The term "'''big cat'''" is typically used to refer to any of the five living members of the genus ''[[Panthera]]'', namely the [[tiger]], [[lion]], [[jaguar]], [[leopard]], and [[snow leopard]], as well as the non-[[Pantherinae|pantherine]] [[cheetah]] and [[cougar]].<ref>{{Cite journal |last1=Davis, B.W. |last2=Li, G. |last3=Murphy, W.J. |year=2010 |title=Supermatrix and species tree methods resolve phylogenetic relationships within the big cats, ''Panthera'' (Carnivora: Felidae) |journal=Molecular Phylogenetics and Evolution |volume=56 |issue=1 |pages=64−76 |doi=10.1016/j.ympev.2010.01.036 |pmid=20138224|bibcode=2010MolPE..56...64D }}</ref><ref>{{Cite book |last1=Turner, Alan |url=https://books.google.com/books?id=66mRJSxIAfoC |title=The Big Cats and Their Fossil Relatives |last2=Anton, Mauricio |date=1997 |publisher=Columbia University Press |isbn=978-0-231-10228-5 |edition=Illustrated |pages=79–81 |oclc=34283113}}</ref>
All cats descend from the ''[[Felidae]]'' family, sharing similar musculature, cardiovascular systems, skeletal frames, and behaviour. Both the cheetah and cougar differ physically from fellow big cats, and to a greater extent, other [[Cat|small cats]]. As [[Carnivore|obligate carnivores]], big cats are considered [[apex predator]]s, topping their [[food chain]] without natural predators of their own.<ref>{{Cite journal |last=Balme |first=G. |year=2005 |title=Counting Cats |url=https://www.panthera.org/sites/default/files/Balme_2005_Counting_cats_0.pdf |journal=Africa Geographic |issue=13 |pages=36−43 |archive-url=https://web.archive.org/web/20150913005827/https://www.panthera.org/sites/default/files/Balme_2005_Counting_cats_0.pdf |archive-date=2015-09-13}}</ref><ref>{{Cite journal |last1=Ordiz |first1=Andrés |last2=Bischof |first2=Richard |last3=Swenson |first3=Jon E. |date=2013-12-01 |title=Saving large carnivores, but losing the apex predator? |url=https://www.sciencedirect.com/science/article/pii/S0006320713003418 |journal=Biological Conservation |language=en |volume=168 |pages=128–133 |doi=10.1016/j.biocon.2013.09.024 |bibcode=2013BCons.168..128O |issn=0006-3207 |hdl-access=free |hdl=11250/2492589}}</ref> Native ranges include the [[Americas]], [[Africa]], and [[Asia]]; the ranges of the leopard and tiger also extend into [[Europe]], specifically in [[Russia]].<ref name="iucn-p.pardus" />

The tiger then evolved into a unique species towards the end of the [[Pliocene]] epoch, approximately 3.2 Ma. The ancestor of the lion, leopard, and jaguar split from other big cats from 4.3–3.8 Ma.

