Hello , Whaf is a ideal cage size for four gliders, looking for a permante cage. I heard that bird cages are not. Good choice because there is more vertical lines and when they climb and jump the more horizontal lines is better, it goes with there more natural climbing and jumping branch to branch.
i'm also 100 percent critter nation / all living things(petsmart) cage sold. the large opening doors. and the stack ability. I have 3 cages stacked together with 7 gliders in it, so much room for them and all their toys and wheels. We have had the cages for 2 years and they still look brand new, no rust.
