Many cultures have negative superstitions about cats. An example would be the belief that a black cat "crossing one's path" leads to bad luck, or that cats are witches' familiars used to augment a witch's powers and skills. The killing of cats in Medieval Ypres, Belgium, is commemorated in the innocuous present-day Kattenstoet (cat parade).[276] In medieval France, cats would be burnt alive as a form of entertainment. According to Norman Davies, the assembled people "shrieked with laughter as the animals, howling with pain, were singed, roasted, and finally carbonized".[277]
Cats and many other animals have a Jacobson's organ in their mouths that is used in the behavioral process of flehmening. It allows them to sense certain aromas in a way that humans cannot. Cats are sensitive to pheromones such as 3-mercapto-3-methylbutan-1-ol,[86] which they use to communicate through urine spraying and marking with scent glands.[87] Many cats also respond strongly to plants that contain nepetalactone, especially catnip, as they can detect that substance at less than one part per billion.[88] About 70–80% of cats are affected by nepetalactone.[89] This response is also produced by other plants, such as silver vine (Actinidia polygama) and the herb valerian; it may be caused by the smell of these plants mimicking a pheromone and stimulating cats' social or sexual behaviors.[90]
The domestic cat is a significant predator of birds. UK assessments indicate they may be accountable for an estimated 64.8 million bird deaths each year.[155] A 2012 study suggests feral cats may kill several billion birds each year in the United States.[222] Certain species appear more susceptible than others; for example, 30% of house sparrow mortality is linked to the domestic cat.[223] In the recovery of ringed robins (Erithacus rubecula) and dunnocks (Prunella modularis), 31% of deaths were a result of cat predation.[224] In parts of North America, the presence of larger carnivores such as coyotes which prey on cats and other small predators reduces the effect of predation by cats and other small predators such as opossums and raccoons on bird numbers and variety.[225] The proposal that cat populations will increase when the numbers of these top predators decline is called the mesopredator release hypothesis.

Back in the present, after Gus exits, Skimbleshanks is seen sleeping in the corner ("Skimbleshanks: The Railway Cat"). He is the cat who is unofficially in charge of the night train to Glasgow. Skimbleshanks is considered vital to the rail operations, as without him "the train can't start". Within his song, a whole steam train engine is assembled out of objects in the junkyard.
Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling/snarling, grunting, and several different forms of meowing.[7] By contrast, feral cats are generally silent.[140]:208 Their types of body language, including position of ears and tail, relaxation of the whole body, and kneading of the paws, are all indicators of mood. The tail and ears are particularly important social signal mechanisms in cats;[141][142] for example, a raised tail acts as a friendly greeting, and flattened ears indicates hostility. Tail-raising also indicates the cat's position in the group's social hierarchy, with dominant individuals raising their tails less often than subordinate animals.[142] Nose-to-nose touching is also a common greeting and may be followed by social grooming, which is solicited by one of the cats raising and tilting its head.[131]
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.
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]

Public attitudes towards feral cats vary widely, ranging from seeing them as free-ranging pets, to regarding them as vermin.[208] One common approach to reducing the feral cat population is termed 'trap-neuter-return', where the cats are trapped, neutered, immunized against diseases such as rabies and the feline Panleukopenia and Leukemia viruses, and then released.[209] Before releasing them back into their feral colonies, the attending veterinarian often nips the tip off one ear to mark it as neutered and inoculated, since these cats may be trapped again. Volunteers continue to feed and give care to these cats throughout their lives. Given this support, their lifespans are increased, and behavior and nuisance problems caused by competition for food are reduced.[206]
Matthew J. Hanson, the creator of Magical Kitties Save the Day, has written RPG material for Kobold Press, Green Ronin Publishing, Dragon and Dungeon Magazines, EN Publishing, Expeditious Retreat Press and more. He also runs a small publishing company called Sneak Attack Press which produces both licensed work, like the silver ENnie Award-winning Broken Earth setting, and original RPGs, like Abstract Dungeon. He lives in Minneapolis with his wife, two cats, and 18-month old son. His son's first word was, in fact, "kitty."

A film adaptation directed by Tom Hooper for Universal Pictures and Working Title Films is scheduled to premiere on 20 December 2019.

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

The 2016 Broadway revival featured new choreography by Andy Blankenbuehler, who introduced more hip hop and cool jazz elements to the movements and dances.[55] Blankenbuehler's choreography for the ensemble numbers did not differ too much from the original by Lynne, but significant changes were made in several solo numbers, including "The Rum Tum Tugger" and "Mr. Mistoffelees".[305]
The origin of the English word cat (Old English catt) and its counterparts in other Germanic languages (such as German Katze), descended from Proto-Germanic *kattōn-, is controversial. It was thought traditionally to be a borrowing from Late Latin cattus, 'domestic cat', from catta (used around 75 AD by Martial),[22][23] compare also Byzantine Greek κάττα, Portuguese and Spanish gato, French chat, Maltese qattus, Lithuanian katė, and Old Church Slavonic kotъ (kot'), among others.[24]
