Scratching helps cats keep their claws sharp and healthy, because it lets them shed old claw sheaths. It also gives them a way to release emotions and relieve stress, and the movement works the shoulders, legs and back muscles. Scent glands in the paws leave a scent when a cat scratches, marking its territory.
Modern scratching posts come in many designs, often with tunnels, toys or catnip, which encourage play and exploration.
For owners, a dedicated scratching area can reduce damage to sofas, carpets, wallpaper and other furniture. Meeting a cat's scratching needs can prevent destructive behaviour caused by boredom or stress. Offering toys and scratching posts also shows care and helps build trust and a stronger bond, and a fixed scratching place keeps the home tidier.
