Eleanor likes to nibble on my class ring, is it normal for chinchilla's to nibble on rings? I usually take my ring off when I have my hands in her cage, or during play time.
It's just something different, and they're interested. I always wear hair ties/rubber bands (silly bands!) around my wrist, and E likes to make a game out of going straight for them when I open the cage. He runs, bites, and flees! He's even won a few times.
My cockatiel was chomping on my ring when I saw a flash of something arc and flip away. I thought she had chipped her beak, but I couldn't see anything. Turns out she popped the big diamond in my wedding ring out, and it was not a cheap, easy to break setting, so be careful. You could try just turning the ring around in your palm while with them
