Cats scratch as part of their natural behavior, but it can become problematic when your furniture becomes the target. The key is to provide alternatives like scratching posts or pads. Place these in areas where your cat already likes to scratch or near their sleeping spots, as cats often stretch and scratch when they wake up. Use catnip to attract them to the post, and offer treats when they use it. You can also use deterrent sprays on furniture or cover the scratched areas with double-sided tape to discourage further damage.
