Most of the lyrics in Cats were taken from Old Possum's Book of Practical Cats with very minor alterations. Supplementary verses from unpublished poems by Eliot were adapted for "Grizabella: The Glamour Cat" and "Journey to the Heaviside Layer", while the song "The Moments of Happiness" was taken from a passage in Eliot's The Dry Salvages. Cats director Trevor Nunn and lyricist Richard Stilgoe provided the remaining lyrics, namely for the opening number "Jellicle Songs for Jellicle Cats" and the most famous song from the musical "Memory". The former was written by Nunn and Stilgoe and was modelled after an unpublished poem by Eliot titled "Pollicle Dogs and Jellicle Cats", while the latter was written by Nunn based on another Eliot poem titled "Rhapsody on a Windy Night".[1]
Several natural behaviors and characteristics of wildcats may have preadapted them for domestication as pets. These traits include their small size, social nature, obvious body language, love of play and relatively high intelligence.[57]:12–17 Captive Leopardus cats may also display affectionate behavior toward humans, but have not been domesticated.[54]
Steven Spielberg's Amblimation had planned an animated adaptation of the musical in the 1990s. The film was to be set in war-torn London during World War II, but the project was abandoned with the studio's closure in 1997.[290] The following year, a direct-to-video film was released. The film was directed by David Mallet and was shot at the Adelphi Theatre in London. It starred Elaine Paige as Grizabella, John Mills as Gus, Ken Page as Old Deuteronomy, and Michael Gruber as Munkustrap.[291]

