Thank you for your replies.
One of the reasons that I like this cage is because out of the space I have and where it would make sense to put it, this cage would provide the most space for the Gliders. If I make a smaller stand, remove the lighting on top, then I have a spot that would work well for this cage, otherwise I would have to go with a smaller cage and less room for the Gliders. I also like this cage because my cats wouldn't be able to reach through it. It seems like a nice cage but you do make a point about the cleaning, urine, and bar spacing.
Cats can't reach through
Has a pull out tray
Has wire for climbing
They say it's ventilated
If I were to buy new (don't really want to spend that much) they offer to customize the cage to your request, such as spacing in the wire and stuff
like they coat the wood
And it has a spot for food dishes
It may be ventilated but how ventilated?
Are there any coatings used that would hurt Gliders?
Placing things might be hard but idk
Glider urine might seep into somewhere and be hard to clean
How hard would it be to clean in-between the wire and the acrylic?
The default wire has a 1" spacing
Would it hurt for the Gliders to grab the wire?
The wire is on the sides, top, and I think bottom but not the back of the cage
If there is another reasonable Craigslist ad it's possible I could DIY it to try and make it Glider safe, such as the wire spacing, or I could diy the whole cage, I'd rather not diy the whole thing, but it is an option
