Color: Silver 12.5 x 5.5 x 4.5 inches live cage trap, humane way to catch, relocate and release rats, mice and chipmunks Larger trigger pedal than similar traps on the market, much more sensitive to be triggered Once the pedal is triggered, the door will be closed instantly and the auto door lock will prevent animals from escaping Easy to use and clean, reusable for indoors and outdoors Not applicable to big squirrels and opossums, since they have great power to chew through the wire or break the trigger mechanism inside.
