Remember that Medieval manuscript with the centuries-old pawprints? Today's proof that cats have always loved ruining things comes in the form of cat pee.

In 1420 a scribe in what is now the Netherlands discovered that a cat had urinated on a document he was working on. Instead of scrapping the work, he added an addendum to the piece, with some words of wisdom for future cat owners. While originally written in Latin, in English the text reads

Here is nothing missing, but a cat urinated on this during a certain night. Cursed be the pesty cat that urinated over this book during the night in Deventer and because of it many others [other cats] too. And beware well not to leave open books at night where cats can come.

Check out this 15th Century manuscript. Notice anything familiar? In totally-non-shocking-news-of-the-day, it turns out cats have been walking on whatever you're writing since the dawn of time. Emir O. Filipovic of the University of Sarajevo's History Department discovered the medieval kitty prints.

We can only assume that somewhere, beyond the reach of time, in a small ancient monastery in the mountains, the muffled sounds of "SNOWBALL, OFF. OFF. DOWN. GET DOWN, SNOWBALL. BAD KITTY. DAMNIT, SNOWBALL GO SOMEWHERE ELSE," carry across the medieval vales and valleys.

Cyoot puppehs and funneh goggies: I Has a Hotdog has 'em all!

More than 65 kittehs live underneath St. Petersburg's Hermitage Museum. Their mission? To protect the museum's precious artwork from rodents with an indiscriminate taste for all things chewable. They are, of course, fed and cared for by a dedicated staff, and other job perks include free admission to one of the world's most prestigious museums. The cats employed today are the latest in a line of feline workers that stretches back more than 200 years. Think of that the next time you look over at your lazy fluffball, asleep in a sunbeam.
