Meet Agnes, an ordinary gray tabby with an extraordinary talent for mischief and adventure. A scrawny kitten rescued from a funeral home, she joins the Rasmussen family and becomes a confident, clever, and almost magical cat. Agnes disappears into hidng places from which she can't be found; she finds ways to join her people on adventures; she manages to satisfy unusual food tastes. Although never a mean cat, she lets the Rasmussens know when her desires are thwarted, but rewards them with purrs when she is happy.
