Definitions

  • the invention relates to improving and enhancing the devices and practices that are presently generally carried out in disposing of wastes, both solid and liquid, that are deposited by felines in the natural state of their living. These deposits are gene/ally made in devices from make-shift boxes to generally sophisticated but very impractical kitty litter boxes.
  • the invention relates to novel and improved waste elimination devices and systems for pet animals no mattfif whether they are felines or other pets such as small dogs or pet skunks, etc.
  • felines felines or other pets
  • the invention specification is described solely with respect to felines, but should not be interpreted as limited thereto.
  • the aim of this invention is to provide a complete and absolute dissipation of the urine through aeration by the method of employing a solid, suspended tablet or liner which is designed to collect the urine, which tablet also contains a chemical to instantly or quickly absorb and/or neutralize the urine through a chemical reaction so that no ammonia will appear or be generated or long linger; and in which said method the liner will serve to facilitate the dissipation and evaporation of the urine prior to the liner's next usage.
  • the liner can be used for one cat for one week or longer period and then is totally disposable, as it is biodegradable.
  • the litter box design involves two main compartments and a tray that suspends the liner and is removable.
  • the system can be used without kitty litter such as with light sand of appropriate particle size mesh or gravel; and, due to lack of bacteria pick ⁇ up, the sand or gravel needs to be replaced only about one/fifth or one/seventh as often as is generally practiced with kitty litter in most other systems or boxes.
  • the upper compartment tray is basically hollow, being only restrained or separated from the lower tray assembly by a pervious bottom of special design (preferred) or by a screen mesh, (preferably made of plastic), there is no build-up of urine impacted kitty litter as in other systems as the urine goes directly through the pervious bottom of the upper tray or through the screen and the particulate material on the pervious bottom or on the screen to the liner or tablet suspended in the lower tray assembly where it quickly or instantly is absorbed by or reacts with the chemical (s) in the liner, or tablet.
  • the non-absorbent particulate material (preferably not cat litter) which is all that is needed for stool.
  • the stool may be removed as infrequently as once a week or longer because there is little or no odor involved with dry stool, and the stool is dry because it does not sit in urine soaked litter.
  • the urine goes through to the chemically treated, absorbent tablet or liner. This is contrary to the wet, smelly and mushy stools presently to be found in kitty litter boxes.
  • this invention is designed for the containment of urine and wastes of the feline animal, in an odor free environment, that at the same time provides maximum sanitation and the containment of both urine and stool.
  • This system provides a total of several elements and features that combine to provide a simple method and apparatus of animal waste control along with a reduction of costs while at the same time reducing the necessary maintenance, and also while providing a unique and advanced sanitary cat waste elimination system.

Abstract

Système complet permettant d'enlever, de stocker et d'évacuer les matières fécales et les urines de félins (ou d'autres animaux) par l'application et l'utilisation optimale de nombreux éléments et sous-systèmes, ce qui permet d'appliquer et de gérer un procédé d'évacuation entièrement hygiénique de matières fécales et d'urines humides et sèches de félins. Le système comprend une 'purification unique de l'urine par exposition à un traitement par air', consistant à utiliser l'aération. Le système comprend l'utilisation d'un procédé d'aération consistant à faire passer l'urine à travers du sable ou tout autre matériau poreux dans un bac supérieur, puis à travers la base perméable de ce bac, après quoi elle tombe sur une plaque ou un coussinet d'aération poreux suspendu. Ceci produit une urine aérée. Le procédé est de préférence renforcé par des produits chimiques spéciaux implantés dans la plaque d'aération, qui comporte plusieurs couches. L'urine est ainsi séchée sans produire d'odeur, de sorte que l'on obtienne un système complet, jetable, hygiénique et sans odeur d'évacuation de l'urine. Les matières fécales se logent dans le matériau poreux sec où elles sont enterrées par le chat et/ou évacuées par le propriétaire du chat, ce qui réduit sensiblement leur odeur, puisqu'il n'y a pas d'élément maintenant l'humidité de ces matières fécales, le sable ou tout autre matériau poreux étant sec.
