@orangie Thats definitely not the same cat. If it was your cat they would've came to you. They have your scent. I've had one of my cats recognize me from down the street, so they definitely will come to you.
@orangie Even if he was chipped you cant track them unless they go the pound or vet they can scan him for a chip. Usually they do that if he had a collar. Did he have one? Make sure to call every animal shelter in that side of town tomorrow morning.
