I have had my two sugar gliders for about two months now and I really need some advice on intros. They came from two different people so we did the 30 day quarantine and brought them to the vet, they are also around the same age. When they're together, they seem like they do like each other there isn't any fighting until they start to groom each other. It's always the same thing, Zeus will go ontop of Nala and start to groom her and after a little she looks annoyed and tries to get him off and they usually end up fighting, but I can't tell if it's serious fighting or not. Nala always tries to go ontop of him also to groom but I don't think he likes it because it's the same thing, after a bit they start to fight. They kind of go in a ball which I heard was bad, but they never crab, they're easy to separate and they aren't biting hard but i'm just scared if I let them go it will get more serious.
When me and my husband spend time with them we always bring them together to play so that they can get use to each other. Their cages are next to each other, at night i'll sometimes put them in the same cage and they eat fine with each other around and will play with no fighting or anything until they start grooming each other.. so i'm just hoping that someone can give me some advice on this.

Possibly they are trying to mate? Are they male and female? That sounds to me like it could be mating behavior.. Sometimes it looks like they are fighting, but really they are mating. I could definitely be wrong though.. I'm new to gliders, but have been worried about my gliders mating before he gets neutered (the are brother and sister so that would be badddd).

So, my glider, Luna, really needs a friend. Therefore I've been starting to do research on intros/quarantine. I obviously have no real life experience with this, and I haven't done nearly as much research as I want to, but what type of places are they in when they do that? A lot of the research/reading I've done says you should switch their sleeping pouches and stuff first. It's to let them get used to each other's' smells (they're so scent-oriented).

You mentioned that you will sometimes put them in one of the cages. Maybe they realize that the space their in belongs to one of them but not the other. Perhaps this wouldn't be as much of a problem in a neutral space? Like, completely clean the cages first. Or, I've heard people on here talk about using the bathtub as a neutral space. Perhaps you could try that? Or maybe a pop-up tent which is free from either glider's smell?

Ultimately, I'm really not sure how to interpret the behavior you're describing. I hope someone more knowledgeable can shed insight on the situation. I just wanted to share the suggestion of a scent-neutral space.

Mine do the same thing, they will sleep in a pouch together all day but once they wake up Apple seems to get more aggressive and ball up with Jax. I have been trading pouches, toys, fleece this whole week in an effort to get them both used to each others scent. It does seem to be working, I will know better after Tuesday when Jax gets neutered, but Apple has stopped making her hissing and chattering noises when I put his stuff in her cage.. so it looks hopeful. Good luck.

I have tried swapping pouches, bringing them into the tub or a bedroom where theres neither of their scent. The only thing I can think of why they're doing this is because they both want to be the dominant one maybe? The male isn't fixed, me and my husband were really hoping to have them breed just once to expand their family, then have him fixed right after.

If the male is no fixed I would say they are trying to breed also. How old are they? You will know if they are fighting. They make a lot of noise if they are really mad. Somewhat off topic, but if she gets pregnant, she cant get pg again while she is nursing you may end up with more than 1 litter and all male joeys need to be neutered by 12 weeks or they will breed with mom. Same for girls with dad.

They're both around 17 weeks old i think. I guess they aren't fighting then because they make no sounds when they're doing it, expect a hiss once in awhile.

I had 2, aged around 4, and we took in 2 others, aged around 1. All neutered males. After making sure they were healthy, I put the cages next to each other, and switched pouches fht first day. Second day, seperated the cages, but actually switched them in their cages. Left them like that. When I got up that Sat morn, I took my old ones when they were sleeping, and put them in the cage with the new ones. They have all been best buddies since them. I realize that I am lucky. All 4 of mine are laid back, but I just remained calm and tried not to worry too much. It went really smoothly.
