Dog owners say their pets are smartest because their pet is loyal, joyous and can be trained.
Cat owners say it’s their pet — for exactly the opposite reasons.
But it now appears, that when it comes to raw brain power, dogs are clearly ahead.
Their cerebral cortex is particularly dense.
What’s the surprise about dogs being dense, cats say?
It’s all about efficiency when it comes to hunting.
It seems dogs have about 530 million neurons calculating their behavior, as opposed to 250 million in cats.
Dogs had the most neurons of any carnivore — even though they didn’t have the biggest brains. Brown bears had roughly the same number as cats.
