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]
Cats are obligate carnivores: their physiology has evolved to efficiently process meat, and they have difficulty digesting plant matter.[103] In contrast to omnivores such as rats, which only require about 4% protein in their diet, about 20% of a cat's diet must be protein.[103] A cat's gastrointestinal tract is adapted to meat eating, being much shorter than that of omnivores and having low levels of several of the digestive enzymes needed to digest carbohydrates.[111] These traits severely limit the cat's ability to digest and use plant-derived nutrients, as well as certain fatty acids.[111] Despite the cat's meat-oriented physiology, several vegetarian or vegan cat foods have been marketed that are supplemented with chemically synthesized taurine and other nutrients, in attempts to produce a complete diet. Some of these products still fail to provide all the nutrients cats require,[112] and diets containing no animal products pose the risk of causing severe nutritional deficiencies.[113]
To keep up with your kitten’s appetite, you’ll want to establish a daily feeding routine. The best way to ensure that you’re not under or over-feeding your kitten is to consult with you veterinarian about how much and how often to feed. At 3 to 6 moths of age, most vets recommend feeding your kitten three times a day. Once he’s reached six months, you can scale it back to twice a day. Keep stocking your pantry with kitten food until your baby reaches adulthood, 9 to12 months old. In addition, don’t forget to keep his water bowl fresh and filled at all times. But hold the milk. Contrary to popular belief, milk is not nutritionally sufficient for kittens and can give them diarrhea.

The original London production received mostly rave reviews, with critics hailing it as a watershed moment in British musical theatre.[295] 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.[296] 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",[295] 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".[297]

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]


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]
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]

The London production ran for 21 years and 8,949 performances, while the Broadway production ran for 18 years and 7,485 performances, making Cats the longest-running musical in both theatre districts for a number of years. As of 2019, it remains the sixth-longest-running West End show and the fourth-longest-running Broadway show. Cats has since been revived in the West End twice and on Broadway once. It has also been translated into multiple languages and performed around the world many times. Long-running foreign productions include a 15-year run at the Operettenhaus in Hamburg that played over 6,100 performances, as well as an ongoing run in a purpose-built theatre in Japan that has played over 10,000 performances since it opened in 1983.


Nobel laureate and Pulitzer Prize-winner Toni Morrison, the author of such acclaimed works as "Song of Solomon," "Beloved," "Jazz," and "Love," died on Monday, August 5, 2019 at the age of 88. In this profile for "CBS Sunday Morning" which aired on April 4, 2004, the writer talked with correspondent Martha Teichner about her youth and education, and about the two most important things in her life: to mother her children, and to write.
Domestic cats are generally smaller than wildcats in both skull and limb measurements.[58] Adult domestic cats typically weigh between 4 and 5 kg (9 and 10 lb),[48] although many breeds have a wide range of sizes, with male American Shorthairs ranging from 3 to 7 kg (7 to 20 lb).[59] Some cat breeds, such as the Maine Coon, occasionally exceed 11 kg (24 lb). Very small cats, less than 2 kg (4 lb), have been reported.[60] The world record for the largest cat is 21 kg (50 lb).[61][self-published source] The smallest adult cat ever officially recorded weighed around 1 kg (2 lb).[61] Feral cats tend to be lighter, as they have more limited access to food than house cats. The average feral adult male weighs 4 kg (9 lb), and the average adult female 3 kg (7 lb).[62] Cats average about 23–25 cm (9–10 in) in height and 46 cm (18 in) in head/body length (males being larger than females), with tails averaging 30 cm (12 in) in length.[63]
