The domestic cat is a member of the Felidae, a family that had a common ancestor about 10–15 million years ago.[45] The genus Felis diverged from the Felidae around 6–7 million years ago.[46] Members of this genus include the jungle cat (F. chaus), European wildcat (F. silvestris), African wildcat (F. lybica), Chinese mountain cat (F. bieti), sand cat (F. margarita) and black-footed cat (F. nigripes).[47] Results of phylogenetic research confirm that these wild Felis species evolved through sympatric or parapatric speciation, whereas the domestic cat evolved through artificial selection.[48]

The original staging of Cats at the New London Theatre was considered revolutionary[85] and "one of the first truly immersive theatrical experiences".[34] Instead of a conventional proscenium, the theatre was quasi-in-the-round with a central revolving stage.[15][86] Nunn and Napier had sought to create "an environment rather than a set",[17] and around $900,000 was spent remodelling the New London in preparation for the show.[9] This included mounting sections of the stalls onto the theatre's 60 ft (18 m)[87] revolve such that the audience moved along with the stage.[16] When the show was brought to Broadway, the Winter Garden Theatre was given a similar $2 million makeover;[88] its proscenium stage was converted into a thrust, and a part of its roof was torn through to allow for the effects of Grizabella's ascension to the Heaviside Layer.[89]
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.[115] 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.[116] 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.[citation needed]
The musical's fantasy setting and disregard for verisimilitude allowed for groundbreaking experimentations in lighting and audio technology. The original London and Broadway productions featured David Hersey's pioneering use of automated lighting to produce kaleidoscopic landscapes and complicated optical effects. Hersey also used light in an "architectural manner", with fast-changing configurations to spotlight different performers in rapid succession. This dynamic shifting of the audience's perspective created an effect similar to that of fast cutting in film editing.[16] The original London production of Cats was also the first known instance in which an entire cast was individually outfitted with radio microphones.[327] The departure from shared ambient microphones meant that the show did not have to depend on the acoustics and architectural design of the theatrical venue, and enabled the sound designer to achieve cinematic levels of sound amplification and studio-quality audio in live theatre.[328] This practice transformed sound design and has since become the norm in live theatre.[327]

One of the first things you should do with your new cat, if not the very first, is take him in for an exam. This trip is almost as important for the owner as it is the kitten, because it not only tests for health issues like birth defects, parasites, and feline leukemia, but it allows you to ask those all important questions including advice on litterbox training your kitten.

An alternative word is English puss (extended as pussy and pussycat). Attested only from the 16th century, it may have been introduced from Dutch poes or from Low German puuskatte, related to Swedish kattepus, or Norwegian pus, pusekatt. Similar forms exist in Lithuanian puižė and Irish puisín or puiscín. The etymology of this word is unknown, but it may have simply arisen from a sound used to attract a cat.[28][29]
