First of all I think you should take the "attack cat" to the vet just to see if he's in some kind of pain. If he's healthy I think you should try Feliway.
Have you tried Feliway? It's a spray that contains feromones and it's supposed to calm the cats preventing them from spraying and show any aggressive behavior.
If you search the web you'll find quite som information about Feliway. I think you should give it a try.
