A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
r/cats is the broad pictures/videos/questions room for cats. Specialty humour and niche aesthetic rooms help when you already know the joke or format you want.
Unrelated aquarium and misc related hits are omitted.
Use cats for general cat content and questions. Pick StartledCats for jump-scare gifs, OneOrangeBraincell for derpy orange cats, IllegallySmolCats for tiny-kitten humour, and CatsWithDogs when both species share the frame.
