Well I have 2 males for a long time now and found a little female in the back yard who has been spraying or looks like she is spraying but no smell I can detect and I have watched her back up to the wall right beside my bed where she has claimed as her's try the wiggle tail bit but nothing happens, after a few attempts at this she stops.
I guess it doesn't work as the other 2 keep coming on my bed also, sometimes I have 2 happy males sleeping away and then walks miss grouchy and all hell breaks loose. She hisses and growls and then the other cats will leave. It doesn't seem fair since she has just arrived 4 months ago as a stray, but has taken over the entire animal population here. We have a collie mix Lab who Matilda (miss grouchy) doesn't seem to care for either and tries to smack her once in a while, but with no claws she doesn't hurt the dog at all. It is quite known that she is now the boss over everybody who lives in the house. So she keeps trying to mark territory but the water works are not cooperating Thank God for small miracles or my house would really smell like cat pee.
