Billy's post about the guitar-playing dog reminded me of my friend Mat Kamler, creator of Litterbox, the world's greatest cat heavy metal band.  Mat's site, EyeEnvision, is a flash cartoon animation site featuring original webtoons by Mat.  Mat photographed 3 of his 5 cats and recorded their meowing and set them to music.  The first time I ever saw a Litterbox video, I nearly busted a gut, and my cat (at the time) started hissing in time.  Here's a link to my personal favorite, Four on the Floor.  Mat has seven Litterbox videos on his site, as well as other funny flash animations.  Really a talented (and nice) guy.  Definitely worth a look and a laugh, and a donation to Mat.  Here's a link to Mat's MySpace site as well.  More Litterbox Videos Please!  Rock on, Mat!
