This is Katie...
Katie, just like you, learns about the world around her using her senses:
She sees the things around her with her eyes
She hears the things around her using her ears
She smells the things around her using her nose
Katie tastes using her tongue
She feels using her skin
Katie knows that her pets have the same senses as her and that they use the same body parts as her to see, hear, smell, taste and feel.
