Sixtystone Press releases Cathulhu for Call of Cthulhu 7th Edition

Posted by Michael O'Brien on 19th Nov 2023

From our friends Sixtystone Press comes Cathulhu – the licensed Call of Cthulhu alternative setting where feline sleuths investigate the horrors of the Cthulhu Mythos! 

Cathulhu is fully updated to Call of Cthulhu 7th Edition, and available in premium colour softcover and PDF at DriveThruRPG. 

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 the English-language version of Katzulhu, which first appeared in the German-language Cthuloide Welten magazine, #1 and #2, in 2001/2002. The Katzulhu rules were reprinted in 2009 to accompany the release of Pegasus spiele’s Dreamlands sourcebook. 

Cathulhu was developed by Ingo Ahrens, Adam Crossingham and Daniel Harms from Ingo’s original Katzulhu, and was published in Worlds of Cthulhu magazine #4 in 2006. This edition is revised from the Worlds of Cthulhu version and includes additional information about Sabbat cats, and the cult of Bast through the ages.

Cathulhu was revised and updated in 2023 to be seventh edition compatible. It is produced under license by Sixtystone Press.
