It depends on the cat and the leather. Last year we threw out the leather couch we'd had for around 3 years as it had large holes in it from the cats (the biggest was a foot in length!). We replecaed it with a leather one with tougher leather, cats are more likely to scratch soft leather. They still scratch the new one, but not as much. If you get a nice large new scratching post (one of them to climb on as well, the bigger the better) at the
same time, chances are that will be far more interesting. :)
