What better way to celebrate the release of Mountain Lion than with tiny “mountain lions”? With the recent release of OS X Mountain Lion, much of our time this week has been spent playing with all of the new features. Since you need to know how to use the latest features anyway, we thought we’d make it as adorable as possible for you. Thanks to the Animal Haven Shelter for loaning us kittens.

This goes back to July, but I missed it until Twitter user Tom Schmidt alerted me to it today. Absolutely adorable.
