Cthulu Cat by Pandania

An ordinary Japanese high school student takes home an abandoned supernatural cat left in a cardboard box. Maybe he shouldn't have meddled with kitties beyond human comprehension--after all, it had tentacles where its whiskers should have been! But it's too late!

With no Elder Sign on the cat door, soon the pick of the Mythos litter starts to invade his house, as furry and feline versions of Hastur, Yog-Sothoth, Nyarlathotep, and other adorable Lovecraftian horrors blast his mind, whisper impossible secrets, and generally get underfoot!

Cthulhu Cat is a one-shot, full-color gag manga collection that is a charming tribute both to Lovecraft's stories and Lovecraft the cat lover, translated by Zack Davisson (Kaibyo: The Supernatural Cats of Japan, H.P. Lovecraft's At the Mountains of Madness, H.P. Lovecraft's The Shadow Over Innsmouth)!
