My roommate of back in the day and a friend were the ones who found him and his sibling as stray kittens who approached our home when they were outside chilling - the neighborhood we lived in had a lot of stray cats and we were familiar with the majority of them. We believed someone had dumped them recently in the area since all other cats/kittens were tabbies and tuxedo types plus Artemis and his sibling were extremely friendly to people while the other neighborhood cats were wary.
Due to their gentle nature and odd fur coat, Artemis and his sibling were brought in and my roommate made a plea to keep at least one of them (her reasoning was we'd split vet and food bills for the kitten that would stay) and the other sibling would find a home with someone else. I was against keeping either cat because I had pet rabbits and she could barely take care of her own cat at that time. While we debated the so-called arrangement, we bathed both kittens and Artemis's sibling got his name first - Angelo. From there, my roommate and friend decided on another "A" name which led to Artemis - which connected as well with Sailor Moon even though that cat character had white fur lol.
Eventually Angelo found a home with a coworker at that time and Artemis stayed with us - with Artemis picking me as his human when he decided to hang out in my room and wanting my constant attention (and taking into account of myself paying for his food, essentials, and vet bills). He wouldn't leave me alone so I took ownership of him. Eleven years later, here we are. He's been with me through my ups and downs and I've done the best I can to make sure he's taken care of.
