Now that’s possible. When it’s really dry here and the ground gets hard as a rock I can’t even see my own tracks much less anything else.
Don’t know how your weather is, but if I was just after cats and nothing else, I would clear snow or whatever I had to do to make a dirt hole set even if I had to use a pick ax. I’d clear a spot 3ft wide that could be seen from 100yds away and stuff enough bait down the hole to feed a pack of wolves. I’d have a set at the hole and another at the edge of the cleared out spot with urine.
I’m hoping you get it done!

I noticed of that cat tracks I found that they tend to walk in other tracks which makes them hard to distinguish. In my case they were walking in the tracks of wolves, coyotes, and coon. I only noticed the tracks when they eventually took their own path. If the snow is crusty I don’t think they will leave much of a track as the last couple I found were fairly faint in the 1/4 inch of dusty snow on top of the hard layer of snow. Even the coyotes were able to stay on top of the frozen snow.

How far are you traveling to find sign, set locations,how many sets are operating,etc. BR falls? I'd think there would be a good population east of town? Sometimes you have to go a little out of your way for the trophy. Boots on the ground as others have said will give you far more answers. Boots on the ground in locations stated will give you even more. Good luck

Best of luck to you AJE.
