I've recently acquired a Colombian Boa and I know right now he's only looking for ways out but down the road, I'd like to put in something he could climb on, as they are semi-arboreal and will use them if given the chance. I guess, to sum up my question, is there anyway to make or put a climbing branch in a tub and still be stable? Could I get some ideas as well? I wouldn't mind doing a DIY project either, just need to be pointed down the right path (:
