Cats have the natural urge to scratch for a few reasons. It’s a good way for them to file their nails and keep them tidy. Cats also have scent glands in their paws, so scratching is a way for them to mark an area. Scratching is a habit they indulge in when they get excited or want to communicate. They may scratch as a greeting or as a reminder that dinnertime was 5 minutes ago.
Scratching can help cats burn off excess energy and aids in their well-being. Your cat will find something to scratch whether you have a post or not—so it’s best to give them a designated place with satisfying materials, like cat scratchers or towers. If not, they may pick your walls or your furniture.
