This is a tough one too. Many of us see cute photos of gliders in shrubs and wish we could do that too.
First of all, as bonded as my Arwen is, I would NEVER NEVER NEVER take her outside at night. WAYYYY to risky.
As for daytime outside, they really wont enjoy it, as its daytime and they are nocturnal. I have had Arwen outside during the day, but not to play, more just to pick flowers for her. Which she loves. She has never shown an interest in leaving me, and just really wants to stay inside my shirt.
Too many risks having them outside. I mean a stray cat could come wizzing by and hurt them, there could be a slug on the ground they gobble up (and they will) and that slug could have any number of parasites. And what about mosquitoes? What if one bites them? Do they get heartworm???
There could be anything on the bushes you put them in that could be bad. In a tree??? ugh. they get startled and away they go.
She could go to chase a bug, get scared, disoriented, and take off and be gone
We had a hawk attack our duck within 6-10 feet of us, imagine an owl or hawk swooping down and taking your glider.
Too risky for me.
As for tents. We did buy a HUGE Genji tent just for outside use last year. I never used it, as I was too scared they would somehow break out and be gone.
