Big Cats of the Stars Picture

Trigon belongs to Kepler, Dwarf and Quantum
Dysnomia belongs to Eris
Hi'iaka belongs to Haumea

Trigon is a Manticore, Dysnomia is a Sphinx and Hi'iaka is a Panther. Why a Panther? They're cats of magnificent coats in Greek Mythology and usually associated with Dionysus. Haumea can also be "related" to Dionysus, so why not?
