The Christmas tree is just another toy for the cats. I think they believe I put it up just for them. Tigger and Eli mostly poke around the presents on the floor. It's a great place for them to hide and sneak attack one another.
Bows, on the other hand, is fascinated by the ornaments. I keep catching her pawing at them. To date she had broken two ornaments. Fortunately they're cheap and easily replaced.
