No animals are actually harmed in the game itself, which models itself after Russian Roulette. Here's how the game's makers describe it "Players take turns drawing cards until someone draws an exploding kitten and loses the game. The deck is made up of cards that let you avoid exploding by peeking at cards before you draw, forcing your opponent to draw multiple cards, or shuffling the deck. The game gets more and more intense with each card you draw, because fewer cards left in the deck means a greater chance of drawing the kitten and exploding in a fiery ball of feline hyperbole."Sounds messy. And fun. Is it too late to get a NSFW deck for Christmas?
