last year I had 2 small artificial trees on some end tables. They got knocked over every few days. I had no idea which cat was doing it. This year we have a very small, real tree sitting on the table (just some lights on it so far) and Toby doesn't pay any attention to it at all. I guess Havoc was the culprit, so I warned my parents that he may get into mischief if they put up a tree this year. My mom already laughs when she tells me he wants to play with the ribbons on all of the presents she's wrapped.
