Yikes! Eudora sounds like quite a handful! My other cat Nemo was a bit wild when I first got him, but I think it was because he too wanted a playmate, and fortunately his brother and littermate Gianni was still at the shelter, so I adopted him too. I'm glad they have each other to terrorize now.

Did you ever get the painting restored?
