I went out to the lease a couple weekends ago and tried out a theory I've been working on. Sounds funny but you know the animal toys with the squeeker built in them. They drive dogs and cats crazy so I thought why not try to call some coyotes in with one. Our lease has lots of coyotes and a good population of bobcats. I set up in three different places and called in 5 bobcats and two coyotes. I only shot at the coyotes and I believe I called in some of the bobcats twice, they were youngsters in the 20 pound class. The neat thing was how fast these animals reacted and came on the run. Definitly worth a try for any varmint caller.
