Cat media room vs dog ownership discussion room

r/cats’ public description covers pictures, videos, questions and articles about cats. r/dogs describes a room for dog owners of all experience levels to discuss responsible dog ownership.

In our directory, cats is much larger (about 9.5M, rank #82) than dogs (about 2.9M, rank #377). Activity samples diverge sharply: cats posts far more often (~608 posts/day vs ~73). cats’ sample is image-, gallery- and video-heavy with flairs such as cat picture OC, advice and medical questions; dogs’ sample is essentially all text with flairs such as misc help, behavior problems, health and training foundations.

Rule titles underline the split: cats bans spam/memes/ads and NSFW/abuse and limits name-my-cat posts; dogs requires good-faith posts, LIMA training advice and bans dangerous or ESA/service-dog fraud talk. SubMouse already compares dogs with Dogtraining; this pair is specifically cat media versus dog ownership discussion.

Choose r/cats for cat pictures, videos and light questions under its OC and anti-spam rules.
