This invention is concerned with devices for controlling movement of small animals, of the kind commonly known as "Cat Ports". The device is activated by an operating magnet worn by the small animal, which when the animal moves to pass through the device, closes a reed switch. The reed switch is adjustably pre-biased by a positionally adjustable permanent magnet, to afford the reed switch with a desired sensitivity, and a control circuit includes a re-setting coil to return the reed switch to its open position after a predetermined time interval. The device may readily be modified to control movement of animals in either, or both directions, to and from a designated area.
A modular pet habitat specifically adapted to accommodate cats. The device includes multiple panels which are linked together in variable conformations to create a maze through which the cat can travel. Connectors that allow the user to snap panels together by hand, without the use of tools, allow easy construction and modification of the habitat.
A pet door for installation in an opening through a dwelling barrier with a frame having a rectangular portal therethrough in which an insulated movable closure is suspended to swingingly pivot intermediate the top edge and lateral midline of the closure. A resiliently flexible seal is mounted around the entire perimeter of the closure to sealably engage the rectangular portal of the frame. A selectively operable latch is carried on the closure to restrict movement of the closure within the portal of the frame.
A pet door has a frame member with a laterally-projecting tunnel formation together defining a portal through which a pet may pass. A flap is located in the portal for closing the portal, the flap being displaceable in one or other of two directions by a pet, to enable the pet to pass through the door in one direction or the other. The tunnel formation provides a ledge which confronts an adjacent opening edge of the flap when the latter is displaced in at least one opening direction, the frame member defining a step down or rebate which disposes the ledge sufficiently spaced away from the adjacent edge of the flap when the flap is displaced in the said direction as to ensure that a pet's paw cannot become trapped and jammed between the flap edge and the ledge.
A compact, animal-operated animal feeder is disclosed in which the feeder housing has a pair of foldable doors mounted over a feed opening and latched in a closed position. The doors can be unlatched by the animal, which carries a latch release device about its neck, and the natural tendency of the animal to push toward the feed will fold the doors laterally to an open position permitting access to food inside the feeder. A magnetic latch release assembly in which a plurality of permanent magnets are arranged in an array to provide a key for release of a latch having correspondingly arranged magnets is also disclosed. A compound door including a magnetically releasable latch assembly is also disclosed.
A pet door offering ingress or egress through a structural member. A lock mechanism in the pet door allows the pet owner to restrict ingress and/or egress as desired. The pet door features a dual control system that simplifies the setting of the lock. Each control corresponds to movement of the flap in one direction. The dual control system is also designed to be easier to access than a conventional pet door lock mechanism and to be less susceptible to unintentional adjustment resulting from incidental contact with the controls.
