Don't know if this would work for a cat but it got rid of a dog problem I was having. A neighbor's dog kept peeing on my right front truck tire. I could not catch him at it. I kept gun handy for a couple weeks and no luck. I decided to get him at his own game. I got an old tire and wheel out of the barn, wire brushed it real good and placed it front of the right front tire. I then hooked the electric fence charger to the old wheel and grounded it real good. I poured a 5-gal bucket of water in front of it turned it on and waited.
I did not see it happen but I know he got his parts charged good when he peeed on it. It scared him so that about 3' away he dumped a load.
I did not see that dog for months and the problem stopped for good! Oo.
