How cheetahs stay fit and healthy
Cheetahs are categorized as vulnerable species, partly because they have been considered to be prone to diseases due to their supposed weak immune system. However, they are hardly ever sick in the wild. A research team has recently discovered that cheetahs have developed a very efficient innate “first line of defense” immunity to compensate potential deficiencies in other components of their immune system.

Closely related yet so different
Southeast Asia is home to numerous felids, including the Asian golden cat and the bay cat. The two cat species are closely related sister species which split from each other 3.16 million years ago. Yet, their more recent history was quite different. Scientists could now show that, after a massive volcanic eruption about 73,000 years ago, the Asian golden cat survived only in Indochina, from where it expanded its range in dramatic fashion during the peak of the last Ice Age. The cooler and drier climates at the time pushed its sister species, the bay cat, however, into rainforest refuges on Borneo.

Rare combination of genetic changes increases the virulence of canine distemper virus
The long-running debate about why just one of several canine distemper virus (CDV) outbreaks in the Serengeti in Tanzania during the past 25 years was fatal for lions and spotted hyenas has been resolved. An international team of scientists conducted genetic analyses of CDV strains obtained from a range of carnivores between 1993 and 2012 and discovered that lethal CDV infections in lions and hyenas during the 1993/1994 epidemic was caused by a rare and genetically distinct CDV strain with three rare mutations not present in any other Serengeti strain isolated from domestic dogs or wild canids. Two of these rare mutations were found to increase the ability of CDV to invade lion cells.

Toxoplasma's balancing act explained
The parasite Toxoplasma gondii is a silent success. It infects up to 95% of people in many regions of the world, and most of them never know it, due to the parasite’s artful manipulation of its host’s immune response. Toxoplasma keeps the immune response low enough so that it can thrive, but high enough so that its human hosts generally live healthy lives and can incubate parasites. Scientists have uncovered one of the ways it maintains this balance.

Trophy hunting of lions can conserve the species, report suggests
Trophy hunters can play an important role in lion conservation, researchers have shown. These findings may surprise the public, but most lion conservationists think trophy hunting could play a key role in conserving this species because lions need large areas to thrive, and managing this land is expensive. The new work shows land under long-term management for trophy hunting can help fill this shortfall.

Zolushka sighting: The tiger Cinderella story continues
Brought into captivity as a nearly starved, 3-month old cub, the tigress that became known as Zolushka (Russian for "Cinderella") flourished in a rehabilitation center designed to prepare her for life back in the wild. Without a mother (probably lost to poachers) Zolushka learned how to kill natural wild prey presented to her in the rehabilitation center, where she was kept far from people to preserve her innate fear of humans. New photographs just released from Bastak Reserve in the Russian Far East confirm that a feline Cinderella story continues to unfold.

Male and female cats respond differently to distressed kittens
Female domestic cats adjust their response to kitten calls depending on how urgent they sound, according to a study. Independent of their own experience of raising kittens, female cats distinguish between kitten calls that convey different levels of urgency and react accordingly, researchers have found. Male cats do not adjust their response in similar ways.
