All 4 of them are fit in the feeder.
Of course there needs to be more climbing structures, that can be easily done...
The gliders are quite tame, they're handled and hand-fed daily so don't bite. Young ones started to glide recently.
Currently, only young male (1 of offspring) resides in this cage.
His parents are separated, male was moved to other zoo and sired offspring with another female: http://www.zoochat.com/2226/sugar-glider-cage-411170/
