Which are smarter: cats or dogs?

There’s really not much in it. The ratio of brain to body size is slightly higher for dogs than cats, which may be because dogs are a social species and have evolved some extra brain to handle more complex communication and interaction. But cats have almost twice as many neurons in their cerebral cortex, the area involved in memory, attention and perception. Cats are harder to train, and won’t fetch things or guard their owner. But does that mean dogs are smarter, or cats are?
