Try this. I got this one plus the Kong incline cat scratcher. They are cheap and the same size. I have mine attached together.
How old is the cat? Sofa? And how long has the cat been doing this?
If it's been going on awhile, u may have trouble correcting the behavior and it might take more time.
If u have the time and/or this behavior has not been going on long, this could work for you:
My cat trys to steal your food, and I have a small spray bottle (got at Walmart in the travel sized stuff area for like $1) I purchased for misting plants. I've used it on the cat and she learned quickly not to try and take food.
If you're busy and/or this behavior has been a problem for awhile, a spray bottle might not do anything. I have seen scratchers made for sticking on the sides of furniture. I think this will encourage the behavior so I wouldn't recommend it.
