A device and method for detecting and recording animal behavior is provided. The device includes an enclosure having first and second chambers, each of the chambers having exterior panels formed of an opaque material, at least one image capture device disposed in each of the first and second chambers, the at least one image capture device arranged to capture behavior data of one or more freely roaming rodents, and a first container insertable into one of the first and second containers and positioned below a respective image capture device, the container having one or more corrals into which one or more rodents are housed during testing, the container being formed of a transparent material. In some embodiments, the first container is formed of a red transparent material, the one or more rodents being unable to see through the red transparent material.

A ventilated animal crate (1) having a ventilation system (15) for circulating fresh air through the animal crate to prevent pets contained within the ventilated animal crate from overheating. At least one fan (37) is mounted in a top panel (7) and /or rear panel (5) of the crate and is connected to air distribution channel (30) in the top panel having air vents (40) for widespread distribution of air inside the ventilated animal crate. The at least one fan has at least one filter (37) to remove debris from the air.

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 durable feral cat shelter adapted to be inviting to feral cats year-round by having two entrances/exits for each compartment or sub-compartment, wherein each entrance/exit has a conduit of a predefined cross-section that protrudes a predefined length from the body of the shelter, thereby inviting feral cats while deterring most would be predators of the feral cats. Two or more feral cat shelters can be connected by a coupler that allows access to the connected plurality of feral cat shelters.

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 pet carrier-backpack for carrying small to medium sized pets, with abundant space, sun protection, ventilation, support, and comfort, with the emphasis being the placement of air ventilation and the shade structure that offers maximum functionality. My soft sided pet carrier backpack is a portable home for the pet with an abundance of strategic ventilation and space, with a removable/expandible shade for the pets' sun protection. My invention functions as a car seat also and offers the option of choosing between two head holes so the pet can be zipped all the way in the pet carrier and enclosed, laying down, or having its head out of the backpack, while its body is completely enclosed. There is a removable-sturdy, fur bed that detaches from the bag to allow your pet to lay on it anywhere you place it. The circular air vents on the front face of the pet carrier as well as the air vents on the left and right sides of the invention, create discrete as well as non-discrete usage options for experience, while maximizing air flow.

A cat carrier includes an enclosure, tray, grate, and latch. The enclosure has a front opening, and first and second holes. The tray is slidable within the enclosure, between extended and storage positions. The grate is joined to the tray, with a portion extending in proximity to the front opening of the enclosure when the tray is in the storage position. The latch has a handle, and first and second latch wires spring biased in opposite directions, with distal ends respectively received into the first and second holes, when in the storage position, to redundantly latch the tray the enclosure, so it cannot be undone by a cat housed in the carrier. The first and second latch wires each include finger graspable loops configured to be actuated by a thumb and forefinger, while pulling on the handle with the remaining fingers to single-handedly slide the tray out the enclosure.

A ventilation system for a housing structure with a plurality of air vents including: vent control modules configured to control and actuate opening and closing of at least one air vent of the plurality of air vents; an electro-mechanical drive unit mechanically coupled to each of the plurality of vent control modules and providing mechanical power thereto, the drive unit including a motor and a drive shaft, the drive shaft being disposed parallel to the axis of the air vents; a control unit, in communication with the drive unit and the plurality of vent control modules, configured to control the drive unit and individually control each of the vent control modules; the vent control modules use the mechanical power of the drive unit to individually effect the opening and closing of each respective vent of the plurality of air vents.

A generating device of simulating a particulate environment for an experimental animal includes an experimental chamber. An ultrasonic atomization device is installed at the bottom adjacent to the center of the experimental chamber. The upper side of the ultrasonic atomization device is connected to a guide device for guiding particles. The guide device includes an air seal cover, and a micro fan is installed inside the air seal cover to drive the movement of particles generated in the ultrasonic atomization device. Air guide pipes are fixedly connected to a side wall of the air seal cover. The generating device has good sealing performance, and can generate a variety of particle simulation environments to accurately and effectively simulate the biological effect of particles in the animal body. The generating device can improve the particle simulation environment, reduce the deviation of experimental data, and ensure the accuracy of the overall experimental data.

A cat carrier includes a tray, and an enclosure formed of: a lower housing portion with an upper mating flange, and an upper housing portion with a lower mating flange. Protrusions on one mating flange slidably engage openings formed with respect to the other mating flange, to releasably couple the housings together without tools. Holes in each of the mating flanges align, when the housing portions are mated, and each aligned pair of holes receives a fastener to releasably secure the housing portions together. The holes on one flange transition into a keyed opening (e.g. a hexagonal-shaped opening) that receives a hex head of a bolt, to prevent rotation of the bolt when a wing nut is tightened onto the fastener, permitting final assembly without the use of tools. The protrusions create a gap between the flanges, forming a track, which receives/guides a flange of the base.
