Abstract: A circular litter box having a scoop removal remounted in a scoop holder which is pushed around the sidewall of the box to scoop the box. The mounting mechanism for the scoop causes the scoop to assume a relatively vertical position during scooping, to minimize formation of a wave of litter in front of the scoop as it is rotated, but causes the scoop to assume a more horizontal position as the scoop is removed, so the collected waste will not spill from the scoop during removal.

Abstract: 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.

Abstract: A method for making a decorative particulate material in which a clay based cat litter or other suitable particulate material is tumbled in a rotating barrel, sprayed with paint, and while the paint is wet, powdered mica is dispersed over the mixture. The adhesive paint adheres the mica to the particulates. Since only a single layer of mica adheres, the mica is used very efficiently. A clear gelatine-based top coat is sprayed over the mica. The finished particulates of mesh size 30 to 3 mesh, can be used in glass containers as a candle base and serve to contain liquid wax from the burning candle, preventing the wax from contacting the container walls. The resultant clump of wax and particles can easily be removed and thrown out.

Abstract: An animal litter, particularly for cats, in which a gelatin solution is sprayed onto the granules and a dry adhesive is sprayed through the gelatin spray onto the granules. The gelatin solution provides enough dampening to adhere the adhesive particles to the clay particles, but because the gelatin sets quickly, it does not provide so much wetting as to activate the adhesive. Therefore the adhesive retains its adhesive properties and, together with the gelatin, causes the litter to clump when wetted by an animal.
