A feces and urine disposal device for cats includes a support structure having parallel, vertically extending wall members, a bottom chamber, and an elevated relief area between the opposing wall members and above the bottom chamber. The relief area includes a pair of longitudinal channels disposed in spaced, parallel relation to one another and an open longitudinal gap between the channels and communicating with the bottom chamber. In use, a cat stands in the relief area with the left paws in one channel and the right paws in the opposite channel so that the cat is straddling the gap. When the cat relieves itself, feces and urine pass through the gap and into a removable trough positioned in the bottom chamber or directly into a toilet bowl. Cat litter or another odor absorbing or containing substance can be placed in the trough, as well as the relief area.
