Maru, the cat, is fat, and he loves jumping head first into boxes. What results is extreme cuteness. I love love love Maru! If you've seen any of his videos on Youtube (intro video: http://www.youtube.com/watch?v=z_AbfPXTKms) and have fallen in love with him too, you'll love even more his blog http://sisinmaru.blog17.fc2.com/. I can't get enough of Maru pictures and captions.
