Check out this video of some dude's cat Buddy digging Slayer's set from Big 4 Live. I'm thinking the bong is probably on the other side of the couch.

Here's the video description from YouTube:

This is my cat Buddy. I was watching Slayer perform from the Big 4 concert and caught this little guy chillin' and watching as well. What's funny is how he looks so into it. I guess he takes after his master. Enjoy!
