Even with dogs, using a shock collar for aggression issues is EXTREMELY risky, the risk being that if the timing is off at all, by even a fraction of a second, the animal will not associate their behavior with the shock, and will instead believe that the object of their aggression is causing the shock, causing them to aggress more. . .etc. I would not recommend a shock collar in this situation at all.
I have a cat who lives alone in the bedroom because she hates all the other cats and all people (she tolerates me but barely). She seems happy and unstressed. I think confinement could be a valid option.
