Click any of the little circle Icons and they will take you somewhere where it tells you to fill something out. Press [space] to hide the boxes, 0 (zero) to hide the side views, and 1(one) or 2(two) to change the pose of the cat (left or right). Color the cat, including the left and right poses. When you remix please make the Title the name of your cat.
Thanks to @Shadetail for making the bio!
