Maggie is a cord chewer, so I haven't had a tree in about 7 years. I just replaced the cord to my livingroom table lamp last night. Thanks Maggie! Cleo likes to chew on the Christmas tree branches, so I figure...why bother?
Both my boys leave the tree alone for the most part. My RB buddies Miles and Taffy liked to climb the tree when they were kittens -- one year Miles almost gave my great-aunt a heart attack! She was walking past the tree, and saw two little gold eyes peeking out. Of course, my mom said, "Get your cat out of the tree!" They were always "my" cats when they misbehaved.
