Need another great way to kill some time at work? Invade your favorite websites with animated cat .gifs courtesy of the folks at Meowbify.

Because no website is complete without some cats on it, Meowbify has provided a platform by which you can replace regular images with .gifs of attacking cats, cats falling in the bathtub, cats vs. dogs — all the classics! Run any website through Meowbify’s online portal, sit back, relax and enjoy all the furry cuteness you can handle.

This adorable technology was pioneered by developers at Mobify, whose normal shtick involves adapting websites for the mobile universe. Some sites work better with Meowbify than others, but part of the fun is finding out which of your oft-visited sites capitulates to Meowbify’s cavalcade of cats. on CNN
