you're doing something right if you're seeing them....
Are they just not coming into range or what ? you could always do the belly crawl to get closer....you might try being aggressive too, but i would think that would be better in the spring rather than in the fall....or better yet, be submissive, just cluck and purr, scratching of the leaves to mimic feeding.....i dont know what you have done , so i'm just guessing....
