Abstract: According to one aspect, a litter scoop is provided that permits a user to take multiple passes with the scoop through litter having animal waste therein, without having to empty the litter scoop after each pass. In one embodiment, a rake portion and a receptacle portion of the litter scoop are separated by a lip arranged to retain the clumps of animal waste in the receptacle portion during reuse of the litter scoop. In another embodiment, a top edge of a receptacle of the litter scoop is located generally in a plane, and at least a portion of an inner surface of the receptacle that faces a proximal end of the receptacle is arranged such that a line normal to the portion of the inner surface of the receptacle is oriented at an acute angle with respect to the plane that is less than forty-five degrees.
