Woo! Got my contributor's copy today and I can confidently assert that Sora is Mr. April in the I Can Has Cheezburger? 2013 Wall Calendar: A LOLcat Kalendar. He has to share that designation with three other cats* but I feel his natural star quality will shine through, provided he is not hiding as far under the bed as possible.
* Perhaps he is Mr. April 14-20? Week picked as it's our anniversary. :D
