Animal-carrying cases have never been very comfortable. Spartan is closer to the truth. They're hardly elegant, either. More of a fashion liability than a fashion statement. But the new Classic carriers--with padded interiors and cross-ventilating airholes, leather handles and patterned or solid canvas-like vinyl--should satisfy both the pet and its toting master. For cats and for small and medium-size dogs. At Woody's Pet Center in Glendale, Santa Monica, Arcadia; Orange Company Pet Center in Orange. From $60 to $80.
