Do you have a friend who's always covered in cat hair and smells vaguely of Fresh Step? It doesn't matter if she's young or old; you can be a crazy cat lady at any age. There's a 90% chance that I myself am, or am on my way to becoming, this girl. As anyone who loves a cat will know, they're all kinds of lovely, but you don't even have to own one to be a cat lady at heart. Other symptoms include Google Images searches for "kittens snuggling" and loving the Samuel L. Jackson-narrated African Cats.
