One of the most amazing things about stray cats is that… out of nowhere, one day, they might decide that they don't feel like being stray cats anymore. That's how it has been all throughout history. Technically, we didn't domesticate cats. Cats domesticated themselves, and we are just he happy recipients of this process. And it's still happening. All the time, cats adopt humans. All the time, they decide that they don't feel like facing the harsh realities of the world - of hunting for their food and looking for shelter.
And that is exactly what the cat in this story did. One day, it woke up and decided that it was done with outdoor life, that it is time to be spoiled and love and to cuddle up in warm blankets every single morning. So, this cat chose a human to adopt, waited for the right opportunity, and just as the door to his chosen human's truck opened, she hopped inside, and she has been living happily ever after ever since.
