Who has a dog has no doubts: Fido "lacks only the word", for the rest they are humanoids, facts and finished. This is demonstrated by the fact that they are loyal, joyful and can be educated. For exactly the opposite reasons, whoever has a cat thinks the same way: Felix is ​​wild and independent, a predator with a free spirit - how to deny that it is a symptom of intelligence?

So, who is smarter between cats and dogs?

Apparently divided between Fido and Felix, researchers at the University of Salford (UK) decided that a final point was needed on the issue. Thus, they "translated" and cataloged many animal behaviors, studied and evaluated them and finally published the results of the study in the scientific journal Animal Cognition.

Stubborn four-legged. The first fact emerged is that one of the most frequent requests coming from domestic animals is not "give me pappa" (as many tend to believe, especially cats) but "let me cuddle".

With regard to intelligence, as a previous study revealed, if we consider only the "power" of the brain, dogs will win big. Their cerebral cortex is indeed very dense with neurons: about 530 million, against the 250 million of cats (so to speak: a human brain boasts about 16 billion cortical neurons). This, scholars say, gives dogs a huge advantage.

In fact, the number of neurons affects the perception that animals have of their surroundings and their ability to predict what will happen. Activities that dogs do better than cats, managing to re-elaborate past experiences more accurately and learn from them. This, together with other hereditary and genetic factors, the researchers say, also explains why dogs (and not cats) are skilled hunting animals.

Top carnivores. The dogs also, on the neuron front, win the comparison even with other carnivores, positioning themselves among the animals that have the most: brown bears, for example, big and big as they are, have roughly the same number of neurons as cats .

We love dogs from the Stone Age

All agree then? Truce between canine and cat lovers? Not at all: the study does not all agree. There is maretta among feline lovers, who raise another objection: and if other factors were considered in addition to the number of neurons to evaluate an animal's intelligence? At the next study the hard answer.
