Hello so my male glider keeps bitting everything an rubbing on everything around him. He even gets on the females back an had made a bold spot on the back of her neck. He even bites on the young glider as well. Can someone please help me I tried google an I can't find anything.

If your male is still intact that could be why. Especially if there are male babies in the same cage. From my research (Still a novice sugar glider owner)I have found that the males can be very territorial when intact. Maybe there is a "threat" to him making him react in such a way. Sorry if this doesnt help.
