Sit Somewhere Else
Most people have a favorite spot on their couch. You might have sat there for so long that you’ve created a groove that fits the contours of your underside perfectly. But when there’s a cat in your home, your spot is no longer yours. You need to learn how to share.
Or, to put it more correctly, you have to learn to give up your spot on the couch completely. Your cat knows that you have a favorite spot and will do anything to keep you from sitting there. The best thing you can do is surrender your cushions quickly before they mark their territory.
