My old cat Courtney used to let 2 black and white toms in the garden but no others. She also had a vendetta going on with Teabag, another female cat 5 doors down. They used to sit on their respective doorsteps and glare at each other. You could almost hear the theme from The Good The Bad And The Ugly playing.
Sadly the submissive one ran away to get away from the dominant one. We put missing posters up and got her back for a week but she ran away again. Apparently there was a pack of feral cats living in some nearby woods, so I like to think she had a reasonable life in the wild with them or got taken in by a nice old lady
