Animal lovers forever debate whether dogs are smarter than cats or the other way around. A group of researchers led by Suzana Herculano-Houzel, an associate professor of psychology and biological sciences at Vanderbilt University, examined the neuronal density and brain sizes of various animals and in their research, published in the journal Frontiers of Neuroanatomy, they concluded that dogs may be brainier than cats.

Dogs have cerebral cortexes with twice as many neurons — the brain cells responsible for thought, planning and behavior – compared to cats. Scientists have associated neuron density with overall cognitive ability – i.e. intelligence.

Then again, having brain cells is a lot different from actually using brain cells, as any glimpse into politics can tell you. So while dogs may have more brain cells than cats, cat lovers can rest assured that cats are more devious in using their brain cells to focus on what they want, which is total world domination at the expense of the human race.
