Does your cat mess with your Christmas tree?

My family's kitten, Alice, is the world's worst about climbing the Christmas tree. She doesn't even get very far, perhaps a few branches up, before she gives up and lands back on the presents. Before this year, my family never really had to deal with cats and trees! So, this past Christmas was very different, but also extremely amusing. Especially seeing as our older cat, Sibyl, pretty much did nothing except watch Alice - even though we all knew that she was a expert tree calmer!
