A circular cat litter container where a sieving mechanism is attached to a rotatable ring atop the container. The circular motion of the ring moves the sieve throughout the entire contents of the litter container capturing any solid waste that is too large to pass through the sieve. The sieve mechanism has axis of movement such that the sieve can be folded out of the way of the contents of the container when the sieve is not in use. The container and sieving mechanism are designed such that the sieve automatically moves into a scooping position when the ring is rotated in a clockwise motion. Conversely, when the ring and sieve are rotated counterclockwise, the sieve automatically is placed in an "out of the way" or resting position. The sieving mechanism is removably attached to the rotatable ring such that the sieve serves to act as a litter scoop to remove and discard the solid waste material found in the litter container. If desired the litter container can be made oval or rectangular with rounded corners and the ring can be replaced by a carriage moving along a track on the container sidewall and supporting the sieving mechanism. Also if desired, the container sidewall can be made non-continuous and the litter can be discharged through a gap into an auxiliary container at each end of its movement.
