Jerry cleaned her cage (she had shredded a full trash bag of newspaper!) last night and put in clean paper, her foot toys, and a new box. As of this morning, she hadn't scratched or chewed or shredded anything. We were so disappointed! Couldn't figure out why. On our way home, I realized that the difference is that Jerry didn't put wads of newspaper in there. I mentioned it to Jerry and when we got home he put some in her cage. She immediately went down to the bottom and started scratching, tearing, and chewing! She wanted that wadded paper in there! I can't for the life of me figure out why, but she's a happy camper busily chewing on her box right now.
