<human>: What is the best way to keep a cat from scratching the sofa?
<bot>: The best way to keep a cat from scratching the sofa is to provide them with an alternative scratching surface such as a scratching post or mat. You can also try placing double-sided sticky tape on the sofa, which will help prevent your cat from damaging it. Additionally, you may want to consider covering up the sofa with a blanket or rug so that your cat has something else to scratch instead of the sofa.
