Catnip is a plant that contains a substance called nepetalactone, which has a refreshing, minty scent that can stimulate and excite cats.
Studies show that 50% of cats are sensitive to and interested in the smell of catnip, and will excitedly scratch and bite it. In daily life, if your cat is in a bad mood or unhappy, you can sew catnip into a cloth bag for your cat to smell, or simply place a small sprig of catnip near your cat's nose for it to smell, but it's best not to give it too much.
