Is breakfast being served yet??

This handsome fellow - we think he is a boy - started visiting us a couple of weeks before we lost Taz. Since then he has become a regular, in through the cat flap or the open patio door. He comes for some cat biscuits and a scratch at the cat scratching post, trying to avoid Mia who just tolerates him, though sometimes vocalizes her disapproval.
He doesn’t appear to be a stray. He’s well groomed and has a collar. And he is very beautiful.
Maple update: Back to the vets later today because although we are happy with his posture, movement and appetite., he appears to be over salivating and overgrooming, causing his chest and neck area to be sore.
