Because of their small size, domesticated house cats pose little physical danger to adult humans. However, in the US cats inflict about 400,000 bites per year that result in emergency room visits, at least 10% of which are bites from cats that were unprovoked. [23] This number represents about one in ten of all animal bites. [23]
Cat senses are adaptations that allow cats to be highly efficient predators. Cats are good at detecting movement in low light, have an acute sense of hearing and smell, and their sense of touch is enhanced by long whiskers that protrude from their heads and bodies. These senses evolved to allow cats to hunt effectively at dawn and dusk.
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.
When a familiar human slow-blinks towards a cat, the cat tends to approach the human more frequently than if the human has a neutral expression that avoids eye contact. This behavior may share features with the "genuine" human smile that involves the corners of the eyes narrowing.
Researchers at Lund University in Sweden are now setting out to find out if a cat's voice is affected by its owner's. Do cats sound like their owners? New study to find if felines have humans' accents
Life in proximity to humans and other domestic animals has led to a symbiotic social adaptation in cats, and cats may express great affection toward humans or other animals. Ethologically, a cat's human keeper functions as a mother surrogate. [100] Adult cats live their lives in a type of extended kittenhood, a form of behavioral neoteny.
Add in 15 tunnels and 8-9 bridges and a hugely-entertaining cat wheel and what you get is a kind of amusement park for cats. “I liken it to living in an aquarium of cats,” says Cohen.
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.
