We celebrate the birthday of Arthur, our cat, every year on April 16th, so Arthur is an Aries--""energetic, impulsive, enthusiastic, positive."" However, when we tried to explain this to Arthur, he refused to lift his chops from the large astronomy book where he had been slumbering since the night before. Martha, the Persian next door, whose birth is recorded in a gilded document, is a Virgo--""exact, methodical, discriminating, intelligent""-but Martha has been teetering on a small maple for two days, having been routed by an explosive entrance of a newspaper through the front door, so there's no point in shouting up to her! However, having browsed through sections dealing with ""Lebensraum"" concepts, social and personal relationships, etc., we're convinced there's a constellation burning bright for every cat-somewhere. Have a cat nip or two--and enjoy.
