In my ongoing quest to successfully trap, neuter & release the difficult, tricky characters out there in the feral streets of America, I have been working to create an inexpensive and simple to fabricate (advanced skills are not required), remotely triggered TomaHawk (having a 'guillotine' style rear sliding door) metal kitty trap.
I've attached a few photos to show the trigger assembly of my remotely triggered trap. The user holds a two button wireless key-fob, which can control two different traps. There is also a four trap version, 2x more expensive. Each remotely triggered trap, excluding the trap cost itself, is around $30 ea and using a Philips screw driver, a crimper and a pair of pliers, a remotely triggered trap may be assembled in roughly a half-hour.
The push-button key-fob can be located upwards of 50 ~ 75 feet distance from the traps. I place my traps out in the backyard (to catch opposums and-or racoons...eats colony food), and watch the trap through a window, or from the convenience of my car when trapping feral kitties on a street, to both watch and to prevent trap theft.
If anyone is truely interested I'll post a descriptive 'tutorial' about where to procure the components, and how to assemble your own trap.
