Well here is one snare set up I use in areas that I dont want to walk to more then once a week, it stays working in some of the worst weather too.
I start with two pieces of woven wire fence and make kind of a tunnel out of it like this.
And then I will hang a chunk of rabbit in it from the top, just so it will hang down and the cats can see it as the are checking it out, I didn't have it today when I went and built this for the pictures I just used a glove to show what I was talking about. This is what it would look like.
After I have the rabbit I will put in some good gland lure inside also, and after I have all the bait and lure inside I will cover it with pine or cedar bows, I have even used sage brush to cove them too when I was in big sage brush, heres what it looks like covered. Always make sure and cove the top real good, I have had some cats try to get at the rabbit from the top of it, so I make sure and cover the top where the rabbit is well.
Here is some pictures of it from up and down the wash, as you can see it has its own eye appeal, and then I will add some flags on the trees close to it just for more eye appeal.
Here is the way I will hang the snares, I put one on each end at the very beginning coming into the cubby.
I put in a stake right beside the cubby to tie the snares off to this is what I ues, I have also use trees to tie the snares off to also.
Here is what the finished set look likes when Im done, I believe you could do the same thing with traps at both ends too, I have never tried yet but have always wondered if it would work. I have taken several cats in these little cubbys over the years.
