Egypt: Heh and Hauhet, Deities of infinity and Enternity
Hauhet, as a goddess personifying fire, was shown with the head of a cat.
Hauhet was the feminine to Heh's masculine, more of a representation of duality than an actual goddess, so she was even less of a deity than Heh, and more of an abstract.
In Egyptian mythology, Huh (also spelled Hu, Hah, or Heh) was the deification of eternity in the Ogdoad, his name itself meaning endlessness, and is not to be confused with the identically named Hu a god in the Ennead system.
As a concept, he was androgynous, his female form being known as Hauhet, which is simply the feminine form of his name.
Like the other concepts in the Ogdoad, his male form was often depicted as a frog, or a frog-headed human, and his female form as a snake or snake-headed human.
