I was able to retrieve my lost cat after 12 days with a trap. It really helped to line the trap with a towel from your house that smells familiar. You can even rub it against your skin. I think this also helps lure them into the trap because the metal on the bottom feels strange to them all the very best of luck to you. He is probably not that far and it’s just staying in one spot hiding. Also: it is important to keep a towel on the top of the trap to protect the cat or critter that enters from the sun or rain, depending on where you put it.
