Answer:
I'm the source of all emotion but I'm caged in a white prison.
When I am caught I am thrown away. When I escape you itch all day.
I am always hungry I must always be fed. The finger I lick will soon turn red.
My tail is long my coat is brown I like the country I like the town. I can live in a house or live in a shed And I come out to play when you are in bed.
I go in hard, come out soft. Blow me hard and I'll make a pop. What am I?
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
