Not so much 'making' one that's expandable (I don't think my construction skills up quite up to it

) but if I found a good tall one then just 'blocking' off some width with say a rock wall or soomething, maybe in half or something like that, then moving it out as the little fella gets bigger.
Also another quick question (sorry newtothis), with regard to the light cages, wouldn't they get hot enough themselves to burn the snake a bit if it touches it when they have a heat lamp inside?
