Seems to me you have been offered some fine solutions, all involving no electricity. Would not want you or anyone else to have a electrical accident.
Something tells me it would work just fine to set the trap in a cardboard box with a end cut out for a entrance and have the box in a trash bag with a little bait at the back of the trap. A little gas on the rag or the exhaust trick and you should have your solution.
If you do end up with a stink keep the location to a minimum. In the event you do end up with a stink baking soda and peroxide are your friend. Had a German shorthair that would tangle with skunks a couple times a year. Truly amazing how quickly and fully effective a bath with a little palmolive dish detergent and most important baking soda and peroxide to completely neutralize the oder.
Good luck with the striped puddy cat issue
