Hard to advise, what size is "young boa"? (and by whose memory?)
Paper towels are fine as substrate, hide boxes can be cardboard temporarily if need be until you find what you want & need. (easy to make, also)
Don't keep as warm as for BPs...the BCI I had for many years often liked the cool side of her cage that was 72-76*. Like most snakes, they need warm &
cool side hide options.
Lucky boa to "find you"!![]()
