Thank you everyone for your answers!
I was asking because I was told by some that my cage wasn't big enough for my 5 gliders much less 6. My cage is a 2 ft wide, 5 ft tall, & 2 ft deep. I have read in MANY places that each gliders needs 2 cubic feet of space (of course taller over wider), my cage is 20 cubic feet so I thought it was fine.
I can see my cage is fine comparing it to ya'lls, but I think I'm going to go ahead and get/build a bigger one when I can anyway lol. If I build it it will be 3ft wide, 5 ft tall, and 3 ft deep or 45 cubic feet.
The reason I didn't originally just build the 3x5x3 is because I would have had to order the materials instead of picking them up and I had never thought I'd have 6 beautiful gliders lol.
