Purring may have developed as an evolutionary advantage as a signalling mechanism of reassurance between mother cats and nursing kittens. Post-nursing cats often purr as a sign of contentment: when being petted, becoming relaxed,[143][144] or eating. The mechanism by which cats purr is elusive. The cat has no unique anatomical feature that is clearly responsible for the sound.[145] It was until recent times,[when?] believed that only the cats of the Felis genus could purr. However, felids of the genus Panthera (tiger, lion, jaguar, and leopard) also produce non-continuous sounds, called chuffs, similar to purring, but only when exhaling.[146]
Cats started the megamusical phenomenon, establishing Broadway as a global industry and directing its focus to big-budget blockbusters, as well as family- and tourist-friendly shows. Its profound but polarizing influence also reshaped the aesthetic, technology, and marketing of the medium. The musical was adapted into a direct-to-video film in 1998, with a feature film adaptation by Tom Hooper set to follow in 2019.

Once your vet has cleared your kitten as free of disease and parasites, it’s safe to let your new kitten explore its new surroundings and other pet roommates. Handling and playing with your kitten at least once a day will help him form a strong emotional bond with you. If you have children, monitor their introduction to the new kitten to make sure it’s a positive experience for both the kitten and child.
Cats is based on T. S. Eliot's 1939 poetry book Old Possum's Book of Practical Cats, with the songs in the musical consisting of Eliot's verse set to music by Andrew Lloyd Webber.[1] The musical is unusual in terms of its construction; along with Eliot's poems, music and dance are the main focus of the show at the expense of a traditional narrative structure.[2] Musicologists William Everett and Paul Laird described Cats as "combining elements of the revue and concept musical".[3] The plot centres on a tribe of cats called the Jellicles, as they come together at the annual Jellicle Ball to decide which one of them will ascend to the Heaviside Layer (their version of heaven) and be reborn into a new life.[4] The bulk of the musical consists of the different contenders being introduced, either by themselves or by other cats.[5]
By 2012, the royalty payments from Cats to the Eliot estate had totaled an estimated $100 million.[294] Valerie Eliot used a portion of this money to establish the literary charity Old Possum's Practical Trust, and to set up the T. S. Eliot Prize which has since become "the most coveted award in poetry".[337][338] Cats also turned things around for the independent British publishing house Faber and Faber. As the publisher of Old Possum's Book of Practical Cats, royalties of up to £1 million annually[316] kept the then-struggling Faber afloat during the 1980s.[339] Moreover, the musical led to a surge in the sales of Eliot's book.[1] The success of Cats led Faber to turn another of their literary properties, Ted Hughes' The Iron Man, into a 1989 musical of the same name.[340]

Before Old Deuteronomy can announce his decision, Grizabella returns to the junkyard and he allows her to address the gathering. Her faded appearance and lonely disposition have little effect on her song ("Memory"). With acceptance and encouragement from Jemima and Victoria, her appeal succeeds and she is chosen to be the one to go to the Heaviside Layer and be reborn into a new Jellicle life ("Journey to the Heaviside Layer"). A tyre rises from the piles of junk, carrying Grizabella and Old Deuteronomy partway toward the sky; Grizabella then completes the journey on her own.[i] Finally, Old Deuteronomy gives his closing speech to the audience ("The Ad-dressing of Cats") and the show comes to a close.

As well as being kept as pets, cats are also used in the international fur[238] and leather industries for making coats, hats, blankets, and stuffed toys;[239] and shoes, gloves, and musical instruments respectively[240] (about 24 cats are needed to make a cat-fur coat).[241] This use has been outlawed in the United States, Australia, and the European Union.[242] Cat pelts have been used for superstitious purposes as part of the practise of witchcraft,[243] and are still made into blankets in Switzerland as folk remedies believed to help rheumatism.[244] In the Western intellectual tradition, the idea of cats as everyday objects have served to illustrate problems of quantum mechanics in the Schrödinger's cat thought experiment.
Cats hunt small prey, primarily birds and rodents,[155] and are often used as a form of pest control.[156][157] Domestic cats are a major predator of wildlife in the United States, killing an estimated 1.4 to 3.7 billion birds and 6.9 to 20.7 billion mammals annually.[158][159] The bulk of predation in the United States is done by 80 million feral and stray cats. Effective measures to reduce this population are elusive, meeting opposition from cat enthusiasts.[158][159] In the case of free-ranging pets, equipping cats with bells and not letting them out at night will reduce wildlife predation.[155]

A kitten is a juvenile cat. After being born, kittens are totally dependent on their mother for survival and they do not normally open their eyes until after seven to ten days. After about two weeks, kittens quickly develop and begin to explore the world outside the nest. After a further three to four weeks, they begin to eat solid food and grow adult teeth. Domestic kittens are highly social animals and usually enjoy human companionship.

Cats are known for spending considerable amounts of time licking their coats to keep them clean.[147] The cat's tongue has backwards-facing spines about 500 μm long, which are called papillae. These contain keratin which makes them rigid[148] so the papillae act like a hairbrush. Some cats, particularly longhaired cats, occasionally regurgitate hairballs of fur that have collected in their stomachs from grooming. These clumps of fur are usually sausage-shaped and about 2–3 cm (0.8–1.2 in) long. Hairballs can be prevented with remedies that ease elimination of the hair through the gut, as well as regular grooming of the coat with a comb or stiff brush.[147]
Nunn was also adamant that the orchestra for Cats be hidden backstage — out of the audience's view — so as not to break the immersion.[90] Adding to the experience, the show usually includes a lot of audience interaction, such as during the overture when the cast don flashing "green eyes" as they make their way through the audience in the darkened theatre.[80][91] In the original Broadway production, catwalks were built to connect the stage to the boxes and balcony so as to give the cast access to the entire auditorium during the show.[92]

The Dutch live entertainment company Stage Entertainment has been responsible for several European productions of Cats. The company produced the musical at the Coliseum Theatre in Madrid from December 2003 to January 2005, with a cast that included Víctor Ullate as Mistoffelees.[210][211] They then staged a Russian-language production at the Moscow Palace of Youth from 2005 to 2006, with a cast that included Ivan Ozhogin as Munkustrap.[212][213] A Dutch production under the same company toured the Netherlands and Belgium from 2006 to 2007,[205][214] featuring several performers in the role of Grizabella including Pia Douwes and Anita Meyer.[215][216] A Paris revival by Stage Entertainment ran at the Théâtre Mogador from October 2015 to July 2016. This production was based on the 2014 London revival and also featured a new song written especially for the French show by Lloyd Webber.[217][218]
An alternative word is English puss (extended as pussy and pussycat). Attested only from the 16th century, it may have been introduced from Dutch poes or from Low German puuskatte, related to Swedish kattepus, or Norwegian pus, pusekatt. Similar forms exist in Lithuanian puižė and Irish puisín or puiscín. The etymology of this word is unknown, but it may have simply arisen from a sound used to attract a cat.[28][29]
