The brain of the domesticated cat is about five centimetres (2.0 in) long and weighs 25–30 g (0.88–1.06 oz). [1] [2] If a typical cat is taken to be 60 cm (24 in) long with a weight of 3.3 kg (7.3 lb), then the brain would be at 0.91% [3] of its total body mass, compared to 2.33% [3] of total body mass in the average human.
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] In fact, cats have an estimated 45 to 200 million odor-sensitive cells in their noses, whereas humans only have 10 million odor-sensitive cells ...
Cats are highly territorial, and secretion of odors plays a major role in cat communication. The nose helps cats to identify territories, other cats and mates, to locate food, and has various other uses. [7] A cat's sense of smell is believed to be about fourteen times more sensitive than that of humans.
Cats have an acute sense of smell, due in part to their well-developed olfactory bulb and a large surface of olfactory mucosa, about 5.8 cm 2 (0.90 in 2) in area, which is about twice that of humans. [79] Cats and many other animals have a Jacobson's organ in their mouths that is used in the behavioral process of flehmening. It allows them to ...
The existence and nature of emotions in non-human animals are believed to be correlated with those of humans and to have evolved from the same mechanisms. Charles Darwin was one of the first scientists to write about the subject, and his observational (and sometimes anecdotal) approach has since developed into a more robust, hypothesis-driven ...
Sense organs are transducers that convert data from the outer physical world to the realm of the mind where people interpret the information, creating their perception of the world around them. [ 1 ] The receptive field is the area of the body or environment to which a receptor organ and receptor cells respond.
