What's going on? Why the Dormouse so happy?

A dormouse feel the weather changes, that winter has ended. He climbed on Yarrow flower alone, as if to greet the arrival of spring, the eyes narrowed in a line, mouth fell open, grinned, still purring, pleasure all written on his face. This lovely picture is recorded by a 28-year-old Italian photographer Andrea Zampatti with the camera.He spent a few days to shoot and he believes that wait until this very funny photos, it is worth.
