I think I've had more older cats that were "feral" like the main one in the video. Usually they develop that distrust of humans over time. I remember one cat I had that would hiss at you if you came even close to him. Of course he was an outside cat, because there was literally no way to get near him, but he would sit on my porch every day, and I'd feed him, and occasionally, rarely, he'd even let me pet him. He kinda also looked like he had visited the pet cemetery 7 or 8 times before. But, having a hard life and distrusting humans doesn't mean you don't deserve to be fed.