==Description and abilities==
===Roaring===
The ability to [[Roar (vocalization)|roar]] comes from an elongated and specially adapted [[larynx]] and [[hyoid bone|hyoid apparatus]].<ref>{{Cite journal |last1=Weissengruber |first1=GE |last2=G Forstenpointner |last3=G Peters |last4=A Kübber-Heiss |last5=WT Fitch |date=September 2002 |title=Hyoid apparatus and pharynx in the lion (Panthera leo), jaguar (Panthera onca), tiger (Panthera tigris), cheetah (Acinonyx jubatus), liger (Panthera leo × Panthera tigris), Tigon (Panthera tigris x Panthera leo) and the domestic cat. (Felis silvestris f. catus) |journal=Journal of Anatomy |volume=201 |issue=3 |pages=195–209 |doi=10.1046/j.1469-7580.2002.00088.x |pmc=1570911 |pmid=12363272}}</ref> The larynx is attached to the hyoid bone that is hanging from a sequence of bones. This sequence of bones the hyoid hangs from are tympanohyal, stylohyal, epihyal, and ceratohyal; these are located in the mandible and skull.<ref>{{Cite journal |last=Hast |first=M H |date=April 1989 |title=The larynx of roaring and non-roaring cats. |journal=Journal of Anatomy |volume=163 |pages=117–121 |issn=0021-8782 |pmc=1256521 |pmid=2606766}}</ref>  In the larynx, there are vocal folds that produce the structure needed to stretch the ligament to a length that creates the roar effect. This tissue is made of thick collagen and elastic fiber that becomes denser as it approaches the epithelial mucosal lining.<ref>{{Cite journal |last1=Erickson-DiRenzo |first1=Elizabeth |last2=Sivasankar |first2=M. Preeti |last3=Thibeault |first3=Susan L. |date=2014-12-15 |title=Utility of cell viability assays for use with ex vivo vocal fold epithelial tissue |journal=The Laryngoscope |volume=125 |issue=5 |pages=E180–E185 |doi=10.1002/lary.25100 |issn=0023-852X |pmc=4414688 |pmid=25511412}}</ref> When this large pad folds it creates a low natural frequency, causing the cartilage walls of the larynx to vibrate. When it begins to vibrate the sound moves from a high to low air resistance which makes the roaring.
The lion's larynx is the longest, giving it the most robust roar. The roar in good conditions can be heard 8 or even 10&nbsp;km ({{convert|8|or|10|km|0|disp=out}}) away.<ref name="Darling2000">{{Cite book |last=Kathy Darling |url=https://books.google.com/books?id=qaoK0ykgmwQC |title=Lions |date=1 January 2000 |publisher=Lerner Publications |isbn=978-1-57505-404-9}}</ref> All five extant members of the genus ''Panthera'' contain this elongated hyoid but owing to differences in the larynx the [[snow leopard]] cannot roar. Unlike the roaring cats in their family, the snow leopard is distinguished by the lack of a large pad of fibro-elastic tissue that allows for a large vocal fold.

===Conservation===
{{Hatnote|For the population of the big cats, see [[List of carnivorans by population]]}}
An [[animal sanctuary]] provides a refuge for animals to live out their natural lives in a protected environment. Usually, these animal sanctuaries are the organizations which provide a home to big cats whose private owners are no longer able or willing to care for their big cats. However, the use of the word ''sanctuary'' in an organization's name is by itself no guarantee that it is a true animal sanctuary in the sense of a refuge. To be accepted by the [[United States Fish and Wildlife Service]] (FWS) as a bona fide animal sanctuary and to be eligible for an exemption from the prohibition of interstate movement of big cats under the Captive Wildlife Safety Act (CWSA), organizations must meet the following criteria:<ref>{{Cite web |title=Captive Wildlife Safety Act - What Big Cat Owners Need to Know |url=http://www.fws.gov/le/pdf/CaptiveWildlifeSafetyActFactsheet.pdf |publisher=U.S. Fish and Wildlife Service, Office of Law Enforcement}}</ref>
*Must be a non-profit entity that is tax-exempt under section 501(a) of the Internal Revenue Code
*Cannot engage in commercial trade in big cat species, including their offspring, parts, and products made from them
*Cannot breed big cats
*Cannot allow direct contact between big cats and the public at their facilities
*Must keep records of transactions involving covered cats
*Must allow the service to inspect their facilities, records, and animals at reasonable hours

Certain protected areas exist that shelter large and exceptionally visible populations of [[African leopard]]s, lions and cheetahs, such as Botswana's [[Chobe National Park|Chobe]], Kenya's [[Masai Mara]], and Tanzania's [[Serengeti National Park|Serengeti]]; outside these conservation areas, hunting poses the dominant threat to large carnivores.<ref>{{Cite journal |last=Hunter |first=Luke |date=June 2004 |title=Carnivores in Crisis: The Big Cats |url=http://www.panthera.org/documents/HunterAfGeo2004CarnivoresInCrisisPart1.pdf |journal=Africa Geographic |pages=28–41 |archive-url=https://web.archive.org/web/20100415100850/http://www.panthera.org/documents/HunterAfGeo2004CarnivoresInCrisisPart1.pdf |archive-date=April 15, 2010}}</ref>

Although these regulations seem to provide a strong legal framework for controlling the commerce involving big cats, international organizations such as the [[World Wildlife Fund]] (WWF) have encouraged the U.S. to further strengthen these laws.
