TI-TIGON, TI-LIGER (TIG-LIGER), LI-TIGON, LI-LIGER

Female tigons and ligers are often fertile and can mate with a lion, tiger or in theory with another species such as leopard or jaguar.

According to "Wild Cats Of The World" (1975) by Guggisberg, ligers and tigons were long thought to be sterile: "In 1943, however, a fifteen year old hybrid between a lion and an 'Island' tiger was successfully mated with a lion at the Munich Hellabrunn Zoo. The female cub, even though very delicate, was raised to adulthood." Prior to this all lion-tiger hybrids were believed to be sterile (even though other hybrid females such as jagulep females were already known to be fertile). 1943 seems to be the first recorded instance of a second generation hybrid of tiger and lion. This female tigon produced nine cubs in five litters between 1948 and 1950.

H Hemmer (1966) described the offspring of a female liger and a male lion (li-liger) as being smaller than a normal lioness. Its tiger markings were barely recognisable in summer, but were somewhat plainer in the winter coat. The progeny of female ligers mated to lions have also been described as resembling young lions.

Tigers and ligers have been mated together to produce ti-ligers (tig-ligers). Tigers and tigons have been mated to produce ti-tigons (below). Ti-ligers and ti-tigons are more tigerlike (75% tiger). Ti-tigons resemble golden tigers but with less contrast in their markings.

During the late 1970s/early 1980s, the Shambala Preserve had both a tigon and a ti-tigon. The full illustrated story of Noelle the tigon and Nathaniel, her ti-tigon son, is detailed in "The Cats of Shambala" by Tippi Hedren (also an article by V Junger, People 11:90-1 Jan. 22, 1979.). On Christmas morning 1978, handler Brad Darrington found a 1 lb striped female cub hidden behind the den box in Nikita's compound. Nikita was the preserve's 600 lb tiger who ruled a pride of 9 lionesses. The cub was believed to have be born to Debbie, a lioness that had arrived from LA Animal Control as an orphan in 1974. None of the lionesses was thought to have been pregnant, though they did sometimes give birth surreptitiously. Debbie rejected the cub. The was named Noelle and was hand-reared. At 5 days old, Noelle began making the nasal, puffing "ff-fuff" sounds of the tiger as well as the happy "aa-oow" of a lion cub. While tiger cubs dislike being held or cuddled, Noelle had the cuddly nature of a lion cub. Her nose was tiger-like rather than blunt like a lion. At about 2 weeks old, Noelle was diagnosed with septic arthritis which caused her to limp. At the time of Noelle's birth, Hedren knew of only 3 other tigons in the US.

Being such a rarity, Noelle was widely photographed and her image appeared in magazines and articles around the world. At the age of 4 years, she was a little larger than the average lioness, being taller and longer-legged. Standing on her hind legs she measured 13 ft from tail tip to nose tip. Her stripes were brown, rather than black, on an orange background colour with a white belly. She had mottled spots on the top of her head. Her vocalisations were lioness-like rather than tigress-like and she had the sociable nature of the lion combined with the playfulness and love of water of the tiger. She also inherited an excellent jumping ability, easily making 10 ft vertical leaps.

Noelle  was housed with 3 other tigresses and a 5 year old Amur (Siberian) tiger called Anton. Although the other lionesses and tigresses at the preserve were put on the contraceptive pill, Noelle was wrongly assumed to be sterile because she was a hybrid. She therefore came on heat regularly and mated with Anton from spring 1982 onwards. When Noelle displayed signs of pregnancy, it was assumed to be a false pregnancy (hormonal/psychological), however, on September 16th, 1983, she gave birth to a single small male cub. Noelle and the cub had to be separated from the other females who were attempting to kidnap the cub, wounding it in the process. The cub was named Nathaniel, this being derived from Tippi's birth name of Nathalie. Nathaniel was possibly the only ti-tigon in the world at the time.

Ti-liger

Ligress Julie and her cub (either a ti-liger or li-liger - paternity was not stated).

