We don't know exactly how, but sometimes, cats just know that it's time to get off the streets. These kittens make that decision and follow through with it till the end. They decide that a human is worthy of their magical presence, and that's it, the human can do nothing but go with it. That's how it always goes. We've seen it before. We've seen a kitten decide that it's done with outdoor life and sit on the driveway of a home until she gets adopted. We've seen a hungry cat decide it's done with street life, show up on a porch, and promptly adopt the humans who live in that house. We've even seen a kitten come up to a porch door, wanting to get inside, and end up getting adopted by another cat.
It happens time and time again, and this time is no different. This kitten went as far as to block a man's car so that he would help it. Luckily for the kitten, the man indeed could not resist its kitten-like charms and could do nothing but take it in.
