I have a male and a female glider and lately my male seems to be nipping at her tail.. he will chase her around the cage and bite the end of her tail.... is this glider fore play??

I didn't see any responses to your question yet (I only have a single glider so I'm unsure). I've seen a lot of other posts regarding biting and nipping so hopefully those were helpful to you. If I had to guess, I would say they're just being playful.

I have seen post about nipping their owners but not about nipping each other and that is why I was wondering if this is normal....

Is your male neutered? Just wondering if it was hormonal.

I actually "rescued "from a pet store back around Thanksgiving and don't know a lot about their past, I don't believe he is fixed and when I got him and her I was told she was pregnant, 5 months later I am beginning to think she Is just fat lol....
