Abstract

See full text

A door knocker for use by a cat for requesting entry into a house. This knocker comprises a mounting block attached to a door surface; a longitudinal spring having a first end mounted to the mounting block and a second end extending vertically downward from the first end. A hardwood ball is mounted to the second end. The ball is held at a knocking distance from the door surface. A string with loose frayed ends is attached to the second end of the spring near the ball. A cat coming near the door knocker is attracted to the string with frayed ends and instinctively starts to play with the string to operate the door knocker into a series of repetitive door knocks. The door knocker according to the present invention does not require any significant physical or mental effort from a cat.
