My mom is giving me her female sugar glider. She wants me to put her in with one of my pairs that I have. Would that work? And how would I go about doing this. It would make it one male ans two females in the cage then but my pair is very much in love with each other.

If the male is neutered it should be fine.

If he is intact then you could be in for some problems between the females. They could steal joeys from each other which might result in the death of the joeys.

Breeding trios often do not work unless the females are sisters that have always been together.

I wont do that then. Thank you so very much for the help.
