Let the dog vs cat wars begin!
An international team of researchers analyzed the outer layers of the brains of a variety of carnivorous animals – including dogs and cats. Looks like dogs stand out among carnivores for having a remarkably dense cerebral cortex.
The team looked at eight different meat-eating animals including species of ferrets, mongeese, raccoons, cats, dogs, hyenas, lions, and brown bears.
Based on their results, dogs have closer to 530 million neurons, compared to the 250 million of cats. What’s more, dogs had the most neurons of any carnivore, even though they didn’t have the largest brains.
