My current cat also insists on going out, and seems to have his own territory, but he does not actually hold court as your apparently does...Impressive!
And yes, cats do talk, and some are very talkative. (Siamese are very well known for this trait) we actually play by my responding back to him, and he comes to find me. The little guy also editorializes a great deal... he will be laying on the foot of our bed while my hubby and I converse, and out of nowhere comes this Huge sigh- I guess we're dull...
Interesting that you were curious enough to set up a camera... He sounds like he must be quite a character- Enjoy him!
Side note! My dad used to have an outdoor cat who "ruled" over a couple of farm dogs in the same fashion- and nobody or nothing dared to threaten that cat in any way... or the dogs got vicious! go figure!
