If you have owned a pet (or previously owned a pet) have you noticed anything that specifically makes them happy?
I have a Siamese Fighting Fish. He loves the decorations being switched in the tank and will briskly swim around. It's a similar reaction when bringing him food. He bolts towards the top of the tank and waits.
