We're calling it here on the 8th day of January in the year of our Lord 2014, the battle is over.  The battle for the cutest video ever posted on the internet has been decided.

The problem with finding the cutest video EVER is that people have different definitions of "cute".  Cat people love kitten videos.  Dog people love puppy videos.  Now both can be equally pleased with this video of cats and dogs meeting for the first time.  Enjoy.
