A pet door has a frame defining an access aperture with a pivotally-hung aperture-closing flap therein and with a catch to secure the flap against opening in one direction. The catch is supported on a collapsible support, and a pivoted lever is normally positioned to prevent collapse of the support whereby the catch is maintained in a flap-securing position. The lever bears a freely-rotatable elongate magnet which is co-operable with a key magnet on a pet collar, and when the key magnet is presented to the pet door, it attracts the magnet on the lever causing the lever to pivot to a position giving the support freedom to collapse and permitting the catch to be moved from the flap-securing position.
A pet door with a frame defining an access aperture and an aperture-closing flap pivotally mounted therein, wherein the pet door has latch means to bar the flap from opening in at least one direction and control means for disabling the latch means to permit the flap to open in said direction, the latch means comprising a catch and a collapsible support normally arranged to maintain the catch in a flap-barring position, and the control means being magnetically-responsive and operable, when a magnetic key means is operatively juxtaposed with the pet door, to allow the support to collapse and enable the catch to be moved from the flap-barring position to permit the flap to open in said direction, characterised in that the control means include an elongate magnet mounted to rotate freely about its major axis.
