Kittenwar, based on the website, is played like the traditional card game "War" (there are several different variations of the game in the instructions). Each card has a picture, name, "rank: and overall score of an adorable kitten. The overall score is broken down into categories (the categories are not used in the basic game, but are in some of the variations). For the basic game the player with the kitten with the highest overall score wins the cards that round. My kids, who adore cats, love to play this game. It is good for my kindergartener as she has to figure out which number is higher. Sometimes we do get carried away gushing over the kitties. Highly recommended!
