<p>An adapter device for providing forced air ventilation to a litter box having an upper vent location, this adapter device comprising a housing member of generally rectangular configuration having a lower portion, an interior portion, and an upper portion. An external duct fitting is mounted upon the upper portion, and a downwardly dependent skirt member extends continuously around the lower portion. An internal duct extends upwardly through the lower portion of the housing member, through the interior portion, being connected to the external duct fitting located on the upper portion. An electric fan is located in the interior portion and operatively mounted in the internal duct, with electric current being supplied to the fan, so that it can selectively be caused to rotate and cause air from the litter box to be pumped upwardly through the internal duct to the external duct fitting located on the upper portion. A flexible hose is connected to the external duct fitting for delivering the air to a remote location. This adapter device, when the downwardly dependent skirt is placed over the upper vent location of the litter box, causes air to be removed from the litter box and to be delivered through the flexible hose to the remote location.</p> |
