A system and method for an improved pet cabinet that provides an upper play area for a pet, a door panel opening leading to a litter box in a removable drawer, a sensor system to detect the presence of a cat, and a deodorizing system with deodorizing device, a filter, and a fan in communication with the sensor system.

A fan assembly for use in a sidewall of an animal house. The fan assembly includes an impeller, a motive force configured to rotate the impeller about a fan assembly axis, and a butterfly shutter. A shutter operation mechanism moves the butterfly doors of the shutter between the closed position and the open position in synchrony with an operating speed of the impeller. The shutter operating mechanism includes pushrods connected to the butterfly doors, and a linkage between the impeller and the second pushrods. The linkage includes at least one weight configured to rotate with the impeller about the fan assembly axis, wherein rotation of the at least one weight causes the linkage to exert a force on the pushrods to push the butterfly doors toward the open position when the impeller is rotating.

A disposable animal cage which can be used in a ventilated or static caging rack system includes a cage top and a cage base. Any corner or edge present in the interior of the cage base or the cage top that is accessible to an animal that can be contained in the cage is defined by surfaces having a conical section which is non-circular to prevent gnawing of the cage. The cage top can include a water housing mount pocket. The water housing mount pocket can have a conical shape to prevent an animal from gnawing the water housing mount pocket and a container received in the water housing mount pocket. A feed tray can be attached beneath a filter in a ceiling of the cage top to prevent an animal from gnawing the filter.

An arrangement and process of mitigating contaminants has a flow element intermediate a first space with contaminated matter (including contaminated gas) and a second space. Contaminated matter is drawn from the first space into the flow element and then urged into segregated contaminated gas and residual contaminated matter collected in the second space. Segregated contaminated gas is merged with gas from the second space to form mixed gas and treated to form primary treated gas which is directed to generate at least some of the drawing of contaminated matter from the first space into the flow element. Mixed gas can be treated by passing it through passages in the flow element coated with decontaminating agent and/or through a decontamination unit. The flow element allows for air flow to effectively act as a one-way barrier obstructing migration of contaminated matter from the second space back to the first space.

An enclosed litter box is provided that includes a housing sized and shaped for an animal and litter tray. The apparatus includes a self-closing door that impedes airflow between the interior and exterior of the housing and can be utilized by an animal as an entrance and exit to the housing. The apparatus further includes a recirculation ventilation system that includes a fan to draw air from the interior of the housing through a filter and then circulate the filtered air back into the interior of the housing. This filter is configured to remove odor from the air.

A livestock central air conditioner and a livestock house, relates to the art field of livestock house and equipment. The livestock central air conditioner including a heat exchange unit 1, a cooling component 2, an axial fan 3 and an air duct 4; the livestock house including a house 6 and the livestock central air conditioner; a ventilation fan 63 is provided at the location of the exhaust outlet 62 on the house 6.

A pet travel system includes a pet storage module and a closet within an interior cabin of a vehicle. The pet storage module has multiple module walls and a door that enclose a cavity configured to receive a pet. The pet storage module includes one or more first latch members attached to one or more of the module walls. The closet includes closet walls defining a compartment sized to receive the pet storage module therein. The closet further includes one or more second latch members attached to one or more of the closet walls. Each second latch member is configured to releasably connect to a corresponding first latch member to secure the pet storage module within the closet during a trip of the vehicle.

A trailer for transporting living fowl includes a first enclosure and a second enclosure that are separated by a partition wall, each of the first and second enclosures being defined by a top, a floor, the partition wall, a rear wall, a first side wall and a second side wall; an apparatus for generating conditioned air to be supplied to the first and second enclosures; the partition wall having a length extending vertically between the floor and the ceiling and a width extending horizontally between the first and second side walls; the partition wall including a plurality of fans being structured and disposed for creating a path of airflow of the conditioned air throughout the first and second enclosures; and a plurality of air supply ducts in fluid flow communication with the apparatus for generating conditioned air.

A system includes a container to enclose vehicles within a chamber, an enclosed structure to house a canine to perform odor detection, and an air duct positioned therebetween. The container includes a first door, a second door, and a raised floor. The raised floor includes a first ramp leading to the first door, a second ramp leading to the second door, and sets of vent ducts defined between an outer wall and a top wall of the raised floor, the sets of vent ducts to direct air flow upwardly into the chamber of the container. The air duct includes a proximal end located proximate to an opening within the top wall of the container, a distal end fed through the enclosed structure to a canine-sniffing location, and one or more fan to pull air out of the chamber and deliver the air to the canine-sniffing location within the enclosed structure.

Some embodiments of the present livestock structures comprise a floor, wherein the floor is configured to support livestock housing; a roof, wherein a majority of the roof is substantially parallel to the floor; and one or more supporting structures configured to support the roof; in some embodiments, the floor comprises a non-zero slope. Some embodiments of the present livestock structures comprise a passageway extending a majority of a distance between a first side and an opposing second side of the structure, wherein the passageway is positioned at an elevation that is below an elevation of the floor.
