I did some research before I got my gliders because I was thinking of breeding and if you are to get two males have two or more females because they will fight over mates but I’m not totally sure what happens when you neuter one of them, (I know some dogs become more docile and less “looking for a mate” stage when you neuter them but I’m not sure about sugar gliders). I hope this helps, please don’t take this as a for sure answer because I don’t have any experience with male gliders but good luck with your gliders!
