One of the things that we love the most about cats is how some of them, one day, just decide that they have had enough of this whole "being a stray" thing. They decide that they are done, and just like that, they find themselves a human to adopt and spoil them for the rest of their lives. It really is that simple. The time doesn't matter, the place doesn't matter. Once a cat decides that it is done, the world - or rather, the CDS - will do the rest.
You can be driving someplace when a kitten will jump straight into your car and adopt you. You could be going on a pizza run when you get adopted by a cat. You could be having a 2AM picnic when a cat approaches you and simply leaves you with no choice but to take them into your home, spend a whole lot of money on them and keep them for the rest of their lives. Cats have that power over us, and it happens all the time.
