Again---no expert here either. I did make a cat cubby set this past fall, on the edge of a Spruce woods, next to a grassy field. There is an ATV trail along the edge of the field, next to the woods. I had a piece of Christmas tinsel, silver color, hanging above the cat cubby. Beaver meat in the Cubby. Along the ATV trail, maybe, 50' from the cat set, I had a urine post set for canines. One morning, the cat set was ripped apart, meat gone, whole cubby destroyed, trap still set and still covered. Coyote tracks in the freshly disturbed dirt. In the urine post set was a Coyote. I will never know if it was "my" Coyote that ripped the cat cubby apart. What does seem clear is that the cat set flagging didn't scare the Coyote away from the post set.
