I have two cats, and both of them are regular, 'alley' cats. I got my first cat, a tuxedo cat I named Nell, from a person whose (strictly outdoors) cat had kittens that were unwanted. She was the last to be adopted, probably because she wasn't pure black like her siblings (I've noticed that some people consider multicolored cats to be ugly). After about a year, I thought about getting her a playmate, but I didn't think I had the right conditions. 4-5 months later, I found a kitten on a street. I felt really sorry for him, and I was considering taking him, until I noticed his back leg was standing a bit unnaturally. At that moment I knew I had to take him in, otherwise he probably won't survive. So, a few vet visits later (it's was some kind of a vitamin deficiency) I had a healthy new kitten, Heathcliff. I love some animal breeds, but I could never buy a pet when there are so many left to die on the streets.
