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.

What cage size and width is better thank you !

Bird cages are fine for sugar gliders.
My number one seller on my site is the Super Roomy Cage. Critter Love® Cages

Thank you, I am glad to know that so much mis information on the net, it's why I love this site. Thank you again

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.

Thank you very much I am really glad to get ideas and what's good cages thank you
