A door assembly includes a frame having interconnected wires that define an opening for an animal to pass therethrough, and a door having interconnected wires and being coupled to the frame. A latch assembly has a handle structure and a pin. The handle structure is pivotable with respect to one of the door and the frame, and the pin is movable axially with respect to one of the door and the frame. A first wire of the plurality of wires of the frame forms a key hole assembly. The key hole assembly defines an aperture for receiving the pin when the door is in a latched position with respect to the frame. A tab assembly is formed by at least one wire of the door and is disposable behind at least one of the plurality of wires of the frame in the closed position.

A door assembly for an animal enclosure includes a frame having a plurality of interconnected horizontal and vertical wires that defines an opening for an animal to pass therethrough and a door having a plurality of interconnected horizontal and vertical wires and being coupled to the frame. The door is disposable between a closed position and an open position. A latch assembly is coupled to either the door or frame, and removably couples the door to the frame in the closed position. A blocking member is coupled to the door and located between at least two adjacent wires of the plurality of interconnected wires of the door. The blocking member is disposed adjacent to the latch member such that a portion of the latch member is in contact with the blocking member in a rest position.

A pet carrier assembly, including: an upper cage housing; and a lower litter pan coupled to the upper cage housing; wherein the lower litter pan is detachable from the upper cage housing and includes a removable waste grate disposed in a bottom portion thereof. The upper cage housing includes a hinged door structure operable for providing access to an interior portion of the upper cage housing. The upper cage housing includes one or more window grates or arrays of holes operable for providing ventilation to an interior portion of the upper cage housing. The pet carrier assembly also includes one or more coupling mechanisms for coupling the lower litter pan to the upper cage housing. Optionally, the pet carrier assembly further includes a moisture absorbent material disposed between the removable waste grate and a bottom of the lower litter pan.

A window-mounted pet litter housing is described. The housing is equipped with at least one door, a front opening, a transparent rear panel, a ceiling, a floor, and at least one window anchor mount. The front opening facilitates access to the housing by the pet. The interior of the housing provides adequate space for the pet litter box, as well as space for the pet to lie down and peer through the transparent rear panel. Vented louvers are disposed in the left wall and right wall which provide ventilation while preventing rain and snow from entering the housing. A mounting plate present in the preferred embodiment expedites and facilitates secure installation of the housing from inside the structure equipped with the window.

A ventilation apparatus for ventilating a building. The ventilation apparatus comprises a casing comprising: a cavity for housing a removable heat-exchange cartridge; a service door providing access to the cavity; a primary and secondary pathways fluidly connecting the inside of the budding to the outside of the budding, wherein the primary pathway and the secondary pathway cross the cavity along about perpendicular axes; a primary ventilator for forcing an airflow in the budding through the primary pathway; and a controllable secondary ventilator for forcing a controllable airflow through the secondary pathway. The ventilation apparatus, when the casing houses the heat-exchange cartridge, has the primary ventilator forcing an inflow of air through the primary pathway, and (ii) the controllable second ventilator for controllably forcing either an outflow or an inflow of air through the secondary pathway. The ventilation apparatus, without heat-exchange cartridge, has only inflow(s) forced through the pathway(s).
