<human>:  How can I prevent my cat from scratching furniture?
<bot>: One way to prevent your cat from scratching furniture is to provide them with plenty of scratching posts and other appropriate scratching surfaces. You can also discourage them from scratching furniture by using a deterrent spray on the surfaces that the cat is scratching, making them unpleasant for the cat to scratch. You should also regularly trim your cat's nails so that they cause less damage when scratching.
