Hey I'm a new owner of two 6 moth old sugar glider an I need help my boy gizmo is opening his mouth really wide like he's gagging. I need help idk what to do or if it normal. I took him out an he was running all over me so his behavior was him normal self. Plz help thank you

I would call a vet right away or in the morning if you don't have a glider vet for after hours.

I have heard of this as a symptom of having something caught in their throat or a thread or a long hair wrapped around their tooth or tongue...

It definitely needs to be checked out by a vet.

Good luck and keep us posted.
