Click on the black buttons to change stuff. Click on the cat's eyes to change their style. Click on the background to change its color. The light grey button is for making 'it' lighter and the dark grey button is for making 'it' darker. Next to 'extra features' you can click on the grey button with the pencil to change the color. If you want, you can take a screenshot of the cat you created and make it your thumbnail!
Thanks to @crookshankskitty for making the awesome cat creator
