Few things in life are better than videos and GIFs about cats -- they bring joy to people. If you feel that way, then you'll probably want to download this new iOS app called Cat Shake. As its name suggests, the application requires you to, well, shake your device to fulfill its purpose. Once you do so, your reward will be too-cute-to-handle cat videos, "classic" cat GIFs and, because why not, adorable cat sounds. For those of you who don't have an iPhone or iPad, don't worry -- you can always go to Tumblr TV, type in what cat you're in the mood for (we'd recommend "funny cat") and problem solved. Or, you know, there's YouTube too.
