Cassandra is the siamese Jellicle. She's very graceful and very secluded. She doesn't spend much time with any of the other Jellicles. It's possible she's mates with Alonzo, or maybe Munkastrap in some productions. She sometimes accompanies, Demeter, and Bombalurina in The Gumbie Cat, in replace of Jellylorum. And most of the time she is the cat Mistoffelees picks to accompany himin this magic act of bringing back Old Deuteronomy.

Cassandra is a brown cat with no leg warmers or arm warmers, she has a white patch down her front, and her hair and tail are in a braided fashion. She is one of the better dancing cats, and would probably be around the age of 22 human years.
