The Weebles nibbles bites off when she eats. If you hand her an apple she will give it back to you when she is done with a dozen little tiny nibbles all over the apple. She does the same thing with celery and potatoes.
Yesterday the Peanut crawled between the sofa and the wall. We were afraid we'd have to move the whole thing to get him out.
While they certainly do NOT sleep during the day, they have been known to be wide awake half the night.
I'm considering looking into buying a large wheel for the living room so they can run off their energy in the afternoon....
