I have used this method very effectively. I don't have a problem knocking off a feral or stray cat that causes havoc in my yard, but I don't need Sheriff Joe knocking on my door. Cheap cans of wet cat food and traps worked like a charm for me. Every morning I put the traps in the back of my truck and drove the cats 19 miles to work, which was an industrial area in Tolleson. Let em go and never saw them again.
This.
Harbor Freight medium trap. $20 and works great. We had the exact same issue with a next door neighbor. I keep my bass boat covered tight as a drum in a covered area on the other side of my house. Cats would still figure out how to get under the boat cover and cause major issues. Called the county, the city of Phoenix, then the humane society. They wanted $91 a cat if I dropped them off at their place. They then suggested that I bring them in so they can spay/neuter them, then place them back in the same neighborhood. HF trap with wet cat food. Trap still works as well as it did on day one.
