Eloise dug this piece of foam rubber out of the closet and brought it up onto the day bed. She pulled bits off of it, and they stuck to her fur then got scattered all over the house. She also shredded a brown paper sack and bits of it started showing up all over the house, too.
The other day we went out to dinner and left both cats inside the house, the first time we weren't there to intervene if they started fighting. We didn't know what to expect when we got home, but both of them on the same bed had not crossed our minds. I think Eloise just wanted to guard her spot.
Chitty is not bothered. She likes taking over Eloise's favorite spots.
