One day in a quaint little pet store, a cat has gone nuts. It nearly killed all the pet mice in a time, no matter by tearing them apart into pieces or by bump they off the path. In the pet store, the crazy cat shows no mercy to the mice, leaving the little store a mess with the dead mice and blood all around behind. Mouse Mash is an action game, available on flash-games.net, for your spare time entertainment and relaxing. You can master the brutal bloodlust cat with LEFT and RIGHT ARROW KEYS, while jump with UP ARROW KEY. Have fun chasing the shivering mice!
