Sometimes our Feral Cat Trappers have a hard to trap cat and need something with a little more control than the standard wire trap.   The drop trap is a useful tool when conducting Trap-Neuter-Return—it allows us to selectively trap a specific member of a colony, since we can determine when to spring the manually-operated trap; and it is designed to help  trap cats who have caught on to the ins and outs of the humane box trap.   This is an indispensable tool for trapping feral cats.
