Lane Smith's Cat
You have gotsta see this.
Now, due to the unfortunate nature of the blog, I can't actually link directly to Mr. Smith's cat. Fortunately, he doesn't update all that regularly. So go to his blog, scroll down past the other cat images, and observe Noodle standing on the rock. That is not a pet cat. That is a pet mountain lion with a squishy squashy face. I'm still staring.
