Christmas trees can be dangerous for cats, as they may try to climb the tree or chew on the needles. To keep your cat safe this Christmas, look for a tree that has blunt needles, such as a Douglas Fir or a Blue Spruce. You can also use a tree skirt to protect the bottom of the tree from cat damage, and make sure that any ornaments are secure and won't fall off easily. Lastly, make sure to keep any candles or other fire hazards away from the tree to prevent accidents.
