Mike--- Pull your cage and hose (clean) all the lure and paste out of it. Then get a spray bottle and mix a 75% water and 25% baking soda and spray the entire trap down (de-scent it) and let the trap dry. Use a clean pair of gloves to handle your trap---smoking your gloves puts tannin on them and tannin stinks to an animal.
When you set your cage, smooth the ground under it so it sits firmly and dose not move or shake. Before final placement of the trap, dig a small hole in the ground below where the pan will be and that is your lure location. Stick one end of a Q-tip into the lure and set the Q-tip in the hole below the pan.
Bait---Now, get or build a 15X15X16L cage w/lid and attach it to the back of your cage trap. Put your live poultry (we'll say chicken, banty chickens work well cause they scare easily) into the attached cage with feed and water. If the [beeep] cat wants to come in to eat poultry---feed him poultry. Besides, he's done it before and got away with it, so he'll try it again.
Make your cubby set with brush and cover the floor, making sure nothing interferes with the door operation---Loose the tarp. A few feathers scattered in front of the trap, as J.W. said, and hang some type of attractor---bird wing, surveyor tape,ect. 4-5' off the ground and within 5-15' of your cage trap.
Hope this info helps you out. I'm not a trapping instructor but I've been trapp'in cats for 40 years.
