It's an easy matching game with a silly concept that's easy to learn and explain. No more difficult than Uno, so can be played with children.
For gamers, it's a good warm up game for game night, since it's light and plays through quickly. I'd also use this as a holiday time killer, since it's simple enough to explain to non-gamers.
Bought it the first time as a gift for a cat-loving friend because of the cute art. After playing, bought a copy for myself.
