Dogs Are Smarter Than Cats, Study Says


Did you think cats were more clever and smart than dogs? Think again. According to the findings of a new study, the researchers have stated that it is the canines who are brainier than the felines, according to a report.

The researchers of the study concluded that dogs have dogs have cerebral cortexes with twice as many neurons — the brain cells responsible for thought, planning and behavior — when compared to cats.

In previous studies, scientists have linked neuron density with overall cognitive ability, that is, intelligence of a being.

In order to reach the findings, the researchers – Suzana Herculano-Houzel, an associate professor of psychology and biological sciences at Vanderbilt University and her team – evaluated the neuronal density and brain sizes of various carnivorans, a class of mammals that includes many predators – along with some omnivores and and a few herbivores.

The study said that the carnivorans were of special interest as they generally outsmart their prey to survive, therefore, they potentially had a higher number of neurone than their prey, which means they probably had higher intelligence.

The researchers attempted to probe further and examined the brains of eight mammals: cats, dogs, bears, lions, hyenas, ferrets, mongoose and raccoons. After their evaluation, they found out that animals who had larger brains also tended to have more neurone than the smaller one.

The researchers noted that dogs’ cortical neurons outnumbering cats’ cortical neurone. The dogs’ neurone amounted to 530 million while the cats’ were counted to 250 million. However, the researchers also discovered that brown bears had nearly as many neurons as cats, despite being significantly bigger in size in comparison.

They also noted that racoons had far more number of neurons than their small size brain indicated.

The findings of the study were published in the journal Frontiers of Neuroanatomy.
