Humans seem to be fascinated by animals who can do things that we cannot. For example, HowStuffWorks has answers to questions about camel humps, Hawk vision, night vision, fish gills and so on. And so it is with cats purring. We cannot purr, so we are interested in how cats can do it. It turns out that domestic cats, some wild cats like pumas and mountain lions (in general, any big cat that cannot roar) and even raccoons are all able to purr. Humans happen to smile and laugh when they are happy, and dogs wag their tails.
