Abstract: A pet debris trap catches items that result from traffic to a pet usage area, such as a cat litter box, or from a pet habitat such as a birdcage. In situations such as this, debris in the form of cat litter, feces, food particles, replaced feathers, etc., are deposited around the litter box or habitat. This presents a condition that requires constant attention by the pet owner. As a solution to this problem the present invention is a trap that includes a substratum that supports an adhesive, preferably a pressure sensitive adhesive, which is supported by, and positioned up away from, a base. This accessible adhesive catches litter that clings to the paws of a cat or droppings from a bird that would otherwise soil the bottom pan of the cage or bounce out of the cage and land on the floor nearby. The adhesive covered substratum can come in individual sheets or on a continuous roll, which can then be discarded when soiled and replaced with a clean sheet or section of the roll.
