Gyrinx

Gyrinx, also known as Grynix, are strange, feline-like xenos creatures utilised as familiars to enhance the psychic abilities of both Aeldari and Human psykers. A Gyrinx resembles a large Terran domestic cat, with very thick and fluffy ginger or orange fur and bright blue eyes. They can grow up to a metre in length. Gyrinx are not truly sentient as such, but they have an astounding ability to empathise with other creatures, forming a mental bond with their owner which is comparable to true friendship. This mental empathy is of great benefit to the creature’s owner, whose own speed of thought and action are actually improved while the Gyrinx is in close proximity.
