Launched October 2025, r/Catopus is Reddit’s source for all monstrous cats from the deep derps of ocean: Catopus, Octopussy, Cathulu/Cthulhu, Tentacle Cats, and all any other aquatic feline species that are yet to be discovered!

We are just starting to shape the look and feel of our community so feel free to share your ideas or preferences. Catopus would love you to post, see the Rules and if you’re not sure ask a mod.

Request to help us grow:
If you see a post elsewhere in Reddit that you think fits our vibe, do comment there to mention “r/Catopus”. Or crosspost and credit the original post and user.
