Encouraged by the reception to the first West End revival, producers began looking to bring Cats back to Broadway in early 2015. The Broadway revival opened on 31 July 2016 at the Neil Simon Theatre. It featured new choreography by Andy Blankenbuehler, with Nunn and Napier from the original creative team returning to direct and design respectively. Scherzinger, who played Grizabella in the 2014 West End revival, had originally agreed to reprise the role on Broadway but later withdrew. Leona Lewis was cast as Grizabella instead and was ultimately succeeded by Mamie Parris in October 2016. The Broadway revival closed on 30 December 2017 after 16 previews and 593 performances.
Cats can synthesize niacin, but their breakdown exceeds the rate that it can be synthesized and thus, have a higher need for it, which can be fulfilled through an animal-based diet. Pyridoxine (vitamin B6) is required in increased amounts seeing as it is needed to produce amino acids. To continue, vitamin B12 is an AAFCO-recommended vitamin essential in the metabolism of carbohydrates and protein and maintains a healthy nervous system, healthy mucous membranes, healthy muscle and heart function and in general, promotes normal growth and development. Choline is also a AAFCO recommended ingredient for kittens, which is important for neurotransmission in the brain and as a component of membrane phospholipids. Biotin is another AAFCO-recommended vitamin to support thyroid and adrenal glands and the reproductive and nervous systems. Kittens also require riboflavin (vitamin B2) for heart health, pantothenic acid (vitamin B5), and folacin.
Cats, like all mammals, need to get linoleic acid, an essential fatty acid, from their diet. Most mammals can convert linoleic acid to arachidonic acid, as well as the omega 3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) through the activity of enzymes, but this process is very limited in cats. The Δ6-desaturase enzyme eventually converts linoleic acid, which is in its salt form linoleate, to arachidonate (salt form of arachidonic acid) in the liver, but this enzyme has very little activity in cats. This means that arachidonic acid is an essential fatty acid for cats as they lack the ability to create required amounts of linoleic acid. Deficiency of arachidonic acid in cats is related to problems in growth, can cause injury and inflammation to skin (e.g. around the mouth) decreased platelet aggregation, fatty liver, increase in birth defects of kittens whose queens were deficient during pregnancy, and reproductive failure in queens. Arachidonic acid can also be metabolized to eicosanoids that create inflammatory responses which are needed to stimulate proper growth and repair mechanisms in the cat.
After the show's closure on Broadway in 2000, Troika Entertainment obtained the touring rights for Cats and launched the show's first non-Equity national company. After a try-out at Harrah's Atlantic City in July 2001, the production toured North America for 11 years from August 2001 to June 2012. Performers in the non-Equity tour included Julie Garnyé as Jennyanydots (2001) and Dee Roscioli as Grizabella (2002). In January 2019, a new North American Equity tour based on the 2016 Broadway revival opened at the Providence Performing Arts Center in Rhode Island, and is scheduled to run through June 2020.
The original London production received mostly rave reviews, with critics hailing it as a watershed moment in British musical theatre. Michael Billington of The Guardian lauded Cats as "an exhilarating piece of total theatre". Billington praised the show's "strong framework" and the ease in which the poems were integrated. He was also very impressed by Lloyd Webber's fitting compositions, Napier's environmental set, Lynne's effective and at times brilliant choreography, and Nunn's "dazzling staging" that makes use of the entire auditorium. The show received similarly glowing reviews from The Sunday Times' Derek Jewell and The Stage's Peter Hepple. Jewell proclaimed it to be "among the most exhilarating and innovative musicals ever staged", while Hepple declared that with Cats, "the British musical has taken a giant leap forward, surpassing in ingenuity and invention anything Broadway has sent us".
Cats are unusually dependent on a constant supply of the amino acid arginine, and a diet lacking arginine causes marked weight loss and can be rapidly fatal. Arginine is an essential additive in cat food because cats have low levels of the enzymes aminotransferase and pyrroline-5-carboxylate which are responsible for the synthesis of ornithine and citrulline in the small intestine. Citrulline would typically go on to the kidneys to make arginine, but because cats have a deficiency in the enzymes that make it, citrulline is not produced in adequate quantities to make arginine. Arginine is essential in the urea cycle in order to convert the toxic component ammonia into urea that can then be excreted in the urine. Because of its essential role, deficiency in arginine results in a buildup of toxic ammonia and leads to hyperammonemia. The symptoms of hyperammonemia include lethargy, vomiting, ataxia, hyperesthesia and can be serious enough to induce death and coma in a matter of days if a cat is being fed an arginine-free diet. The quick onset of these symptoms is due to the fact that diets devoid in arginine will typically still contain all of the other amino acids, which will continue to be catabolized by the body, producing mass amounts of ammonia that very quickly build up with no way of being excreted.
In ancient Egypt, cats were sacred animals, with the goddess Bast often depicted in cat form, sometimes taking on the war-like aspect of a lioness.:220 Killing a cat was absolutely forbidden and the Greek historian Herodotus reports that, whenever a household cat died, the entire family would mourn and shave their eyebrows. Families took their dead cats to the sacred city of Bubastis, where they were embalmed and buried in sacred repositories. The earliest unmistakable evidence of the Greeks having domestic cats comes from two coins from Magna Graecia dating to the mid-fifth century BC showing Iokastos and Phalanthos, the legendary founders of Rhegion and Taras respectively, playing with their pet cats.:57–58
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 »
The scientific name Felis catus for the domestic cat was proposed by Carl Linnaeus in the 10th edition of Systema Naturae published in 1758. Felis catus domesticus was a scientific name proposed by Johann Christian Polycarp Erxleben in 1777. Felis daemon proposed by Konstantin Alekseevich Satunin in 1904 was a black cat specimen from the Transcaucasus, later identified as a domestic cat.
