I am using a pen. This pen has black ink. I am drawing on a paper. The paper is white. I am drawing an ear. Ears are used to hear. Cats have really big ears so they can listen. Cats also have fur which keeps them warm. Cats can have patterns on their fur. Cats have really cool noses and they can smell a lot of things. That is an eye. Eyes are used to see. Cats have big eyes so they can see all of their surroundings. Usually cats eyes are green. This is a cat's belly. it's on the bottom of the cat. it has super soft fur. This is a cat's back. It is on top of the cat. This is a cat's tail. Tails are super fluffy, but not all tails are fluffy. This is a leg. Legs are used for walking or running.
