Liger (lion × tigress)|
|Ti-liger, a backcross hybrid produced by mating a male tiger with a ligress (lion × tigress)|
A hybrid between a lion and a tigress is known as a liger (the reciprocal cross, tiger × lioness, produces what is known as a tigon). This cross has occurred many times in captivity.
Ligers, especially males, can be much larger than either lions or tigers, sometimes as large as both of their parents together, up to 1,250 lbs (470 kg). The largest cats in the world, they stand about 12 feet (3.66m) tall on their hindlegs. Ligers are much larger, and far more common than tigons because breeders prefer their larger size, which affords a more sensational exhibit (tigons are often smaller than either a lion or a tiger, usually weighing no more than 350lbs/160kg). Also, P. tigris males cross less willingly than P. leo males. The female hybrids are able to produce offspring in backcrosses with both lion and tiger males.
The mane of a male liger is smaller than that of a pure lion (tigons may have no mane at all). Their stripes are brown instead of black, on a background of intermediate tone. They can make the sounds of both a lion and a tiger (in general, it is typical for the offspring produced by any given type of hybrid cross to produce vocalizations that are a mixture of the vocalizations of the two parents participating in that cross). Like tigers, ligers lack a lion’s aversion to water.
Courtney (1980, p. 22) says there have been rare reports of natural hybrids. In the past, when tigers and lions were far more common than today and frequently came into potential breeding contact, natural hybridization may well have been frequent.vToday, these cats co-occur only in India’s Gir Forest, but their ranges formerly overlapped widely in Asia.

This cross has long been known and has been bred in zoos and for circuses the world over. It was reported as early as 1788 (Trewman’s Exeter Flying-Post, July 31), and in India there is a long tradition of breeding these hybrids. An Indian princess gave one to Queen Victoria upon her accession in 1837. Nevertheless, the Indian government recently (1985) passed legislation forbidding their production.
Noting that the cave lion, a massive cat (400-500kg) that existed during the Pleistocene in Eurasia, has been classified both as a type of lion and as a type of tiger and that it has osteological traits that link it to both, Rousseau suggests it may have been a natural hybrid of this type, and notes that the skeletons of cave lions, particularly the mandibles, are similar to those of known hybrids. The cave lion has been treated as a species (Panthera spelea).
The following is a list of some of the cat crosses discussed on this site. Some of these crosses are much better documented than others (as indicated by the reliability arrow). Indeed, some might seem completely impossible. But all have been reported at least once. The links below are to separate articles. Additional crosses, not listed here, are covered on the cat hybrids page.
