11 Days of Hallow Crossing - Sidhe Cats

Welcome to the celebration of Hallow Crossing, Book 2 of The Fair Folk of Mullarkey Series. Today, I’ll be talking about another behind-the-scenes, cozy-fantasy inspiration.

Sidhe cats (pronounced “shee”) are not one specific creature in traditional myth, but rather a folkloric idea shaped from several overlapping traditions. The closest direct ancestor is the Cat Sìth of Scottish lore—a large, fae feline said to haunt the Highlands. Described as a black cat with a white spot on its chest, the Cat Sìth was believed to be no ordinary animal, but a fairy creature or even a witch in feline form. It could move silently between the human world and the fairy realm, appearing at traditional crossings (doorways, crossroads, and the edges of forests). 

Unlike domestic cats, Sidhe cats are rarely bound by human affection or loyalty. They may accept offerings—milk, cream, or a warm place by the hearth—but such gestures are less about companionship and more about respect. In older traditions, failing to honor a visiting fairy cat could have dire repercussion for your household, while kindness might earn some protection. Still, Sidhe cats are fickle and their favor is never guaranteed.

Sidhe cats are often depicted as observers rather than participants, witnesses to secrets both human and otherworldly. In storytelling, they serve as omens, guides, or even judges of character. A Sidhe cat that lingers may be taking your measure, while one that vanishes abruptly may be signaling a shift in fate. They are guardians of in-between spaces, drawn to moments and places where the veil between worlds thins. You might find one watching from a stone wall at twilight, perched atop a burial mound, or slipping through a half-open door just as a storm rolls in. 

Ultimately, Sidhe cats embody the essence of the fae themselves—beautiful, dangerous, and impossible to fully understand—an essence that is often mirrored in domestic cats, making one wonder if the Sidhe cats once intermingled with ordinary hearth cats.

In Hallow Crossing, Joelle has the dubious honor of hosting a Sidhe cat at the Cedar Grove Inn. I took inspiration for Shae from the Highland legends of Sìth cats. Like most cats, Shae keeps her own counsel as she walks the liminal spaces between our world and the fae realm. 

The artist, Anthony Smith perfectly captured Shae’s sassy look for a chapter header. He created three more seasonal sketches to introduce each season in Hallow Crossing. I hope you’ll check them out.
