Cats love to climb and explore, so it's no surprise that they find Christmas trees irresistible. Here are some tips to keep your cat from climbing the tree: * Secure the tree to the wall or ceiling with hooks or wires to prevent it from falling over. * Place aluminum foil around the base of the tree to make it less attractive to your cat. * Hang ornaments at the top of the tree and keep fragile ornaments out of reach. * Provide your cat with alternative climbing options like cat towers or scratching posts. * Spray the tree with a cat deterrent spray or use a motion-activated air sprayer.
