<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 plenty of alternative scratching surfaces such as cardboard boxes, sisal mats, or even fabric covered furniture. You can also try covering the sofa in double-sided sticky tape or double sided carpet tape, which will make it less appealing to your cat. Additionally, you can use deterrent sprays or spray-on products that contain an unpleasant smell cats find unpleasant. Finally, if you have multiple cats, consider dividing up the sofa so each cat has their own space and can't reach the other one's territory.
