I never had decent luck with catnip at sets guarded with footholds, but could be how I used it with what Type of sets I used it at. Seemed like at Dirtholes when I used any catnip-based lure in or near the hole, the whole point was to get kitty to puts its foot on the pan of my trap. With catnip, there was a lot of movement (based on tracks left at the set) everywhere but the pan. When I switched to straight bait and a gland-type lure I nailed cats much more consistently.
So, I tried catnip lure on a sort of modified post-type set, where the point wasn't so much to have the pan/trap placement in proportion to kitty's nose/mouth and its front feet but moreso to where the cat would naturally step to work the set. I used "higher" type post to get the cat to stretch up a bit to rub its cheek against the lured spot on the post, and then just guessed about where I thought a foot would get placed when the cat worked the set this way.
After a lot of experimentation, walk-bys, empty trap checks, looking at tracks in the dirt pattern, etc. I switched back to big dirtholes loaded up with fish, red fox gland lure, and some cat glands...and I started picking up cats again.
Any other suggestions on catnip, where to use it and what sets it works with? I gave up on it but I'm always open to try things out...to some extent anyway.
