I haven't done much trapping for 35 years, seems making a real living and traveling the world has taken me away from what I enjoy, but now I have problems with semi wild house cats which use the flower garden as their litter box, makes it hard to open windows or the door for ventilation. My wife likes california, the last I heard steel traps had to have a pad on the jaws, and may even be outlawed, I can't use anything like that or even a snare, which might injure them, so I got a box trap, but I'm getting possums and other stuff in it. I need to know how to get cats in it, with out bait which attracts other animals. Anyone got any suggestions? Thanks.
