I know one can purchase diapers for dogs,so sure if you look you will find similar for cats.Other then this perhaps a tiny babies disposable may do the trick,toweling babies nickers?
Good luck with it!
Have you tried beating it? LOL just kidding.
Have you tried getting the cat knocked up? That can be a temporary solution to your problem. hehehe
What about ear plugs?
Spaying is the only permanent solution.
