well the caging is completely up to you, you can go extremely elaborate with live plants and underground hides, make a nice scrubland vivarium. that is definatly fun to design and set up, but it also calls for alot more intensive cleaning, i keep my thayeri in long, but low to the ground sterelite containers ( you can see them in the picture i included) i worked for a while in Vermont selling snakes and have dealt with many types of set ups, for me though, now that i have 8 snakes (soon to be twelve, thanks mike) the sterelite containers with a news paper bottom works best for me, i have never had much experience with thayeri as climbers, i have never really seen it, but i do offer obsitcles in their enclosures, be it rocks, vines, sticks, and various peices of cardboard boxes serving as a hide space and something to climb over or sit atop, i personaly feel it keeps them happier, i dont know why, but i do. If they do decided to crap on anything it is easily washed or just recycled in the card board dumpster. heating is pretty easy also with thayeri they dont require too much heat, if you read alot of the past posts it seems that everyone here keeps them between 75-85, 85 being the hottest it will get on the warm side of the tank, not in the whole enclosure. there are also two types of people that keep thayeri, ones that appreciate it, and others that are absolutley thayeri nuts, and you'll find both here. mostly nuts though. and over analyzing any snake purchase is the first step to success with the animal, so analyze away. hope this helps, if i missed anything hopefully someone else will pick up my slack.
