Yep, sunglider said it.
That's what I do too. I wash all fleece except the pouch they are sleeping in and I don't wash the cage the same weekend, and I will leave one wall/side of the cage and not wipe it down...just the rest of it and it keeps it smelling like them and then the remarking of the cage is not a big issue for them.
For the bonding pouch I use their cage pouch usually and some times I will put it in a bigger pouch with a zipper so if they start to wake up and someone decides they want out, they are contained until I can get them back in the cage. (I have 4 dogs and a cat so I have to make sure they can not get loose or away from me.)
For catching them at the end of tent time...I bring in zippered bonding pouches and treats to lure them in there. I have had to zip one or two in a pouch while catching the others. Otherwise it's usually musical gliders in and out of the pouch.
You can also set a light timer to turn on the lights bright in the room where you are in the tent and play time is over, and they may dive into the pouch to go take a nap. I try to keep the lights really dim(or use a red light or light from the T.V.) so they are more active during play time.
Your gliders are beautiful! Congrats you guys are doing a great job!
