Christmas trees?!? We put ours up on monday. That night, we had to lock the kittens in our room with us so that it didn't fall over (it is a 10ft tree). On tuesday, I left for work. Upon realizing that I forgot my cell phone, i turned around and went back into the house, and Ozzy was all the way at the top of the tree laying in the branches! Like it was no big deal! What a little punk!
