Happy days are here again in Mordecai Siegal's latest maneuver. Not that anyone needs all four--the information's too similar--but Siegal shuffles and deals out winning arrangements every time. This new book examines both dogs and cats in various patterns of peevish behavior, all of which are comprehensible and avoidable once several elementary principles are understood (especially life-in-the-wild analogues). And when Siegal unleashes his imagination to demonstrate how a tubby cat named Sara Lee developed poor eating habits or an Irish wolfhound named Jughead grew unmanageable, he comes up with case histories dramatic enough to film. Some of this is slightly recycled or can be found in less entertaining form elsewhere, but it's friskier than most and sensible besides.
