Keeping a cat away from the Christmas tree can be challenging, but here are some tips to help: 1) Keep the tree away from furniture that the cat can use to climb up to the tree. 2) Use a spray bottle filled with water to spray the cat whenever it gets close to the tree. 3) Place double-sided tape around the base of the tree to make it uncomfortable for the cat to approach. 4) Provide the cat with alternative toys and activities to distract it from the tree. 5) Keep an eye on the cat and redirect it away from the tree when necessary.
