There was a cat that lived behind a job I had years ago. It was a mean little shit and wouldn’t let anyone near it without hissing and running off. I was a smoker back then and I guess me being out there smoking everyday and just not bothering the cat, It learned I wasn’t a threat. Eventually It came and chilled next to me on my breaks, then after a month of that finally let me pet it. The cat would still hiss at anyone else that tried to pet it but me, was pretty awesome.
