Welcome to Cathulhu, the Call of Cthulhu alternative setting where feline sleuths investigate the horrors of the Cthulhu Mythos.

In Cathulhu, discover the secret life of the cat as a Dreamlands warrior and a Waking World sleuth. Cats are the secret allies of humanity in the fight against cosmic horror; confronting overlooked machinations orchestrated from the sewers, tracking down sorcerers and cultists in the Waking World, and taking the fight to Nyarlathotep’s minions in the Dreamlands with the Cat Armies.

Cathulhu contains full character generation information for creating feline characters, feline abilities, background information on the cult of Bast, a short bestiary of feline opponents and an introductory adventure, ‘The Black Cat’.

Cathulhu is fully compatible with Call of Cthulhu sixth edition rules.
