Predator Hunter,
I have had good luck with JS cottontail and an old Burnham Brothers grown cotton tale tape. They seem to respond to the higher pitched distress calls better around here. Another item I have had good luck with this year is the predator enticer decoy. It really holds there attention. I mainly hunt the cats in heavy cover and use a 31/2 12ga with winchester supreme 2 oz 4 shot turkey loads. I also start the tape at the lowest volume setting. I will usually stay on a stand for at least 30 minutes if I think I have a chance at a cat. But be prepared as I have had a couple respond in less than 10 minutes. Hope this helps and good luck!
