Plus, we do not rely on our manicured fingers for exercise and protection. Phantom limb pain due to amputation is recognised in people, plus continued tenderness for years. Has anyone ever lost a fingernail? Ouch! Folks, get a dog if you can't deal with scratching. I still have furniture from looooonnngg ago, but get it reupholstered every 10 years or so. And not only from cat behaviour. Spilled milk, melted M & Ms, etc. Plus a spray to discourage inappropriate scratching places and a lot of scratching trees combined with treats.