Being 75% tiger, Nathaniel was more tiger-like than his mother. He had clearly defined darker stripes and facial markings and his coat that was unusually long and thick. Nathaniel "spoke" tiger rather than a mix of lion of and tiger. Instinctively Noelle "spoke" tiger to her cub. When Nathaniel was 6 weeks old, it became necessary to remove him from Noelle in order to imprint him on humans since Shambala's big cats were trained for films. From then on he was hand-reared although after several months, he was reintroduced to Noelle who began to teach him big cat manners. Being only 25% lion, Nathaniel did not grow a mane although he did achieve an impressive size. He died age 8 or 9 years old due to cancer. His tigon mother, Noelle, also developed cancer and died not long after. It is possible that the mix of genes contributed to the illness.

On April 24, 1984, The Times reported the birth of a "tigron" (ti-liger or li-liger) at the tiger park in Thoiry near Paris. The park was owned by Vicomte Paul de la Panouse who allowed lions and tigers to roam freely together; so freely they interbred. The Vicomte got into the liger business because of the habit of lionesses and tigresses of killing or neglecting their cubs. On April 17, a female "ligron" (liger) called Julie gave birth to the cub. Julie was one of 4 liger offspring from a lion called "Bichon" and 2 tigresses called "Les Mechantes" (the naughty/nasty ones). The ligers were hand-reared. The father of Julie's cub is believed to be either her father Bichon (resulting in a li-liger) or her half-brother, Patchwork (ligron/liger). It was reported that in 1984 2 "ligrons" (ligers) mated and produced offspring, thus disproving that hybrids were sterile (The Gazette, Montreal, Quebec, May 14, 1988. p I3 ); but the sire of the 2nd generation was probably Julie's own sire, a lion.

More recently, a roadside zoo conducting a behavioural research programme in the USA bred a female ti-liger called Lady Kali; at 2 years old she weighed 400 lbs.

Lions and ligers have been mated together to produce li-ligers. Lions and tigons have been mated to produce li-tigons. These hybrids are more lion-like (75% lion). In 2012 and in May 2013, a female liger called Zita at Novosibirsk, Russia produced 2 litters of li-liger cubs sired by an African lion called Sam. The second litter comprised three female cubs. Their baby coats are heavily marked with evenly spaced vertically elongated black rosettes, and black spots on the face and limbs and a spotted and ringed tail. The alignment of the darker markings are due to their tiger heritage.

Male hybrids are rarely, if ever, fertile even if they do display sexual behaviour. To date, all male ligers, tigons, ti-tigons and li-tigons investigated have apparently proven sterile. There are no authenticated liger x tigon, liger x liger or tigon x tigon hybrids. Theoretical offspring could be lion-like, tiger-like, liger-like or tigon-like, depending on what combination of genes they inherited. It is more likely that anecdotally reported offspring from supposed hybrid-to-hybrid matings actually resulted from unobserved additional matings of a hybrid female with a pure-bred lion or tiger.

Some visitors to this site have asked what would happen if a tigon or liger was mated back to a lion. See Backcrossing for information.

 

LIGER & TIGON COLOURS

White tigers have been crossed with lions to produce white ligers. Everland Zoo (Yongin Farm Zoo) in Seoul, Korea has produced white ligers, possibly from white tigers and leucistic lionesses. Big Cat Rescue's white tiger apparently co-habitates with a lion, as it was the intention of the original owner to breed white ligers. Golden tigers have been crossed with lions to produce golden ligers. In theory white tigers could be crossed with white lions to produce truly white ligers. White tigons or golden tigons are also possible, but because tigons do not attain the huge size of the liger there is far less interest in breeding them.

A black liger would be an impressive creature, but to breed one would require both a melanistic tiger and a melanistic lion because the gene for black must be inherited from both parents and to guarantee a black liger requires both parents to be black. Very few true melanistic tigers have ever been recorded. Most "black tigers" are due to pseudo-melanism i.e. the markings are so heavy that the tawny background colour is almost hidden. No reports of black lions have ever been substantiated.

In felines, "blue" means a slate-grey colour. Genetically, it is a form of melanism where the colour has been diluted from black to grey. To breed a blue liger would require a blue (i.e.grey) tiger and a black lion (or black tiger and blue lion. Or blue tiger and blue lion). Blue tigers have been recorded in China, but none have occurred in captivity. To date, no grey lions have been recorded.
