Anyone feeding my tabby cat?- Ridge Road N8 area

Hello, Over the past year my cat George (microchipped under the name Rocket which never stuck) has been going missing for a few days and coming home again for a couple of days, but recently has taken longer breaks from home and I havent seen him for 2 weeks. I am sure he is being fed elsewhere rather than got lost as when he did come home he looked very well. He is 14, tabby, and I've had him since he was a kitten. He is super friendly. Pics attached. I would ultimately like him to come home but would at least like to know where he is etc. We just lost his brother to cancer and if someone else has George then I want to know that if he is happy there they will at least look after him!
