lol...if you count tree ornaments to be expensive you should have asked if your pets ruin things that are of sentimental value..Buster has ruined a ceramic bunny that my mom's friend gave me to me when I was 5 so I had to throw it away but I kept the bow for keeps that was on it and make sure he can't get it and Buster also chewed the nose off of my teddy bear I've had all of my life and the bow another time but I still have him..
