That's the hamster-rodent in our domain. She is nocturnal, so you see absolutely no activity at all in her cage, unless you happen to be up late or early (like me.) When that happens, you are likely to see her engaged in one single activity: running on her wheel.
Heck, I can be in the kitchen eating in front of the boob-box, and what do I hear, but the, "squeak, squeak, squeak..." of Nibble's wheel going round and round eternally.
I think I'll take on a new nickname--"Nibbles." Why?
1) I admire the way she just keeps spinning that wheel (she has to be in great shape.)
2) I like to nibble.
(This forum is called, "Foo," isn't it?)
