The invention relates to a pet toy that may be filled with food or scented material to attract and maintain the animal's interest while the pet tries to extract the material contained inside. The toy is preferably made with two nested housings with each housing containing one or more holes in the sidewall. Some of the holes in the housings may be adjustably aligned to create a opening in the side wall of the toy that permits materials inside the toy to fall out. The space between the housings is configured to trap crumbs or other particulate material that might create an undesirable mess if allowed to fall out of the toy.
