Cat Calls has been updated to add some cool effects which are only available through the iPhone/iPod Touch 3.0 update. With this update the cute kitties remain the same, but when you shake the device, the cute kitty sound shuffles. Will we purr at you, or will we be that evil scary cat? Only your device knows for sure! Shake even more to get multiple cats going at the same time! This update is sure to amuse you and your friends!
