ABSTRACT:
There are more than sixty million cats in the United States according to the statistics of ABI Informer. My filtering system takes advantage of the facts that (1) air that has the odor of cats in it is slightly lighter than is air that does not have cat odor in it. (2) If air having odors in it are forced to change their direction of travel, the odor containing air will give up its odors. (3) Charcoal is an ideal substance to neutralize cat odors. Air saturated with charcoal will kill fleas, or make them to somewhere else to live. A perforated charcoal carrying tray, having an unperforated central area of approximately 10 to 15% of the area of the tray is positioned above the litter box, to permit the cat to use the litter box in the normal way, and wherein the unperforated central area forces the rising air to deflect its course to induce perimeter filtration, and wherein the rising air strikes the roof convering the charcoal tray, and is deflected back into the charcoal where the cat odor remains substantially dormat until the charcoal is changed. Most of the concentrated air will remain in the charcoal tray, and that the lesser concentrations will escape back to the area beneath the charcoal tray. A hooded doorway is provided for the cat to enter and leave the cat house, and the hood prevents the escape of odors to the home. Insofar as is known this is the only fully enclosed filter system that has been developed. This unit is unique because substantially no odor escapes to the home.
