Yeah. I used to do the silk vines from Michaels craft store but my snakes pull the stuff down and then poop or pee on them. And then I am stuck with silk leaves that smell like snake poop. I mean even hanging them in the shower and spraying them down with F10SC, letting them soak and then rinsing them off doesn't really get the smell out lol. I gave up and now just give all my gals and guy hides and a water bowl and of course the shelf. They seem fairly content. All really mellow, eat like horses, poop like horses and growing.
If I had display snakes like GTPs or ETBs, I would definitely set up a sweet cage with tons of perches and vines hanging down and even maybe one of those Zoo Med waterfalls. Give it a total jungle look to it but those snakes I probably wouldn't "play" with as much as my boas or retic. I mean my boas come out with me in the summer at least 3 times a week if not more and the retic will be getting that too so having a really cluttered cage would just make taking them out a pain and trying to find poop and pee a pain. Not to mention, I have enough work cleaning out 6 snake cages every month. Couldn't imagine having to do that as well as washing all the decorations for 6 cages. Would take me a weekend a month to do it lol.
