Well they aren't box traps in reality. I use a couple of my hog traps that are 8x8 foot square with a roof and built like a fortress, the large size is not as intimidating as a box trap. As far as breeding season I see the bastards throwing a litter all year with no seasonal timing, probably because our cold season here is not as great like it was at one time. My wife has two cats (I hate cats) but to keep her happy the cats sleep on the back porch that is screened in. Last night a coyote attempted to get through the screen door I guess to dine on some kitty. I got a shot off at the him, heard a yelp and hope I wounded him.
