The crazy fights between Charlie and his cat were historic. He would complain the cat was clawing up the furniture, waking him up at 4am and leaving the occasional hairball on his work desk. The cat complained the gourmet cat food was in fact not only not gourmet, it could hardly be considered food. Also, the cat insisted a cat door be installed. I feel like a prisoner, the cat said. Charlie finally gave in and said he would indeed put in a cat door. To show his thanks, the cat went out to the front yard and trimmed Charlie’s prize tree.
