Glue sheet traps.. and a piece of dog food in the middle.. or like someone else said, gallon of regular unleaded and a road flare, claim it caught fire just sittin there and get a new one lol

 

If the live trap doesn't do it I'll go with the sticky trap. I definitely won't go the cat route. I tried that once in a '67 Chevelle once. The cat ripped the crapola out of the front seat and a door liner, but failed to get rid of Mickey and friends. I only had myself to blame.

Smart little sucker! Live trap then donate to a research center. They will definitely want to poke its little brain to find out how smart it is and how it does the Houdini.
(for research purposes, of course) .
