At what age exactly do female gliders start their cycles?

When I watch our girls having their TSK-ing matches I sometimes wonder if one (or both) are on their cycles.

I was just double checking their OOP dates. I have Astrid's for sure and I am asking for Tika's OOP date. Seems they are a little older than I thought. They are 6 months OOP.

What types of behaviors should I be on the lookout for to help determine if one is on her cycle?

Thank you again for being here for me.

Quick follow up on their ages... they both came OOP together at the same time.
So they are both 6 months old. No wonder they are so connected. Tika is always making sure she knows where Astrid is... at all times.

My girls had their first cycles at almost five months OOP. I only know because while my boys are neutered they did not realize it for a bit and would compete for who got first dibs and then would take turns. I took one of the girls out once as she was fleeing both of them because they kept pulling her around and she needed a break. Now that the boys are calmer it is harder to tell when they are in heat but I have my suspicions when the girls get bitey or there is a lot of hissing in the pouch in the evening before they get up.

I would say they start their heat cycles anywhere from 14 weeks and older. That is why it is important to wean the girls from their daddy's.

Do they have it when they are older, because I got my sugar gliders in July of 2020, and they were 4, and now they are 5, but I didn't know if they still get them or not.

6 months is about right. Heat cycles are every 28 days and last 3 days. My pair of girls made a hiss noise ending it with almost a 'ch' sound.

Yea they are both girls so that is probably why I don't notice when they get their cycles!
