Hi, I'm not entirely new to snakes, I've handled them many times and taken care of them for a friend for a fairly long period of time. I've also owned leopard geckos, so I have a general idea of how reptile terrariums are set up. Recently, I've been looking into buying a kingsnake (Mexican black kingsnake, to be specific). Could someone give me some tips on what to buy as soon as I get him? First order of business is the terrarium/vivarium/cage/tank/whatever you want to call it. I've heard people say that snakes need about a square foot of space per foot of snake, and I'd rather get a large terrarium for my snake even as a juvenile than have to buy a new one in a few years. Since Mexican black kingsnakes get 3-4 ft long, that would be a 3-4 sq. ft terrarium. Approximately how many gallons is that? Also, substrate--is sand good for kings, or should I use aspen? It doesn't really matter to me, but what's more comfortable for the snake? Secondly, how often would I need to feed it (I know kingsnakes tend to be more ravenous than most other snakes)? I'll be feeding it frozen-thawed mice of the appropriate size and occasionally a live mouse or something else (maybe a feeder anole?), I hope that's okay. Also, are kingsnakes more prone to biting people than corn snakes? The snakes I mentioned earlier were corns, and I could hold them without the slightest fear of being bitten by them. Even if my king does bite me, I don't really mind colubrid teeth, but I want to let my younger cousins and family members be able to handle my snake occasionally and I don't want it to bite them. I've heard that juveniles bite more, which is understandable, and that once they learn that you aren't a threat they rarely bite at all. Okay, sorry for the long post, but I want my kingsnake to be happy and comfortable. Thanks in advance for any advice!
