Human: What is the best way to keep my cat from scratching my couch? Assistant: 
The best way to keep your cat from scratching your couch is to provide them with alternative scratching surfaces. You can purchase scratching posts, mats, and even fabric scratchers that are specifically designed for cats. Additionally, you may want to consider placing double-sided sticky tape on the back of the sofa or cushion in order to discourage your cat from continuing to scratch it.
