I have a leather suite and two cats they do not go well together you can by a repellant which will make them go elsewhere to scratch a scratch board will help ask at your local pet shop they are very helpful
You're lucky, wiggal-I've got 5 cats and a lovely leather chair. At least, it was lovely, till my two youngest got to grips with it!! Ah, well, at least now its got a bit of "character" (that's my excuse for my kittens!!) Love 'em to bits!
