So i've decided instead of paying lots and lots of money that i don't have for a new tank for my 4 1/2 ft RTB, that i'm just going to build him one. Not the first cage i've built, however never one for a snake before.

Now a few questions. Is there any type of wood or anything i should be aware of that would harm him that i shouldn't use? I have a general idea of what i'm going to do, however i thought maybe some input from some other people who maybe have built custom cages, or have come across them could offer me some advice, or even those who have cages they've built would be willing to post some pictures. Still not sure how big i want to make it, but i'd like to give him plenty of room to climb and just be able to be active ( though i know they aren't always active ) i just want him to have that if he decides on it.

Any input or anything of the sort would be greatly appreciated..Thanks!
