Castor & Pollux Cat Name Pairs
Castor and Pollux — the Dioscuri in Greek, the Gemini in Latin — are the twin brothers of Helen of Troy, born to Leda after her encounter with Zeus disguised as a swan. The famous wrinkle in the story is that only one of them was immortal: Pollux was a son of Zeus, while Castor was a son of Leda's mortal husband Tyndareus, which made the two half-brothers raised as twins. When Castor died in a cattle raid, Pollux begged his father to share his immortality so they would not be separated. Zeus agreed in the form of a compromise: the brothers would alternate days — one in Olympus, one in the underworld — or, in another version, would be placed together in the sky as the Gemini constellation. The pair is a different shape from Apollo and Artemis or from Romeo and Juliet. Castor and Pollux are about loyalty across an asymmetry — one cat who acts like he was always going to be here, and one cat who acts like he had to negotiate his way in. The Castor cat is often the older or more grounded one: steady, food-motivated, willing to sleep through fireworks. The Pollux cat is the showy one, the climber, the cat who pulls faster reflexes out of the household. Names that work as a daily wink at the Gemini constellation overhead.
When choosing a castor & pollux pair, think about how the two names sound when called together. The best pairs share a similar rhythm and syllable count, so they roll off the tongue naturally. Try saying both names out loud in sequence — at the food bowl, during a cuddle, and when breaking up a 3am wrestling match — to make sure the combination feels right in every situation.

Frequently Asked Questions
Who were Castor and Pollux?
They were the twin brothers of Greek and Roman myth, sons of Leda and known collectively as the Dioscuri (Greek) or the Gemini (Latin). Pollux was a son of Zeus and immortal; Castor was a son of Leda's husband Tyndareus and mortal. After Castor died in a cattle raid, Pollux asked Zeus to let him share his immortality with his brother — one version has them alternating days between Olympus and the underworld, another places them together as the Gemini constellation, the bright stars Castor (Alpha Geminorum) and Pollux (Beta Geminorum).
Are Castor and Pollux really twin names if one is mortal and one is divine?
That asymmetry is the point. The Greeks called them twins because they were raised together and inseparable in temperament, not because they had the same father — this kind of half-sibling twinning is common in Greek myth. For two cats, the names work especially well when one cat clearly behaves like he has been here forever and the other like he is the new arrival who decided to make it permanent.
Will most people recognize Castor and Pollux as cat names?
The constellation Gemini is the most-recognized handle for the pair, so people who do not know the myth often catch the reference through astrology or astronomy. Pollux is also a real, currently-named star — the brightest in Gemini — which gives the cat-naming pair a nice extra hook. If you want to soften the obscurity, Cas and Pol work well as everyday calling names while keeping the full Castor and Pollux on the vet paperwork.
