I say let the cats enjoy Christmas and help make family memories.
I remember when I was little we used to put the Christmas tree in the corner and string wire around the middle of it so the cat couldn't tip it over when he started climbing it or batting at his reflection in the ornaments.
In those days we didn't have a Christmas tree stand we used a galvanized bucket filled with rocks and water, the tree skirt was an old bed sheet draped around the base of the tree.
I remember that cat enjoying Christmas but I can't for the life of me remember what Santa Claus brought me that year.
