I thought that ol' Spaw would have had one of them Little Golden Faucets installed on his cat(s) by now. Sheesh, they been around for years -- first for human vascetomees and when that didn't work they found they found they worked great to prevent cats peeing on the furniture, rugs, walls, ceilings, sub-basements and other things. Just turn 'em on when the cat has to go and then turn 'em back off. They have great washers, too, so you don't have to do a lot of maintenance on 'em.
Ask your vet about 'em. LGF -- the catstaffer's best friend.
Endorsed by Hillary Clinton, who had 'em installed on Bill.
