To provide a toy-having cat nail polisher in which a cat himself has an interest and with which the cat himself can play and polish his nails, because most of present marketed cat nail polishers have only a function for polishing the nails and to not give such interests to the cat that the cat wishes to approach the nail polishers, although the cat has a habit scratching a furniture, a sofa, a carpet or the like in a room, when the nails of the cat grow.

This nail polisher utilizes a habit that a cat highly sensitively reacts to a moving article. Therein, the simplest principle of a seesaw is applied. When touched with the hand of a cat, a character 3a escapes. The head of another character 3b appears from the other place. While the cat touches the moving characters, the movements can semi-permanently be repeated without using any power.
