This trap is designed with help from the "Neighborhood Cats" organization. The trap collapses to 36"x18"x4" for easy storage and transportation, but is easy to set up in seconds. This convenient cat trap allows you to catch wary cats with a simple pull of the string. Comes with a built on prop, easy release sliding door, and a weight flap to hold the trap in place. Drop traps are simply the most effective way to catch trap shy cats. (Does not include string)
