Street cats have serious attitude. He probably just did a 'You've gotta ask yourself a question: "Do I feel lucky?" Well, do ya, punk? ' on the black and white - who recognized potential Trouble when he saw it and hasn't come back.
Terribly polite though which is why (although they're not entirely relaxed in each other's presence) you don't seem to have had any real trouble between him and Daisy?
He's absolutely fine - he's fascinating everyone on our street because he looks so different and doesn't stop talking! I've had to explain to several people that he's not complaining, he's just talking and no, he doesn't need food (he has food out all the time so eats when he's hungry) and he isn't locked out as he has a catflap
He follows us up to the corner of the road but so far has decided that's the limit of his territory - he and the aggressive black and white cat seem to have come to a detente as the other cat hasn't come into our garden for a few weeks now
He and Daisy are getting a little more relaxed in each other's presence but it's obviously going to be a long slow process
