ABSTRACT:
A new pet doorbell apparatus for providing a door bell system for pets to use to notify home occupants of their desire to enter or exit the house. The inventive device includes cover cap activator attached to the outside or inside of a home. The cover cap activator includes a base plate and a enclosing cover pivotally mounted to the base plate. The enclosing cover is movable from a first position to a second position when the enclosing cover is depressed by a pet desiring to enter a home. When the enclosing cover is depressed, a transmitter mounted to the base plate is activated by an activator extending from the enclosing cover. The transmitter sends a signal to a receiver so that speaker included in the receiver produces a sound to alert a person within the home to let the pet inside.
