Never had a cat show up that I saw, but I had one show up coyote hunting once. I had a tag for it but I was so shocked seeing it I didn't even think about shooting it. It was on his way out before I saw him for a split second, I pretty sure I would have missed him even if I would have been ready. LOL
How's that fawn call work for you?
If you move down south of Portland it's a lot better. IMO
