Cats have excellent hearing and can detect an extremely broad range of frequencies. They can hear higher-pitched sounds than either dogs or humans, detecting frequencies from 55 Hz to 79,000 Hz, a range of 10.5 octaves, while humans and dogs both have ranges of about 9 octaves.[80][81] Cats can hear ultrasound, which is important in hunting[82] because many species of rodents make ultrasonic calls.[83] However, they do not communicate using ultrasound like rodents do. Cats' hearing is also sensitive and among the best of any mammal,[80] being most acute in the range of 500 Hz to 32 kHz.[84] This sensitivity is further enhanced by the cat's large movable outer ears (their pinnae), which both amplify sounds and help detect the direction of a noise.[82]
The musical returned to the West End in 2014 for a planned 12-week limited run at the London Palladium. Beginning on 6 December, the revival starred Nicole Scherzinger as Grizabella, and featured the original creative team, with direction from Nunn, choreography by Lynne and design by Napier.[62] Lloyd Webber was also involved and rewrote "The Rum Tum Tugger" and "Growltiger's Last Stand" for the revival.[101] The run was later extended through April 2015 and an additional 100,000 tickets were released, with Kerry Ellis replacing Scherzinger as Grizabella.[68] The musical returned once again to the London Palladium for another limited run lasting from 23 October 2015 to 2 January 2016, starring Beverley Knight as Grizabella.[102]

Although wildcats are solitary, the social behavior of domestic cats is much more variable and ranges from widely dispersed individuals to feral cat colonies that gather around a food source, based on groups of co-operating females.[130][131] Within such groups, one cat is usually dominant over the others.[132] Each cat in a colony holds a distinct territory, with sexually active males having the largest territories, which are about 10 times larger than those of female cats and may overlap with several females' territories.[87] These territories are marked by urine spraying, by rubbing objects at head height with secretions from facial glands, and by defecation.[87] Between these territories are neutral areas where cats watch and greet one another without territorial conflicts. Outside these neutral areas, territory holders usually chase away stranger cats, at first by staring, hissing, and growling and, if that does not work, by short but noisy and violent attacks. Despite some cats cohabiting in colonies, they do not have a social survival strategy, or a pack mentality and always hunt alone.[133]
A film adaptation directed by Tom Hooper for Universal Pictures and Working Title Films is scheduled to premiere on 20 December 2019. The film will star Jennifer Hudson as Grizabella, Taylor Swift as Bombalurina, James Corden as Bustopher Jones, Judi Dench as Old Deuteronomy, Jason Derulo as Rum Tum Tugger, Idris Elba as Macavity, Ian McKellen as Gus, Rebel Wilson as Jennyanydots and Francesca Hayward as Victoria.[292]

For the first several weeks, kittens cannot urinate or defecate without being stimulated by their mother.[6] They also cannot regulate their body temperature for the first three weeks, so kittens born in temperatures less than 27 °C (81 °F) can die from hypothermia if their mother does not keep them warm.[7] The mother's milk is very important for the kittens' nutrition and proper growth. This milk transfers antibodies to the kittens, which helps protect them against infectious disease.[8] Newborn kittens are unable to produce concentrated urine, and so have a very high requirement for fluids.[9] Kittens open their eyes about seven to ten days after birth. At first, the retina is poorly developed and vision is poor. Kittens cannot see as well as adult cats until about ten weeks after birth.[10]

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, the human keeper of a cat may function as a sort of surrogate for the cat's mother,[136] and adult housecats live their lives in a kind of extended kittenhood,[137] a form of behavioral neoteny. The high-pitched sounds housecats make to solicit food may mimic the cries of a hungry human infant, making them particularly difficult for humans to ignore.[138]
Cats are similar in anatomy to the other felid species, with a strong flexible body, quick reflexes, sharp teeth and retractable claws adapted to killing small prey. They are predators who are most active at dawn and dusk (crepuscular). Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small animals. Compared to humans, they see better in the dark (they see in near total darkness) and have a better sense of smell, but poorer color vision. Cats, despite being solitary hunters, are a social species. Cat communication includes the use of vocalizations including meowing, purring, trilling, hissing, growling and grunting as well as cat-specific body language.[7] Cats also communicate by secreting and perceiving pheromones.[8]