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 also features an unusual amount of "group-description" numbers. According to musicologist Jessica Sternfeld, such numbers are usually relegated to the prologue and nothing more, as seen in "Another Op'nin', Another Show" from Kiss Me, Kate and "Tradition" from Fiddler on the Roof. Cats on the other hand features four Jellicle-defining songs: "Jellicle Songs for Jellicle Cats", "The Naming of Cats", "The Jellicle Ball" and "The Ad-Dressing of Cats". These numbers allow the cats to celebrate their tribe and species as a whole, in between the ones that celebrate individual members.[80]
Kittens develop very quickly from about two weeks of age until their seventh week. Their coordination and strength improves. They play-fight with their litter-mates and begin to explore the world outside the nest or den. They learn to wash themselves and others as well as play hunting and stalking games, showing their inborn ability as predators. These innate skills are developed by the kittens' mother or other adult cats, who bring live prey to the nest. Later, the adult cats demonstrate hunting techniques for the kittens to emulate.[11] As they reach three to four weeks old, the kittens are gradually weaned and begin to eat solid food, with weaning usually complete by six to eight weeks.[12] Kittens generally begin to lose their baby teeth around three months of age, and have a complete set of adult teeth by nine months.[13] Kittens live primarily on solid food after weaning, but usually continue to suckle from time to time until separated from their mothers. Some mother cats will scatter their kittens as early as three months of age, while others continue to look after them until they approach sexual maturity.[14]
Then, as Rum Tum Tugger's song fades, a shabby old grey cat stumbles out wanting to be reconciled; it is Grizabella. All the cats back away from her in fear and disgust and explain her unfortunate state ("Grizabella: The Glamour Cat"). Grizabella leaves and the music changes to a cheerful upbeat number as Bustopher Jones, a fat cat in "a coat of fastidious black", is brought to the stage ("Bustopher Jones: The Cat About Town"). Bustopher Jones is among the elite of the cats, and visits prestigious gentlemen's clubs. Suddenly, a loud crash startles the tribe and the cats run offstage in fright. Hushed giggling sounds signal the entrance of Mungojerrie and Rumpleteazer, a pair of near-identical cats. They are mischievous petty burglars who enjoy causing trouble around their human neighbourhood ("Mungojerrie and Rumpleteazer"). After they finish, they are caught off-guard and confronted by the rest of the cats.
Vitamin D3 is a dietary requirement for cats as they lack the ability to synthesize vitamin D3 from sunlight.[123] Cats obtain high levels of the enzyme 7-dehydrocholestrol delta 7 reductase which causes immediate conversion of vitamin D3 from sunlight to 7-dehydrocholesterol.[124] This fat soluble vitamin is required in cats for bone formation through the promotion of calcium retention, along with nerve and muscle control through absorption of calcium and phosphorus.[124]
Though it’s not something you have any control over, your kitten’s age is more than just a number. In fact, it’s crucial that you learn it. Kittens have very specific developmental needs for the first 10 weeks of their lives in terms of nourishment, warmth, socialization, and excretion. For this reason, most breeders and shelters typically wait until their kittens are of age before they’re put up for adoption. If you, by chance, find yourself in a situation where you need to care for an orphaned kitten under 10 weeks old, consult your vet for special instructions.
Another unusual feature is that the cat cannot produce taurine,[note 1] with a deficiency in this nutrient causing macular degeneration, wherein the cat's retina slowly breaks down, causing irreversible blindness.[103] This is due to the hepatic activity of cystinesulfinic acid decarboxylase being low in cats. This limits the ability of cats to biosynthesize the taurine they need from its precursor, the amino acid cysteine, which ultimately results in inadequate taurine production needed for normal function. Deficiencies in taurine result in compensated function of feline cardiovascular and reproductive systems. These abnormalities can also be accompanied by developmental issues in the central nervous system along with degeneration of the retina.[118]
Cats are ready to go to new homes at about 12 weeks of age, when they are ready to leave their mother.[184] They can be surgically sterilized (spayed or castrated) as early as 7 weeks to limit unwanted reproduction.[185] This surgery also prevents undesirable sex-related behavior, such as aggression, territory marking (spraying urine) in males and yowling (calling) in females. Traditionally, this surgery was performed at around six to nine months of age, but it is increasingly being performed before puberty, at about three to six months.[186] In the US, about 80% of household cats are neutered.[187]
Some of the same factors that have promoted adaptive radiation of island avifauna over evolutionary time appear to promote vulnerability to non-native species in modern time. The susceptibility of many island birds is undoubtedly due to evolution in the absence of mainland predators, competitors, diseases, and parasites, in addition to lower reproductive rates and extended incubation periods.[231] The loss of flight, or reduced flying ability is also characteristic of many island endemics.[232] These biological aspects have increased vulnerability to extinction in the presence of introduced species, such as the domestic cat.[233] Equally, behavioral traits exhibited by island species, such as "predatory naivety"[234] and ground-nesting,[231] have also contributed to their susceptibility.
Kittens are so cute, it’s understandable that cat owners sometimes wish their kittens could stay kittens forever. This is the when you, as the pet parent, lay the foundation for your cat’s future health and behavior. Not to mention, it’s the stage where you have to decide what food to buy, what vet to visit, and where to place the litterbox. Fortunately, all of your hard work during these first few months is compensated by loads of snuggling and adorability.
"It was the custom to burn a basket, barrel, or sack full of live cats, which was hung from a tall mast in the midst of the bonfire; sometimes a fox was burned. The people collected the embers and ashes of the fire and took them home, believing that they brought good luck. The French kings often witnessed these spectacles and even lit the bonfire with their own hands. In 1648 Louis XIV, crowned with a wreath of roses and carrying a bunch of roses in his hand, kindled the fire, danced at it and partook of the banquet afterwards in the town hall. But this was the last occasion when a monarch presided at the midsummer bonfire in Paris. At Metz midsummer fires were lighted with great pomp on the esplanade, and a dozen cats, enclosed in wicker cages, were burned alive in them, to the amusement of the people. Similarly at Gap, in the department of the Hautes-Alpes, cats used to be roasted over the midsummer bonfire."[278]
Like almost all members of the Felidae, cats have protractable and retractable claws.[71] In their normal, relaxed position, the claws are sheathed with the skin and fur around the paw's toe pads. This keeps the claws sharp by preventing wear from contact with the ground and allows the silent stalking of prey. The claws on the fore feet are typically sharper than those on the hind feet.[72] Cats can voluntarily extend their claws on one or more paws. They may extend their claws in hunting or self-defense, climbing, kneading, or for extra traction on soft surfaces. Most cats have five claws on their front paws, and four on their rear paws.[73] The fifth front claw (the dewclaw) is proximal to the other claws. More proximally is a protrusion which appears to be a sixth "finger". This special feature of the front paws, on the inside of the wrists, is the carpal pad, also found on the paws of big cats and dogs. It has no function in normal walking, but is thought to be an antiskidding device used while jumping. Some breeds of cats are prone to polydactyly (extra toes and claws).[73] These are particularly common along the northeast coast of North America.[74]

