I found someone who is selling this cage for cheap, it is clean and seems her nice, also big. I was just wondering if anyone has this cage for their gliders? And is it safe for them?

It is called The Midwest Critter Nation Deluxe Small Animal Habitat (I couldn't get the link to work, sorry)

this one is model 161. I bought model 162. think the only difference is the extra bar at the bottom.
As long as its 1/2 bar spacing you should be good, I would also buy the DOUBLE stack for the glider.
We have 5 and have NOT had a problem with them.

I have this cage, and it’s Preety good. Spacious ( as long as you have the double). Overall, it’s safe and a good cage :)
