We have a bunch of them and they are all still in the package! Never broke them out yet. Humphrey, our BP at night is always in his dried grapvine wood. He seems to favor being aloft. A few times in the morning before I go to work I check on them in their room and Hump is still there up there with his head resting on a branch either resting or fell asleep there! 95% of the time though he's back in his hide. I imagine he wouldn't mind even more stuff to climb about on if I put the vines in also.

So far as attaching them to the enclosure itself I'm stumped unless you ran wire through the ends or something to tie it off to the top somehow. I dunno though, like I said I haven't used them yet.
