Abstract

A false-detection prevention litter box is provided. The litter box includes a litter box main body, a supporting platform, a first supporting leg and a weighing sensor. The weighing sensor includes a connecting part and a sensing part. The sensing part of the weighing sensor is configured to sense a change in a weight of the litter box main body. The connecting part of the weighing sensor is connected to the litter box main body. The sensing part of the weighing sensor is connected to a first end of the first supporting leg. A second end of the first supporting leg is abutted with the supporting platform.
