Procatinator is a fairly simple site: It serves a visitor an repeating animated GIF of some sort of cat motion paired with an exquisitely chosen song sourced by YouTube.
For instance, this link (captured below) takes a cat petting a stuffed animal and pairs it with George Michael's "Careless Whisper." Genius.
On the site's Twitter account, the crew has indicated that its server is exploding. As a result, initial loading of images and music may be delayed. Trust us, it's worth the wait.
