Free-fed feral cats and house cats tend to consume many small meals in a single day, although the frequency and size of meals varies between individuals.[133] Cats use two hunting strategies, either stalking prey actively, or waiting in ambush until an animal comes close enough to be captured.[160] Although it is not certain, the strategy used may depend on the prey species in the area, with cats waiting in ambush outside burrows, but tending to actively stalk birds.[161]:153
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 fourth national company, Cats National IV, toured the United States for 13 years from March 1987 to December 1999.[117] It overtook the first national tour of Oklahoma! in November 1997 to become the longest-running tour in theatre history, and played its 5,000th performance in July 1999.[118] Notable performers in the fourth tour included Amelia Marshall as Sillabub (1988), Jan Horvath as Grizabella (1990), Bryan Batt as Munkustrap (1991–1992), Jennifer Cody as Rumpleteazer (1992), David Hibbard as Rum Tum Tugger (1992–1993), Natalie Toro as Grizabella (1992, 1997), Christopher Gattelli as Mistoffelees (1993), John Treacy Egan as Old Deuteronomy (1993–1994), J. Robert Spencer as Rum Tum Tugger (1995), Bart Shatto as Bustopher Jones/Gus/Growltiger (1996), Linda Balgord as Grizabella (1998), Andy Karl as Rum Tum Tugger (1998), and Lena Hall as Demeter (1998).[117] By June 1997, the North American touring companies had grossed over $400 million.[88]
In Magical Kitties Save the Day, one player — known as the Game Master (GM) — has a very special role. They describe the world in which the magical kitties live to the other players and, when the kitties take action, they use the rules of the game to figure out what happens next. Magical Kitties also includes “Magical Kitties & The Game Master’s First Adventure.” Just as The Big Adventure will walk new players through how to play the game, “The Game Master’s First Adventure” will walk first-time Game Masters through how to run the game for their friends and family.
Napier began designing the set in November 1980, wanting "a place where cats might congregate together, which also included maximum room for dancing".[93] The set of Cats consists of a junkyard filled with oversized props to give the illusion that the cast are the size of actual cats;[94] it remains the same throughout the show without any scene changes. Over 2,500 of these scaled-up props were used to fill the whole auditorium in the original Broadway production.[16][95]
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.
Spaying or neutering increases life expectancy: one study found neutered male cats live twice as long as intact males, while spayed female cats live 62% longer than intact females.[188]:35 Having a cat neutered confers health benefits, because castrated males cannot develop testicular cancer, spayed females cannot develop uterine or ovarian cancer, and both have a reduced risk of mammary cancer.[193]
Finally, the Jellicle patriarch, Old Deuteronomy, arrives before the tribe ("Old Deuteronomy"). He is a wise old cat who "has lived many lives" and is tasked with choosing which Jellicle will go to the Heaviside Layer every year. The cats put on a play for Old Deuteronomy ("The Awefull Battle of the Pekes and the Pollicles"), telling a story about two dog tribes clashing in the street and subsequently being scared away by the Great Rumpus Cat. A sombre moral from Old Deuteronomy is interrupted by a second loud crash, presumably from Macavity, which sends the alarmed cats scurrying. After a quick patrol for Macavity, Old Deuteronomy deems it a false alarm and summons the cats back as the main celebration begins ("The Jellicle Ball"), in which the cats sing and display their "Terpsichorean powers".
