Named after a seventeenth-century philosopher with a dim view of human nature, Hobbes has the patient dignity and common sense of most animals I’ve met. Hobbes was very much inspired by one of our cats, a gray tabby named Sprite. Sprite not only provided the long body and facial characteristics for Hobbes, she also was the model for his personality. She was good-natured, intelligent, friendly, and enthusiastic in a sneaking-up-and-pouncing sort of way. Sprite suggested the idea of Hobbes greeting Calvin at the door in midair at high velocity.

With most cartoon animals, the humor comes from their humanlike behavior. Hobbes stands upright and talks of course, but I try to preserve his feline side, both in his physical demeanor and his attitude. His reserve and tact seem very catlike to me, along with his barely contained pride in not being human. Like Calvin, I often prefer the company of animals to people, and Hobbes is my idea of an ideal friend. The so-called “gimmick” of my strip—the two versions of Hobbes—is sometimes misunderstood. I don’t think of Hobbes as a doll that miraculously comes to life when Calvin’s around. Neither do I think of Hobbes as the product of Calvin’s imagination. Calvin sees Hobbes one way, and everyone else sees Hobbes another way. I show two versions of reality, and each makes complete sense to the participant who sees it. I think that’s how life works. None of us sees the world exactly the same way, and I just draw that literally in the strip. Hobbes is more about the subjective nature of reality than about dolls coming to life.
