Abstract
The wheeled litter-sifting cart is a device that is adapted to store containers of cat litter as well as to sift out used cat litter for disposal of waste and potential re-use of cat litter. The wheeled cart is mobilized via a plurality of wheels that are affixed to a cart frame. The cart frame includes a bottom deck, intermediate deck, and a top deck. The bottom deck, the intermediate deck, and the top deck are all parallel with respect to one another, and are equally spaced elevationally, speaking. The top deck includes a first opening adjacent to a second opening. A hinged sifter is attached to the top deck in between the first opening and the second opening. In use, a first bucket is aligned underneath the first opening, a second bucket is aligned underneath the second opening, and soiled cat litter is sifted via the hinged sifter.
