When Debbie Parkhurst choked on a piece of apple at her Maryland home, her dog jumped in, landing hard on her chest and forcing the piece of apple to pop out of her throat. Debbie Parkhurst's husband, Kevin, was at his job at a Wilmington, Del., chemical firm when she took a midday break from jewelry and bit into an apple. When the Keesling family of Indiana were about to be overcome by carbon monoxide(CO), their cat clawed  at wife Cathy's hair until she woke up and called for help. For their timely acts, Toby, a golden 2 1/2-year-old dog, and Winnie, a gray-eyed American shorthair, were named Dog and Cat of the Year by the American Society for the Prevention of Cruelty to Animals. Neither Parkhurst nor Keesling could explain their pets' timely heroics,though Parkhurst suggested it might have been guided by God intervention . "That's what our veterinarian  said,"she said. "He wasn't making a joke; he's very spiritual, and now I have to agree with him." But both pets were themselves rescued in baby, Toby as a 4-week-old baby thrown into a garbage bin to die, and Winnie as a week-old orphan hiding under a barn, so helpless that Keesling's husband, Eric, had to feed her milk. As the Keeslings recalled it, a gas-driven pump spread carbon monoxide through the house. By the time Winnie moved into rescue spot, the couple's 14-year-old son, Michael, was already unconscious.
