Ours has scratched the corner of the sofa to bits, she seems to sneak a scratch when we are not looking. I am not sure you can be an animal lover and expect a spotless damage free home :-( Those cats are lovely, ours too loves to sleep on the sofa but only when she can prop up her head on a cushion, thank-you-very-much. She seems to always like to have a pillow under her head!
