Missing Ginger Male Cat in Dutton Street

He is male, ginger with striking dark markings. Yellow eyes. No collar. Last seen on Dutton St in Greenwich SE10 on Monday 28th at about 6pm. He is very friendly but does not wander far and always comes home. He has never been away for this long. I think he may have gone into someone’s house or shed and got stuck. Or gone a bit too far and is unable to find his way back to the house. We are extremely worried as he is still quite young. He will be very hungry and frightened. Please could you search your houses and outbuildings/gardens? And be aware in case your neighbours might have a cat in their house that does not usually live there. Thank you so much..he is really adored and has a sister who is also missing him terribly. He is microchipped
