A remotely activated door-opening mechanism is provided for a cage trap having an animal enclosure. A mechanism is mounted outside the enclosure of the trap and is preferably remotely activated by an IR or RF transmitter to open a door of the trap and release a trapped animal when the operator is at a safe distance away. The mechanism may also be manually set with a time delay and may be associated with either a main entry door to the trap or with a secondary escape door located at an opposite end of the trap.
