A cat litter box cleaning system designed to sieve waste clumps from cat litter is provided. The cat litter box cleaning system has multiple layers thereby providing multiple cleaning operations. The layers may consist of a sieving layer and a liner. The liner shields the sieving layer from the cat's claws and the sieving layer is used to remove the waste from the litter. Each sieving layer and liner releasably cooperates with layer securing fixtures. The layer securing fixtures releasably attach the layers to a base and prevent the cat from dislodging the sieves or liners. Access ports may be provided for removing the layers from the layer securing fixtures without having to come into contact with the cat litter. A method is provided where at least two cat litter box cleaning systems are utilized to ensure that fresh cat litter always forms the basis of the litter used.

1. A cat litter box cleaning system (100) for hygienically removing waste clumps (20) from a plurality of litter granules (10), comprising: (a) a solid base (110) having a granule contact surface (118), a base perimeter (120), wherein the base perimeter (120) has a wall (121) extending substantially perpendicular from the granule contact surface (118) to a wall height (129);(b) at least two posts (113) having a securing fixture height (116) and a cross section (114), and wherein the posts (113) and the wall (121) cooperate to form an access port (134) that receives a portion of the first sieve (140) such that an owner may release the first sieve securing receptacles (142) from the posts (113) and remove the first sieve (140) without contacting the litter granules (10), wherein the posts (113) are free-standing of the wall (121) and are attached to and extend substantially perpendicular from the granule contact surface (118), the posts (113) located within the base perimeter (120) and spaced from portions of the wall (121) nearest the posts (113) by less than about ¼ inch;(c) a first layer having a first sieve (140), wherein the first sieve (140) has at least as many first sieve securing receptacles (142) as posts (113), a first sieving surface (148), a first sieve bottom surface (149), and a first sieve perimeter (150), wherein the first sieve perimeter (150) is substantially the same as the base perimeter (120), the first sieve bottom surface (149) is adjacent to the base granule contact surface (118), and the first sieve securing receptacles (142) releasably cooperate with the posts (113), the posts (113) passing through the sieve securing receptacles (142); and(d) wherein the waste clumps (20) are separated from the litter granules (10) by (i) releasing the first sieve securing receptacles (142) from the posts (113), and(ii) removing the first sieve (140) so that the litter granules (10) pass through the first sieve (140) and into the base (110) while the waste clumps (20) are retained on the first sieving surface (148). 2. The cat litter box cleaning system (100) of claim 1, wherein the first sieve (140) further includes a first sieve gripping extension (160), wherein the first sieve gripping extension (160) is configured to be received within the access port (134) to provide an owner with gripping access for removing the first sieve (140) without contacting the litter granules (10). 3. The cat litter box cleaning system (100) of claim 2, wherein the first sieve gripping extension (160) is a first sieve gripping extension tab (162). 4. A cat litter box cleaning system (100) for hygienically removing waste clumps (20) from a plurality of litter granules (10), comprising: (a) a solid base (110) having a granule contact surface (118), a base perimeter (120), wherein the base perimeter (120) has a wall (121) extending substantially perpendicular from the granule contact surface (118) to a wall height (129);(b) at least two layer securing fixtures (112), wherein the layer securing fixtures (112) are posts (113) having a securing fixture height (116) and a cross section (114) that includes a concave portion with a first terminating end (114a) and a second terminating end (114b), wherein the posts (113) are: (i) attached to and extend substantially perpendicular from the granule contact surface (118);(ii) located within the base perimeter (120); and(iii) free-standing of the wall and spaced from the wall (121) nearest the first terminating end (114a) and the second terminating end (114b) by less than about ¼ inch;(c) at least two access ports (134), wherein the access ports (134) are formed by the cooperation of the posts (113) and the wall (121) and the access ports (134) are defined by a partially bounded area (135) between about 0.6 square inches to about 1.5 square inches;(d) a first layer having a first sieve (140), wherein the first sieve (140) has at least as many first sieve securing receptacles (142) as posts (113), a first sieving surface (148), a first sieve bottom surface (149), and a first sieve perimeter (150), wherein the first sieve perimeter (150) is substantially the same as the base perimeter (120), the first sieve bottom surface (149) is adjacent to the base granule contact surface (118), and the first sieve securing receptacles (142) releasably cooperate with the posts (113)), the posts (113) passing through the sieve securing receptacles (142) such that a portion of the first sieve (140) is within the access ports (134); and(e) wherein the waste clumps (20) are separated from the litter granules (10) by (i) grasping the portions of the first sieve (140) within the access ports (134) and releasing the first sieve securing receptacles (142) from the posts (113), and(ii) removing the first sieve (140) so that the litter granules (10) pass through the first sieve (140) and into the base (110) while the waste clumps (20) are retained on the first sieving surface (148).
