  • Patent number: 6684816
    Abstract: A pet areas mat for cleanliness where small animals eat, drink, are housed in a cage, or perform other functions, use of a litter box or litter pan. The mat is generally rectangular or oblong in shape and is constructed of a material that is absorbent on one side and laminated and non-absorbent on the reverse side, forming a moisture barrier. Stays are constructed on the mat by stitching, at various intervals, a binding to folds of the aforementioned material in a horizontal, vertical or concentrical pattern. The same binding is sewn on the perimeter of the mat. The stays and perimeter binding function to contain debris on, or in the general area of, the mat. The mat also absorbs liquids, the animal's drinking water and the animal's bodily fluids. The pet areas mat is very convenient for pet owners, as it is disposable and machine washable in cold water and must be air dried.

  • Publication number: 20020076348
    Abstract: This invention deals with a process for treating and sanitizing animal habitats. In addition to sanitizing the habitat the production of ammonia and odor from fecal matter and urine is inhibited or terminated. In the process an animal habitat is cleaned and subsequently treated with trichlormelamine (TCM). The TCM may be applied by spraying the habitat with a solution of TCM, by dusting the habitat with powdered TCM or by treating bedding/litter with TCM. This process produces healthier animals and as such the productivity of a given grow out is increased. The process of this invention is particularly suited to animal habitats which are used to raise batches of hogs, cattle, turkeys and chickens on a continuing basis. The TCM may be further incorporated into water soluble polymeric compositions which permit the TCM to be leached out in a controlled manner. Further the TCM may be incorporated into cellular and noncellular polymeric compositions which may be used as bedding/litter material, and cat litter.

  • Patent number: 5819688
    Abstract: A pet animal odor absorbing mat comprising a mat or pad formed of a fibrous material, such as a cellulosic material, and which is integrally incorporated with a zeolite mineral during the manufacture of the mat. The pad or mat is primarily based on the cellulosic or other fibrous material such as for example, wood fiber. The wood fibers are mixed with a binding agent such as an acrylic latex or other animal non-toxic binder, and the zeolite while in somewhat of a semi-viscous and semi-liquid state and then allowed to harden. The mat is highly effective for use as a bottom layer in cat litter boxes to absorb both urine or other wetness and highly effective, in literally entrapping odors, such as those odors arising from pet animals. The mat thereupon simultaneously releases oxygen. This type of mineral has been found to be particularly effective in removing those odors arising both from the animal urine, as well as other animal excreta.

  • Patent number: 5193488
    Abstract: A total system to remove, store and dispose of feline (or other animal) bladder and bowel movements through the introduction of and a complete utilization of many features and sub-systems to provide ways of operating and managing a fully sanitary method of wet and dry feline bladder and bowel excretions. The system encompasses a unique urine "purification by exposure to air process," via aeration. It uses the aerification process by having the urine go through a sand or other porous material in a top tray and then through a pervious bottom of said top tray, thence dropping on a suspended porous aeration tablet or pad. This produces an aerified urine. The process is preferably aided by special chemicals implanted in the aeration table which is multi-layered. This then dries the urine, producing no odor, and provides a complete, disposable, sanitary, odorless system of urine deposits.

  • Patent number: 5025752
    Abstract: The invention relates to the prevention of the odor caused by the action of bacteria on cat urine in a cat litter box. The cat liter box has a base and walls and is provided with a sorbtive-desiccant member for the collection of animal urine. Litter is in direct moisture transfer contact with the sorbtive-desiccant member. The odor prevention process includes the steps of transferring cat urine directly from granular particles, to the sorbtive-desiccant member, sorbing the urine in a sorbtive-desiccant member having high surface area and high urine sorbency, dispensing the urine quickly in said sorbtive-desiccant member, and evaporating said urine from said high surface area sorbtive-desiccant member through the granular particles. The sorbtive-desiccant member maintains the urine in a medium which subjects the bacteria in the urine to the effects of drying.
