I've been having a problem also - I'm afraid to catch the neighbors cat if I use cat food - I've caught 1 raccoon, and1 possum. But now what ever it is came into my barn, in between my horses and
squeezed through an arrea about 3" x 1" and killed 2 babies that I had in a cage and tried to pull then through the wire. Today it got 2 more babies...
What kind of traps are you using?
