I love Martin's Cages. I have a 30x30x48 cage that is well furnished. I have a male and an expecting female in that cage. I plan to neuter the male and keep / neuter the joeys. Is this cage large enough? The only one larger is 30x30x60. Which is possible. I am not capable of making a pvc cage. I can hardly make a sandwich..haha. I do have an outdoor jungle that we play every night for 30 min to an hour.

From what I can find according to recommendations of number of gliders per/specific cage by it's size and given cubic ft measurements SunCoast Gliders (Thanks for that Lisa)

And using

this Cubic Ft Calculator by Inches

I see that your existing cage is 25 cubic feet (volume) which will accommodate 4 sugar gliders nicely. So you should be fine with it as the cage (Lrg. Sturdy) measuring 20 cubic ft (volume) can accommodate 3-4 gliders.

Thanks. If one day you see a story on the news about a crazy glider lady turning entire home into a glider cage it will be me...I got to win the lotto first.
