There is only one solution I can see. Place the tree in a room with a door and keep the door closed. Do not allow the cat into the room.
Cats that play with Christmas trees can injure themselves when they knock trees over. They may damage property. If lights are plugged into the tree, the cat may electrocute itself or start a fire.
And, although the vast majority of cats make it through the holidays without incident, people with feline friends should be aware of a couple of other holiday hazards.
Ribbons on presents are tempting playthings for cats. However, a swallowed ribbon may cause the intestines to bunch together. The condition can be fatal without surgery. Ribbons and other so-called linear foreign bodies were discussed in a previous post on feline hazards.
Finally, if your cat likes to chew on plants don’t buy mistletoe, poinsettias, or lilies. All are toxic.
