Meaning & Story

Cassi is an English feminine name, a short form of Cassandra or Cassidy — Cassandra from Greek mythology, the prophetess who was cursed to never be believed; Cassidy from the Celtic meaning 'curly-haired.'

Cassi has a breezy, friendly energy that suits a social, outgoing pet perfectly. It's shorter and punchier than Cassandra, lighter than Cassidy — a name that hits the sweet spot of feeling personal and warm. The mythological Cassandra could see the future but was never believed, which gives the name a subtle depth; but as a pet name, Cassi sheds all the tragedy and keeps only the bright, vivacious sound. It suits a lively female pet who seems to always know something you don't.
