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 scientific name Felis catus for the domestic cat was proposed by Carl Linnaeus in the 10th edition of Systema Naturae published in 1758.[1][2] Felis catus domesticus was a scientific name proposed by Johann Christian Polycarp Erxleben in 1777.[3] Felis daemon proposed by Konstantin Alekseevich Satunin in 1904 was a black cat specimen from the Transcaucasus, later identified as a domestic cat.[38][39]

Since kitten diets are very high in calories, ingredients must be implemented to ensure adequate digestion and utilization of these calories. Choline chloride is an ingredient that maintains fat metabolism.[42] Biotin and niacin are also active in the metabolism of fats, carbs and protein.[42] Riboflavin is also necessary for the digestion of fats and carbohydrates.[42] These are the main metabolism aids incorporated into kitten diets to ensure nutrient usage is maximized.
Atlas Games has been creating games for nearly three decades. We have launched, completed, and fulfilled four previous Kickstarter projects: Feng Shui 2, Unknown Armies 3, the third edition of Over the Edge, and the exciting card game Cogs & Commissars. While every project comes with its own special risks and demands, we’re confident that Magical Kitties Save the Day will be every bit as successful in its production and fulfillment as these other games.
Perhaps the best known element of cats' hunting behavior, which is commonly misunderstood and often appalls cat owners because it looks like torture, is that cats often appear to "play" with prey by releasing it after capture. This behavior is due to an instinctive imperative to ensure that the prey is weak enough to be killed without endangering the cat.[162] This behavior is referred to in the idiom "cat-and-mouse game" or simply "cat and mouse".
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.
In the original London production, Mungojerrie and Rumpleteazer were characters in their own right and sang their eponymous song themselves as a singsong-style duet. When the show transferred to Broadway, the song was instead sung in the third-person, with Mungojerrie and Rumpleteazer as puppets being magically controlled by Mr. Mistoffelees. Their number was also rewritten to be faster and more upbeat, alternating between vaudeville-style verses and a "manic patter" section. Eventually, the Broadway version of the song was rewritten to allow Mungojerrie and Rumpleteazer to once again sing their own song as full characters.[388]
About 250 heritable genetic disorders have been identified in cats, many similar to human inborn errors.[286] The high level of similarity among the metabolism of mammals allows many of these feline diseases to be diagnosed using genetic tests that were originally developed for use in humans, as well as the use of cats as animal models in the study of the human diseases.[287][288]
Encouraged by the reception to the first West End revival, producers began looking to bring Cats back to Broadway in early 2015.[108] The Broadway revival opened on 31 July 2016 at the Neil Simon Theatre.[109] It featured new choreography by Andy Blankenbuehler, with Nunn and Napier from the original creative team returning to direct and design respectively.[110] Scherzinger, who played Grizabella in the 2014 West End revival, had originally agreed to reprise the role on Broadway but later withdrew.[111] Leona Lewis was cast as Grizabella instead and was ultimately succeeded by Mamie Parris in October 2016.[64] The Broadway revival closed on 30 December 2017 after 16 previews and 593 performances.[109]
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]
It was long thought that cat domestication was initiated in Egypt, because cats in ancient Egypt were venerated from around 3100 BC.[11][12] However, the earliest indication for the taming of an African wildcat (F. lybica) was found in Cyprus, where a cat skeleton was excavated close by a human Neolithic grave dating to around 7500 BC.[13] African wildcats were probably first domesticated in the Near East.[14] The leopard cat (Prionailurus bengalensis) was tamed independently in China around 5500 BC, though this line of partially domesticated cats leaves no trace in the domestic cat populations of today.[15][16]
