also not all fleece is created equally. Some of the "cheap" $3 throw blankets can have edges that unravel and many times they have whip stitching around it that is also unsafe.
I ended using them cut up as cage pan liners for a while, until my gliders decided to try to pull them up thru the bottom grate.
When buying fleece the 2 kinds recommended by glider vendors as safe are the Blizzard fleece and the Anti-pill fleece.
The Polar fuzzy type fleece while cute and cozy for us, it unravels and is not safe for gliders.
Toilet paper rolls will absorb urine and have to be tossed regularly, especially if they chew on them. If you have aggressive chewers(like I do)I would not give any type of card board at all, the glue used can be toxic if ingested.
You can find some safe tree branches or apple wood sticks for them to chew/climb on.
I gave mine some eucalyptus branches and leaves and some crab apple branches off my trees.(no pesticides or any chemicals used on my trees).
I know it's fun to decorate the cages in themes but more so than decorations... your gliders need lots of toys to be active and stimulate their minds and keep them from getting bored. The toys get rotated in and out every few weeks and change the setups.
They are like small children that need to entertain themselves or they can get bored, depressed and take up over grooming.
They need a glider safe wheel for sure(or a tread mill like from fast track).
They like ball pits with pom poms or practice golf balls and ping pong balls in a basket to forage treats out of.
Vines and chain links hanging and as bridges to climb on, barrel of monkeys hung all over to carry and throw around.
Hanging foraging boats or bowls and baskets(like a toy box)for small floor toys.
I give them toddler bath squirters like rubber duckies and other critters, baby rattles and little girl plastic bracelets too. Weebles are a big hit too.
I have made some toys and cage name tags myself with rexlace/craft lace and pony beads and I have bought some from vendors too.
