when I was trapping cats in minnestoa I used cubby sets (which filled right in with snow) and walk through sets with a staked beaver carcass. In wyoming I try to avoid the catch all predator set. I have very few non-target catches in my cat sets. I try to get them up off of the main trail. I have caught lots of big toms on a coyote flat set but very few coyote in a flagged cat set. The biggest problem I have is porcupines. If you are in an area with a buch of them you will catch everyone. Cats really seem to enjoy looking at them in a trap. I get pretty frustrated when I come up on a cat set with a porcupine in it and cat tracks all around him.

this dirt hole set took 5 cats in one winter and a badger. Not a single coyote. I just would not have thought this would turn out to be my most productive cat set that winter. That is just the way it works out some times. Not a single cat at this location in the past 2 years. A little drainage coming out of the timber on to a big sage flat. I think part of the issue is that are rabbit population crashed and the food just is not there anymore.
a couple of cats on drags in the timber.
