substrate for all animals. As with all boas, Candoia are mostly nocturnal.
All species have strong prehensile tails.
I feed my adults only 1 rodent every 3-4 weeks. During their winter cooldown, some specimens will go off feed. Some of my male ground boas may not eat for 6 months with no ill effects. The feeding of neonates is not as hard as you've all probably heard. Most baby candoia will not eat pinkie mice on the first attempt.
