Research suggests dogs are brainier than cats

In the study, researchers compared different species of mammals to see how the number of neurons in their brains related to the size of their brains. So dogs have around 530 million neurons whereas cats have half of it which is around 250 million.

In the scientific work of the group of global experts, in addition to cats and dogs who participated lions, ferrets, raccoons and brown bears, however, most scholars interested in the intellectual opposition to Pets.

"We did not study their behavior, so we can not (and do not) make any claims about how intelligent they are", researcher Suzana Herculano-Houzel, an associate professor at Vanderbilt University, told HuffPost in an email.

Just because an animal is bigger and has a bigger brain size, that doesn't mean it has more neurons.

"At the least, we now have some biology that people can factor into their discussions about who's smarter, cats or dogs".

She said: "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". In terms of energy, the brain is the most expensive organ in the body and its requirements are proportional to the number of neurons.

The researchers also learned that the domesticated animals in the test group (dogs, cats, ferrets) have similar brain to body weight ratios as the wild animals in the group.

"If you consider that neurons are the basic information processing units of brains, then whoever has the most neurons should also have the most information processing capabilities", says Herculano-Houzel, whose team is publishing an article in the open access journal Frontiers in Neuroanatomy.

Celia Haddon, cat behaviourist and author of "100 Ways For A Cat To Train Its Human", said cats may have fewer neurons than dogs because they are not as social.

All that said, while this study suggests dogs might be more intelligent, research from 2014 indicates that when it comes to humans, cat lovers may be smarter than their dog-loving counterparts. "Diversity is enormous. Not every species is made the same way".
