Cat and dog enthusiasts have debated for years about which animal is smarter, dogs or cats. Research has shown that dogs have about 530 million neurons compared to 250 million in cats.
“I believe the absolute number of neurons an animal has, especially in the cerebral cortex, determines the richness of their internal mental state and their ability to predict what is about to happen in their environment based on past experience,” neuroscientist Suzana Herculano-Houzel from Vanderbilt University says.
Of course, how smart can dogs be when they obey humans while cats get humans to do their bidding for them? Sometimes the smarter creature may be the one that gets the most while doing the least amount of work to get it.
