Yes, the throwing and skating of the Bone makes for much house ruckus against the hardwood floors, but she is panting by the time she is finished. It doesn't take much to entertain herself.
When the bone goes missing, we both notice it. It has been missing for a day. I have searched her toy basket, the upstairs, the downstairs, and under every couch. Nothing.
It surfaced today after doing a long overhaul on the underside of every couch. It just wasn't pushed slightly under the sofa, it was pushed rather far under; not sure how that happened. Perhaps Cora found a way to get her petite paw under the couch to get the bone to go farther. She is a plush toy gal, carrying them around and sleeping on top, never destroying a single stitch.
Excitement from the two legged and (one) four legged followed the finding. Cora, however, got Mr. Green (frog) and ran the opposite direction.
