The domestic cat is attributed a value of between 1 and 1.71 (for comparison: human values range between 7.44 and 7.8). [1] [3] The largest brains in the family Felidae are those of the tigers in Java and Bali. [5] It is debated whether there exists a causal relationship between brain size and intelligence in vertebrates. Most experiments ...
The human brain contains 86 billion neurons, with 16 billion neurons in the cerebral cortex. [ 2 ] [ 1 ] Neuron counts constitute an important source of insight on the topic of neuroscience and intelligence : the question of how the evolution of a set of components and parameters (~10 11 neurons, ~10 14 synapses) of a complex system leads to ...
The size of the brain is a frequent topic of study within the fields of anatomy, biological anthropology, animal science and evolution.Measuring brain size and cranial capacity is relevant both to humans and other animals, and can be done by weight or volume via MRI scans, by skull volume, or by neuroimaging intelligence testing.
Felis is a genus of small and medium-sized cat species native to most of Africa and south of 60° latitude in Europe and Asia to Indochina. The genus includes the domestic cat .

The subfamily Felinae includes 12 genera and 34 species, such as the bobcat, caracal, cheetah, cougar, ocelot, and common domestic cat. [ 5 ] Traditionally, five subfamilies have been distinguished within the Felidae based on phenotypical features: the Felinae, the Pantherinae, the Acinonychinae (cheetahs), the extinct Machairodontinae , and ...
A domestic cat's sense of smell is 9-16 times as strong as humans'. [17] Cats have a larger olfactory epithelium than humans (about 20 cm 2), meaning that cats have a more acute sense of smell. [18]
