I don't mean to offend, but that's a load of poo right there. Not once have I over observed any on my leos getting their teeth caught on the floor. I've even got a female that will take a dive-for-life to grab a cricket and never had a problem.

I'll tell you why loose substrates are bad. First, male hemipenes occasionally come out for breeding purposes or for no purpose at all. They are very proned to becoming prolapsed if sand or dirt or bark gets stuck to that tissue. It can result in sterilizing your male or death from a resulting infection. Second, when they defacate, tissue within their vent can come out as well, resulting in a prolapsed cloaca. Again, a very serious conditions that's not fun to deal with. Third, loose substates pull moisture out of anything that contacts it. This include a vital area on leos- their toes. Stuck shed on their toes never gets a chance to come off and they end up losing toes as the tissue dies. Not life-threatening, but your leo can lose a few toes.

I'm not basing this on my opinion just cause- this info comes from personal experience with these guys and the observations i've made. Hope that helps.
