Last year I trapped and dispatched 6. This summer I am up to 7 and know of three more in the area. They like the black sunflower seed that falls from our 5 bird feeders. They show up most every evening to eat them.
Last year I used cat food as bait and caught and released a few of our outside cats until they understood. It was all raccoon after that learning process.
I switched to black sunflower seed for bait this year. Seems to work better than cat food and no cats in the trap so far.
