By the way....this cant be IBD unless you have had him out around other snakes or you have been around other snakes and have not washed your hands. IBD is carried by Boa's. Typically if IBD is contracted by a BP....the fatality rate is quite quick....usually within 90 days at the most. Hence why we always push for a 90 quarrantine.
Also no carpet it breeds icky. lol
I highly recommend papertowels or newspapers. Super easy to clean and really safe for them.
