Science shows dogs smarter than cats

Posted: Updated:

An age-old debate between dog lovers and their feline counterparts may have an answer, according to science.

New research from Vanderbilt University found dogs have "significantly more" neurons in their cerebral cortex than cats do. In nonscientific terms, dogs are smarter than cats.

Cortical neurons in the brain aka "little gray cells," are associated with thinking, planning and complex behavior. All of which, according to the university, are considered "hallmarks of intelligence."

Researchers found dogs have roughly 530 million cortical neurons while cats have around 250 million. If you're wondering, the human brains has 16 billion.

The study, first of its kind, according to the university, centered around counting the number of cortical neurons in the brains of several carnivores from ferrets and raccoons to cats, dogs, lions and brown bears. 

The results were published in a paper, that's title begins with the words, "Dogs have the most neurons, though not the largest brain."
