So Big!

My caterpillar is very furry-looking, even though he technically does not have any fur. He has little spikes all over, and is a blue-grey color with white spots. As for his length, he is continually getting bigger and fatter and is about an inch and a half. He moves around a lot and his food supply is quickly diminishing. If he doesn't turn into a chrysalis soon then I will have to obtain more food from my professor.
