A group of guys who have a popular fishing channel go fishing and are distracted by a friendly and agreeable calico cat. They called her Maruo. Next time they went to the same fishing spot, they arrived bearing gifts.
Once they made sure she was a stray, one of the guys adopted her and named her Marimo. There are plenty more videos of Marimo afterward, adjusting to being a pampered house cat, linked at Metafilter.
