What makes an animal smart? What IS smart?

Our human brains have taken us all around the globe, and even into space... But we are not the only clever creatures on the planet. Some animals are so smart that we don't even know the extent of their intelligence. How do some animals play? How do they use tools? How do they solve problems? How do they communicate? How do their memories work? Do they feel emotions like we do?
