Arrival Story: A house on the corner of the street had Gamzee as a strictly outside cat, so he would often wander around and I had seen him every once in a while. One night he came to my porch while I was sitting outside, so I went in and brought him some food which he ate and then left.
He started frequenting my house because he was always fed, so I left dishes of food and even a litterbox out for him and he'd usually be found on my porch, sleeping or defending his new territory from others. The girl who lived in the house he was from said he was called Charlie and didn't seem too sure on his sex, even though he was pretty clearly a neutered male.
Eventually, when it got colder, I brought him inside and he practically never left.
