Bill Hall, friend and butler to cats, admits to mixed feelings about such strange little creatures. He compares serving a cat to having a human 2-year-old in your life-something lovable that commands your affection but trashes your house. A cat, like a child, will mangle your begonias and then crawl into your lap to share the warmth of its feelings - but only if it really wants to. Hall, a syndicated humor columnist, admits his popular cat stories are really about humans and the rational reasons we bring cats into our lives - for entertainment and for fuzzy filler in empty nests. Hanging out with cats also gives hope for humankind. After all, if we can bond so tightly with creatures from another species, then we could easily learn to harmonize with fellow human beings.
