In a world of humanoid animals Pussy Katnip was a hat-check girl, and sometimes torch singer at the Kit Kat Night Club.
However when she “smells trouble” or danger Pussy found some privacy and took a swig, either from the hip flask she often carried, or from a bottle hidden in her apartment or at the club, of a substance she had invented which she called “Fizz” or “Katnip Fizz” that for a short time boosted both her natural agility and strength to super levels, while at the same time raising her “trouble sense” to full blown clairvoyance, letting her tell when “mugs” much bigger than her were about to take a swing at her, as well as other psychic abilities.
Thus enhanced she kept her world both safe from evil-doers and entertained.
