Unhappy Animals

Why was the animal unhappy?

Why was the dog unhappy? He had a ruff week. Why was the cat unhappy? His life wasn't purrfect. Why was the turtle unhappy? His brother was a shellout. Why was the crustacean unhappy? His mother's been a real crab lately. Why was the crawdad unhappy? His family was really shellfish. Why was the whale unhappy? He had no porpoise in life.
