In general, Christmas trees are safe for cats as long as they are kept away from areas where cats can access the decorations, such as ornaments and tinsel, which can be a choking hazard. Additionally, some cats may be attracted to the smell of pine, so it is best to ensure the tree is secure and stable so it doesn't tip over and cause injury to your cat. It is also a good idea to keep your cat out of the room with the Christmas tree while it is being decorated to prevent any mishaps.
