Click the green flag to get the looks of your warrior. If you don't like it, try again. You can click the "change" button on each defining feature to change it to what you want. When you finish, click "done" and you can use your computer's screenshot button to save your new kitty.
NOTE: Please complete each feature. For example, if under clan you type in "Thunder", your clan will be "Thunder", not "ThunderClan", unlike other creations. All of the art is made by FunWarriorCats, I did none of it. I did, however, simplify the project and make it so you could choose defining features. See the link to the original game down below.
