Just some peace of mind would be great on this! I got Ollie for my glider jemma (he’s not neutered yet and is about 8 weeks old). And I did the whole pouch swapping for a bit with no issues. Ollie actually stopped sleeping under his tree stump and slept in the pouch with jemmas smell. So I put them both in the shower and let them sniff each other out and Ollie climbed into jemmas pouch and they just sniffed and sniffed! Once they were put into the bigger cage, there was some hissing and a bark here and there, with some nips as well but no crabbing or fighting. Is this normal/a good introduction? I have read that one will assert dominance and stuff too. Also, how old does the male have to be to try and mate? Cause twice it looked like he was trying to get nasty with jemma and climb on her back....but I don’t know if this is supposed to happen with new meetings? I don’t want baby gliders, but also read that if a meeting went well not to separate them after that. Any help would be great!!

sounds like everything went well.
is the new cage scent free?
If he was climbing on her back this could also be the showing dominance.
I would get the male neutered as soon as he is old enough. I would have kept them separate till he was neutered but best to keep them together now.
