We don't usually post photos of pets for our Photo of the Day feature, but who could resist these four cute kittens? This is the internet after all, home of all things cat-obsessed. Kristen Finnegan, a regular contributor to our Flickr pool, uses the handle "Animals & Clouds" and this photo really lives up to the name.
