Also if the snake strikes at prey and misses, its teeth can get caught and it can pull teeth out which can cause infections. Someone on the forums had that problem not long ago. Plus I'm not sure how the carpet is easily cleaned as those things soak up piss liquid like a champ. I personally just use aspen and just throw it all out every month, Chlorhexidine down the cage, wipe it out and throw new aspen back in. And of course spot clean inbetween as needed.
