The contest is simple: Caption the picture above, in which Zeus the cat and Daisy the dog are clearly up to something.
One submission (one post, one caption) per person, so make it good — there’s no prize for being first, just best. Entries have to be in the thread attached to this post; if you leave them on Twitter, Facebook, etc, they won’t be considered. Winner gets an ARC of The Human Division, which I will sign and (if desired) personalize. Open to anyone anywhere on the planet. Contest runs to 11:59:59pm Eastern tonight, May 1, 2013. I’ll pick my favorite caption and announce it in the next couple of days and ship out the ARC next week.
Update: Contest now closed — I’ll look through the entries and announce a winner soon(ish)!
