At this rate, the other three cats will likely get sick too and by then, we may have to get rid of a couple (or all if it's that bad). I know we can't keep Rajah if he keeps this up. Mom and I are fed up with his shitting everywhere.
This is why if I ever buy a pet, it won't be cats or dogs. Probably a hamster, a guinea pig, or a rabbit. Or maybe fish.
