While I think that poster is being a dick, I’m gonna make the argument that cats are basically equal to dogs, if not a bit more work. Dogs can shit outside without being destructive to native wildlife, and cats shit in a box that you have to regularly keep clean. If you get a lower energy dog, they only need a walk once or twice a week and yard time. A short-haired dog doesn’t really need regular grooming besides nails, which you often have to do for cats as well if they scratch everything but their post.

Basically, I think it’s much of a muchness, and comes down way more to the individual creature and their personality.
