Quick questions
What is the best mythological name for a black cat?
Nyx. She is the Night itself, and Homer says even Zeus feared angering her. A black cat named after the one being Zeus feared: accurate.
What was the name of Hades' dog?
Cerberus: three heads, one job. Every soul gets in, none get out, and his record was perfect until Heracles. More of his colleagues in our Greek monsters ranking.
What is the most loyal dog in mythology?
Argos. He waited 20 years for Odysseus, was the only one to recognize him under the beggar's disguise, wagged his tail once, and died happy. Ten lines of Homer that have outlived empires.
Whichever you pick, your pet's name now carries a whole saga. MythologyNow narrates those sagas like films: start at the gate with Cerberus, or ride with Freya and her cat-drawn chariot. Headphones on.
