Scratching is a natural behavior for cats. Cats scratch at ridged surfaces to shed the outer layer of their nail. With older cats, their claw sheathes don’t shed as easily compared to younger cats. This is why you see older cats lounging on their cat scratcher instead of scratching. This is how Cats use Cat Scratchers to Sharpen Claws.
If your cat is an indoor cat, there is probably not much opportunity for it to claw at objects which is why you might find them scratching at your couch or carpet. When cats scratch at carpet and sisal surfaces, they are actually scratching to shed away the outside layer of their claws. If you get a corrugated cardboard scratcher for them, ensure you get them a good quality scratcher so it doesn’t get shredded to bits in a few weeks.
The cat keeps scratching at the surface until the inner claw is fully developed and the outer claw is loose enough to shed. If you don’t provide them a surface to scratch at, they will end up destroying your furniture.
