I have a male sugar glider and I'm saving up to get him a cage mate, only thing is idk if he is neutered. Is there anyway to tell? He is just a month over a year and has a very, very faint bald spot.

Mine isn't neutered and is under a year old... he has little fuzzy balls lol. I'm not sure if it looks much different after neutering or not. They are so small, so maybe consult with a vet and they would be able to tell for sure. Or do some research of your own online.