The cat skull is unusual among mammals in having very large eye sockets and a powerful specialized jaw.[66]:35 Within the jaw, cats have teeth adapted for killing prey and tearing meat. When it overpowers its prey, a cat delivers a lethal neck bite with its two long canine teeth, inserting them between two of the prey's vertebrae and severing its spinal cord, causing irreversible paralysis and death.[67] Compared to other felines, domestic cats have narrowly spaced canine teeth relative to the size of their jaw, which is an adaptation to their preferred prey of small rodents, which have small vertebrae.[67] The premolar and first molar together compose the carnassial pair on each side of the mouth, which efficiently shears meat into small pieces, like a pair of scissors. These are vital in feeding, since cats' small molars cannot chew food effectively, and cats are largely incapable of mastication.[66]:37 Although cats tend to have better teeth than most humans, with decay generally less likely because of a thicker protective layer of enamel, a less damaging saliva, less retention of food particles between teeth, and a diet mostly devoid of sugar, they are nonetheless subject to occasional tooth loss and infection.[68]
Within the first 2 days after birth, kittens acquire passive immunity from their mother’s milk.[30] Milk within the first few days of parturition is called colostrum, and contains high concentrations of immunoglobulins.[30] These include immunoglobulin A and immunoglobulin G which cross the intestinal barrier of the neonate.[29] The immunoglobulins and growth factors found in the colostrum begin to establish and strengthen the weak immune system of the offspring.[31] Kittens are able to chew solid food around 5–6 weeks after birth, and it is recommended that 30% of their diet should consist of solid food at this time.[32] The kitten remains on the mother’s milk until around eight weeks of age when weaning is complete and a diet of solid food is the primary food source.[23]
Similar to the original London staging, the set of the 1,200-capacity CATS Theatre is built on a revolving stage floor such that during the overture, the stage and sections of the stalls revolve approximately 180 degrees into place.[160][166] In 1998, the Japanese production underwent major revisions to the choreography, staging and costume designs.[167] Following further revisions in 2018,[168] the current incarnation features 25 named cats, including both Jemima and Sillabub (who have evolved into two separate characters), and an original character named Gilbert.[169]
Cats introduced a marketing strategy that set the template for subsequent megamusicals. Early advertisements for the musical did not feature traditional pull quotes (despite many positive reviews) or any of the cast, focusing instead on branding the show itself as the star. It did this by adopting — and then aggressively promoting — a single recognisable image (the cat's-eyes logo) as the face of the show.[321] The cat's-eyes logo was the first globally marketed logo in musical theatre history,[88] and was paired with a tagline ("now and forever") to create what The Daily Telegraph called "one of musical theatre's greatest posters".[322] Such branding emblems proved equally effective for later megamusicals, as seen with the waif Cosette for Les Misérables and the Phantom's mask for The Phantom of the Opera. This advertising method had the additional effect of diminishing the importance of critical reviews, popularising the so-called "critic-proof" status of megamusicals.[321]
The musical was scheduled to open on 30 April 1981, with previews starting on 22 April. Shortly before tickets went on sale in mid-February, Nunn revealed to the alarmed producers that he was struggling to write the script for the musical. Despite still having no established book or score, rehearsals began on 9 March 1981 in a church hall in Chiswick, London. The original music director, Chris Walker, became so frustrated with the unfinished score that he quit by lunchtime and was replaced by the film conductor Harry Rabinowitz.[20] The situation improved later that day when Lloyd Webber, Mackintosh and Nunn met with Stilgoe, a musician known for his ability to improvise lyrics on the spot, in hopes that Stilgoe could write an opening song for the musical. By the next evening, Stilgoe had produced a draft for "Jellicle Songs for Jellicle Cats".[21] However, "Memory", an 11 o'clock number for Grizabella that Nunn insisted the show needed as its "emotional centre",[22] still had no lyrics at this point. Lloyd Webber's former writing partner Tim Rice was brought in to write a lyric for the song, but his version was rejected by Nunn for being too depressing. The lyrics for "Memory" were not completed by Nunn until well into the previews.[23]

In 2003, the International Commission on Zoological Nomenclature (ICZN) fixed the scientific name for the wildcat as F. silvestris. The same commission ruled that the domestic cat is a distinct taxon Felis catus.[40][41] Following results of phylogenetic research, the domestic cat was considered a wildcat subspecies F. silvestris catus in 2007.[42][43]
