Cats have unique patterns on their noses, known as nose prints. Each cat's nose print is unique, just like a human fingerprint. Nose prints can be used to identify cats, just like a dog's collar and tags. Nose prints are made up of ridges and furrows, which can be used to create a unique pattern. A cat's nose print can be taken by pressing an ink pad against the cat's nose and transferring the pattern onto a piece of paper.
