Abstract: The present invention is a pet training pad comprising a first end of a first conductive wire and a first end of a second conductive wire connected to a main controlling device, while a second end of the first conductive wire and a second end of the second conductive wire remain open. When a pet goes onto the pet training pad, the pet's foot makes contact with the first conductive wire and the second conductive wire at the same time, establishing an electrical circuit via the pet's foot. The main controlling device detects that the electrical circuit and then sends an electric shock current to the first conductive wire, thereby shocking the pet which will guide the pet to form a habit of not going to the position where the pet training pad is located.

Abstract: A live bait holder includes a flexible strip elongated from a first end to a second end. The flexible strip has a pair of edges extending from a first end to a second end and extending from a first surface to a second surface.
