You may not know, but there are invisible Kittens around you, and Kitten GO! is the app which you can watch the Kittens that you can’t see with your naked eyes. Meeting and collecting the invisible Kittens may change your life. You have to walk to find kittens, that will make you move and lose weight!! By the time you had collected all the kittens, you must be more slimmer and skinnier!! Try it ! How to find Kittens Many Kittens, not like some monsters, live in houses. You don't have to go outside to meet Kittens. To find Kittens, just walk! The more you walk, the more you can feel the sign of Kittens. (iPad is a little heavy to carry, so if you find the button to call Kittens, touch it! Kittens will come near you.) Kittens don't like cars and bicycles. You won't be able to find Kittens on vehicles. If you need a little exercise, you can do it finding Kittens! There is a pedometer attached to the app, so you can see how many steps, distance you walked, how many floors you went up and down during the play. (Notice; Pedometer doesn't work on some devices such as iPads.) How to get the Kittens While walking, you may find gold, silver and bronze balls. Touch to pick them up. By tapping the balls at the bottom of the view, you can throw the balls to Kittens. Kittens move very fast. You can get Kittens by 100% probability with the gold balls, but gold balls are very precious. Don't waste them. Probability of silver and bronze balls are lower. Rank of Kittens There are 6 Ranks for the Kittens. Legend Rank S Rank A Rank B Rank C Rank D You can watch the Kittens on the Album. About the Stage On the left top of the view, you can find your current stage. When you go to a new stage, the Kittens that appear will change. You will be able to encounter more rare Kittens if you go to a higher stage.
