I'm switching to a rack system. I a.) have too many snakes not to b.) am sick of dealing with the crappy locks on my snake's cages getting stuck c.) don't make the cages look all that nice ANYWAY d.) want something that takes up less space and makes it easier to harass my snakes that doesn't involve clips/keys and locks/ and messing with putting a lid somewhere so I can kick it around and bruise myself. It just sounds easier and the humidty and temps fluxate where I live enough that something that is pretty stable sounds AWESOME! I've tried pretty much everything and had the lest problem with plastic tubs and my snakes shed wonderfully in them.
