Green Cat is listening closely

This is the second animal I did for the art book. I guess the editor will choose between Jacob the Polar Bear and Jacob the green cat.

Jacob the green cat has excellent listening skills. He can hear things that you and I can't. One day he heard me wondering. Another day, he heard me being indecisive. And he even heard me when I was drawing the shadow under his tail. I wonder if hearing all those things makes it hard for him to sleep.
