Unnatural mix-and-match felines have no conservation purpose, experts say.

You may have heard of a liger—the lion-tiger hybrid is, after all, Napoleon Dynamite's
favorite animal—but now a Russian zoo has released photos of a
so-called "liliger" named Kiara, the offspring of a liger mother and a
lion father. (See liger pictures.)
The
cub, born last week at Novosibirsk Zoo, may be the only liliger in
existence. But charming as the cuddly cub appears, ligers, liligers, and
other mix-and-match felines raise serious concerns for advocates of big-cat conservation.
Ligers are the result of a male lion mating with a female tiger. Craig Packer,
director of the Lion Research Center at the University of Minnesota,
said he hasn't heard of a liliger before but is "not surprised" that it
exists.
All ligers are born in captivity, Packer
said, because this animal simply does not exist in the natural world.
Not only are wild lion and tiger populations separated by geography,
there are certain behavior mechanisms in place that would prevent the
two species from mating.
"If a tiger tried to
mate with a female lion it would be chased away by the other lions
pretty fast, and vice versa," said Packer, who is also a National Geographic Society/Waitt Foundation grantee.
Liligers "Irrevelant" for Conserving Big Cats
That
can change in captivity. Given no other options, lions and tigers may
breed. "Lions and tigers are separated by about seven million years of
evolution," Packer said, "but they are still closely enough related that
they can hybridize."
In the wild, an animal
like Kiara would "probably be very mixed up," Packer speculated. "Lions
are genetically predisposed to be very sociable and cooperative. Tigers
are genetically predisposed to be very ornery and solitary." (See big-cat pictures.)
While zoos in some countries do cross-breed cats (probably for the publicity value), U.S. zoos typically do not. The Association of Zoos and Aquariums (AZA),
the accrediting body for zoos in North America, does not approve of
ligers, said spokesperson Steve Feldman, and no AZA zoos breed them.
Modern zoological institutions, he said, instead focus on
wildlife-conservation programs.
Packer, who has devoted his career to studying lions, can't imagine why zoos would breed liligers and other such hybrids.
"In terms of conservation," he said, "it's so far away from anything, it's kind of pointless to even say it's irrelevant."
