i've been meaning to link to this purrrrfect video for a long time...and here it is...(note: there's a commercial at the start that runs about 10 seconds)
[youtube]http://www.youtube.com/watch?v=jnk15Wf6xMU&feature=youtu.be[/youtube] (i hope i got the link right)
note: i don't know anything about Assassin's Creed, but the video is adorable. This guy also has a "behind the scenes" video which is tooooo cute as well.
ENJOY! It certainly perked me up the last few weeks!
