SCHNAUTZIE

The three-year-old feline saved her parents's lives when she smelled a lethal gas leak in their Great Falls, Mont., home, and woke up owner Trudy Guy by sitting on her chest and patting her nose. After hearing a hissing sound, Guy then woke her husband, Greg, who realized the scent and sound were coming from a burst pipe, and the trio immediately evacuated.
