Please help, my glider is acting strange
Hello, I love my sugar glider and I have recently noticed a pretty startling habit of his. Whenever I take my glider out of his cage and he is put on any fabric, he will bite it constantly. I had a blanket that I put over the cage so the gliders won't get bothered by the bright light during the day, and when I take him out and put him on the blanket he would bite it. I didn't think it was a big deal because it didn't harm anything, but now when he climbs on me, he will get up to my shoulder and bite my shirt and he will bite me through it. Yesterday he started biting the metal cage, which is probably damaging his teeth.
He has plenty of toys and perches that he can chew on, but he doesn't. I am worried that he might start biting his sister.
