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 a visual field of view of 200° compared with 180° in humans, but a binocular field (overlap in the images from each eye) narrower than that of humans. As with most predators, their eyes face forward, affording depth perception at the expense of field of view. Field of view is largely dependent upon the placement of the eyes, but may ...
Cats and humans evolutionarily diverged from a common ancestor (boreoeutherian ancestor) approximately 80 million years ago, accumulating only 10–12 chromosomal translocations. [71] The order of eight genes on the cats' Y chromosome closely resembles that in humans. [72] Genes on X chromosomes of cats and humans are arranged in a similar way ...
In some cases, the cat exhibits no symptoms of the disease. [225] The same disease can then become evident in a human. [226] The likelihood that a person will become diseased depends on the age and immune status of the person. Humans who have cats living in their home or in close association are more likely to become infected.
Cats sometimes "head-bump" humans or other cats with the front part of the head; this action is referred to as "bunting". [43] This communication might have an olfactory component as there are scent glands in this area of the body, and is possibly for seeking attention when the cat turns its head down or to the side.

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.
