Science says dogs are smarter than cats

"I believe that the absolute number of neurons possessed by the animal, especially in the cortex, determines the richness of their inner mental state and their ability to predict a situation based on past experience,"says Hermano-Hotel".

Dogs, it turns out, have about twice the number of neurons in their cerebral cortexes than what cats have, which suggests they could be about twice as intelligent.

The researchers also determined that brain size does not correlate with intelligence or number of cortical neurons.

The paper, which will be published in the journal Frontiers in Neuroanatomy (and nearly certainly maligned on Reddit, the Internet's haven for cat lovers), notes that the physical size of the brain doesn't necessarily relate to overall intelligence.

Scientists at Vanderbilt University have solved the age-old question: Which animal is smarter, cats or dogs?

That is not to say your cat isn't smart, and a lot of different factors go into this, but at the end of the day, the animal waiting at the door for you with the wagging tail has nearly three hundred million more critical neurons than a cat, and you can not argue science. Humans, by comparison, have around 16 billion.

The findings showed that while dogs have about 530 million cortical neurons, cats have 250 million. Herculano-Houzel did clarify that she is "100% a dog person".

Based on the number of neurons found, they speculated that dogs have roughly the same intelligence as raccoons and lions, while domestic cats have comparable intelligence to bears.

Carnivorous animals were compared in the study, consisting of 280 species of mammals characterized by teeth and claws allowing them to eat animals. "You can have animals with similar-sized brains, and they have completely different numbers of neurons". "And this implies that dogs have more cognitive capabilities than cats". Herculano-Houzel herself admits that, while the study was objective, she herself does have a bit of a bias.
