A pet waste scoop, e.g., cat litter scoop, having a relatively large mouth opening includes body having an open end opposite a closed end and defining an interior therebetween for receiving pet waste for easy disposal thereof. A handle is integrally formed with the body and extends downwardly toward the closed end a predetermined distance such that the user may easily grasp the handle for manipulating the pet waste scoop while maintaining his or her hand a safe distance from the pet waste to be scooped. A plurality of elongate slot-shaped apertures that can be curvilinear are formed within a front surface opposite the handle for sifting the litter scooped with the pet waste scoop. The apertures are defined by a number of rounded elongate sifting bars that also can be of curvilinear construction and configured to prevent pet waste and/or litter build up within the apertures.