After the overture, the cats gather on stage and describe the Jellicle tribe and its purpose ("Jellicle Songs for Jellicle Cats"). The cats (who break the fourth wall throughout the show) then notice that they are being watched by a human audience, and proceed to explain how the different cats of the tribe are named ("The Naming of Cats"). This is followed by a ballet solo performed by Victoria to signal the beginning of the Jellicle Ball ("The Invitation to the Jellicle Ball"). At this moment, Munkustrap, the show's main narrator, explains that tonight the Jellicle patriarch Old Deuteronomy will make an appearance and choose one of the cats to be reborn into a new life on the Heaviside Layer.
It's okay for a black man to be seen, and date, as long as it's not spoken outright, but as soon as a black woman does it, I'm a sellout, trying to get to something better with white men. It outrages me that I can't be myself without idiots trying to bring me down. I didn't say I don't like black men, I just said what I prefer . . . and for those who think I just started doing this, I've been ... See more »
In the original London production, Mungojerrie and Rumpleteazer were characters in their own right and sang their eponymous song themselves as a singsong-style duet. When the show transferred to Broadway, the song was instead sung in the third-person, with Mungojerrie and Rumpleteazer as puppets being magically controlled by Mr. Mistoffelees. Their number was also rewritten to be faster and more upbeat, alternating between vaudeville-style verses and a "manic patter" section. Eventually, the Broadway version of the song was rewritten to allow Mungojerrie and Rumpleteazer to once again sing their own song as full characters.[388]
Felines are carnivores and have adapted to animal-based diets and low carbohydrate inclusion. Kittens are categorized in a growth life stage, and have high energy and protein requirements.[23] When feeding a kitten, it is often recommended to use highly digestible ingredients and various components to aid in development in order to produce a healthy adult.[24] In North America, diets certified by the Association of American Feed Control Officials (AAFCO) are accepted as adequate nutrition, thus kitten diets should be AAFCO approved to ensure full supplementation.[25] Key components of the diet are high fat content to meet caloric requirements of growth, high protein to meet requirements for muscle growth as well as supplementation of certain nutrients such as docosahexaenoic acid to benefit the development of the brain and optimization of cognition.[26]

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.
Among domestic cats, males are more likely to fight than females.[149] Among feral cats, the most common reason for cat fighting is competition between two males to mate with a female. In such cases, most fights are won by the heavier male.[150] Another common reason for fighting in domestic cats is the difficulty of establishing territories within a small home.[149] Female cats also fight over territory or to defend their kittens. Neutering will decrease or eliminate this behavior in many cases, suggesting that the behavior is linked to sex hormones.[151]
November 1985 saw the premiere of a Norwegian-language production at Det Norske Teatret in Oslo. It closed in January 1987 and included performers such as Øivind Blunck, Brit Elisabeth Haagensli and Øystein Wiik.[118][193] Jorma Uotinen directed and choreographed a Finnish production at the Helsinki City Theatre that ran for over two years from September 1986 to December 1988, and featured Monica Aspelund as Grizabella, Heikki Kinnunen as Gus, and Kristiina Elstelä as Jennyanydots/Griddlebone.[194] A Swedish version of the musical opened in 1987 at the Chinateatern in Stockholm. The production was seen by 326,000 audiences before it transferred to the Scandinavium in Gothenburg two years later.[195]

Felines are natural carnivores and do not intentionally consume large quantities of carbohydrates. The domestic cat's liver has adapted to the lack of carbohydrates in the diet by using amino acids to produce glucose to fuel the brain and other tissues.[39] Studies have shown that carbohydrate digestion in young kittens is much less effective than that of a mature feline with a developed gastrointestinal tract.[40] Highly digestible carbohydrates can be found in commercial kitten food as a source of additional energy as well as a source of fiber to stimulate the immature gut tissue. Soluble fibre such as beet pulp is a common ingredient used as a fibrous stool hardener and has been proven to strengthen intestinal muscles and to thicken the gut mucosal layer to prevent diarrhea.[41]

To aid with navigation and sensation, cats have dozens of movable whiskers (vibrissae) over their body, especially their faces. These provide information on the width of gaps and on the location of objects in the dark, both by touching objects directly and by sensing air currents; they also trigger protective blink reflexes to protect the eyes from damage.[66]:47
