What does it mean if Maneki-neko is raising its left paw?
Statues of Maneki-neko, the “beckoning cat,” are often seen at places of business (especially stores). While it is often referred to as the waving cat, thanks to its lifted left or right paw (or both), the uplifted paw is not a greeting. It is believed that a lifted left paw is inviting or “beckoning” success in business, while a raised right paw is for protection at home.
