Hey Currently I have my hognose on aspen. I have it about 3 inches deep and he loves to burrow. I just got him two days ago and he spends all his time burrowed. I was wondering if he will spend more time above ground once he gets acclimated? Also, what are some alternatives to aspen? Since they like burrowing so much what would make them most happy? I am guessing sand is still a no no even if I do not feed on it?
