Cats can be infected or infested with viruses, bacteria, fungus, protozoans, arthropods or worms that can transmit diseases to humans.[262] In some cases, the cat exhibits no symptoms of the disease,[263] However, the same disease can then become evident in a human. The likelihood that a person will become diseased depends on the age and immune status of the person. Humans who have cats living in their home or in close association are more likely to become infected, however, those who do not keep cats as pets might also acquire infections from cat feces and parasites exiting the cat's body.[262][264] Some of the infections of most concern include salmonella, cat-scratch disease and toxoplasmosis.[263]

Cats are known for spending considerable amounts of time licking their coats to keep them clean.[147] The cat's tongue has backwards-facing spines about 500 μm long, which are called papillae. These contain keratin which makes them rigid[148] so the papillae act like a hairbrush. Some cats, particularly longhaired cats, occasionally regurgitate hairballs of fur that have collected in their stomachs from grooming. These clumps of fur are usually sausage-shaped and about 2–3 cm (0.8–1.2 in) long. Hairballs can be prevented with remedies that ease elimination of the hair through the gut, as well as regular grooming of the coat with a comb or stiff brush.[147]

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.

Kitten Canon is a classic physics game. Fluffy has found his way into your cannon again, that dang cat just never listens and doesn't care! The only way you can teach it a lesson is by firing that cannon into a field of bombs, spikes, springs, and other awesome obstacles! From the mind of Dan Fleming comes a game that only Dan Fleming could invent: Kitten Canon!! This is a classic launch game with a solid physics engine that allows you to accurately predict where and how fast you can launch Fluffy. Fluffy is a naughty cat so don't worry too much about their well being, it really is Fluffy's own fault for being in the cannon in the first place. Now its your chance to teach Fluffy a lesson in this fun action puzzler!
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.[121] 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.[121] 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.[121] 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.[125]
With a third crash and an evil laugh, the "most wanted" cat Macavity appears. He is the so-called "Napoleon of Crime" who always manages to evade the authorities. Macavity's henchmen capture Old Deuteronomy and take off with the patriarch in tow. As Munkustrap and his troops give chase, Demeter and Bombalurina explain what they know about Macavity ("Macavity: The Mystery Cat"). When they are finished, Macavity returns disguised as Old Deuteronomy, but his cover is blown by Demeter and he ends up in a fight with Munkustrap and Alonzo. Macavity holds his own for a time, but as the rest of the tribe begin to gang up and surround him, he shorts out the stage lights and escapes in the resulting confusion.
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]

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.
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 conserve heat by reducing the flow of blood to their skin and lose heat by evaporation through their mouths. Cats have minimal ability to sweat, with glands located primarily in their paw pads,[105] and pant for heat relief only at very high temperatures[106] (but may also pant when stressed). A cat's body temperature does not vary throughout the day; this is part of cats' general lack of circadian rhythms and may reflect their tendency to be active both during the day and at night.[107]:1
Another poorly understood element of cat hunting behavior is the presentation of prey to human guardians. Ethologist Paul Leyhausen proposed that cats adopt humans into their social group and share excess kill with others in the group according to the dominance hierarchy, in which humans are reacted to as if they are at, or near, the top.[163] Anthropologist and zoologist Desmond Morris, in his 1986 book Catwatching, suggests, when cats bring home mice or birds, they are attempting to teach their human to hunt, or trying to help their human as if feeding "an elderly cat, or an inept kitten".[164][165] Morris's hypothesis is inconsistent with the fact that male cats also bring home prey, despite males having negligible involvement with raising kittens.[161]:153
Influenced by the show's success in Vienna, a German production by Stella Entertainment premiered in April 1986 at the newly-renovated Operettenhaus in Hamburg.[173][179] It closed in January 2001 after 15 years, having played over 6,100 performances to 6.2 million audiences.[179][180] Cats was the first stage production in the country to be mounted without any public funding and was also the first to run for multiple years; its success established the medium as a profitable venture in Germany.[180] The musical was also a huge boost for tourism in Hamburg, particularly the subdivision of St. Pauli where it accounted for 30% of all tourists. The number of overnight visitors to the city increased by over one million per year within the first five years of the show's premiere.[179]
A few attempts to build a cat census have been made over the years, both through associations or national and international organizations (such as the Canadian Federation of Humane Societies's one[245]) and over the Internet,[246][247] but such a task does not seem simple to achieve. General estimates for the global population of domestic cats range widely from anywhere between 200 million to 600 million.[248][249][250][251][252][253]
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]
