Amazing Cats: The Sunda Clouded Leopard

This singular species of wildcat exists only on two islands and has evolved to live a semi-arboreal existence deep in the jungle.

While tigers, lions and domestic cats are the stars of the felid world and command the lion’s share (pun intended) of the attention, even from cat lovers, there are obscure species living in far-off locations where they’re rarely glimpsed by human eyes.

There’s the fishing cat, the black-footed cat and the sand cat, and then there are species that are obscure even among the obscure. The Sunda clouded leopard fits into that category, inasmuch as the unique felid can fit into any category.

Like orangutans, the Sunda clouded leopard can be found in only two places in the world: the Indonesian islands of Borneo and Sumatra. They’re faced with the same existential threat that has pushed orangutans dangerously close to extinction, which is the relentless destruction of old-growth jungle to clear land for more palm oil plantations.

Palm oil is coveted by multinational corporations in the food and cosmetics businesses, and it’s in everything from chocolate and instant noodles to lipstick and margarine, according to the World Wildlife Fund.

The problem with razing old growth jungle and forest is that it doesn’t just grow back. They’re extremely delicate ecosystems that have arrived at a natural balance over thousands of years, with every species of animal and plant contributing something vital to the vibrant tapestry of life the jungles host and support. You can’t just plant trees and usher animals to a new home. It would take hundreds of years for those new jungles to even superficially resemble the lifegiving old growth jungle.

There are heartbreaking images of shocked orangutans sitting in the ruins of their former homes, with nothing but the stumps of trees and dozer-trodden vegetation as far as the eye can see.

Those are the lucky ones. The loggers who work for massive multinational corporations aren’t bound by rules or ethics, and they won’t wait for animals to clear out before they destroy.  They often shoot orangutans on sight regardless of whether the animals are carrying young.

That’s the primary reason why Borneo and Sumatra are now home to entire academies for orangutan orphans, who spend at least eight years learning how to fend for themselves with the help of specialists who teach lessons that would normally be taught by the orphan orangutans’ mothers. They include the very basics, like how to move and climb through the jungle, as well as crucial information such as which berries to avoid while foraging.

While there’s no “academy” for clouded leopards and the felids are more adept at avoiding human wrecking crews, they’ve suffered the same fate as orangutans when it comes to dwindling jungles.

This is the situation Sunda clouded leopards find themselves in, so when a trail camera recently captured footage of a mother and her two cubs, conservationists were thrilled.

The footage comes from camera traps belonging to the Orangutan Foundation, and it’s the first time anyone’s managed to obtain video of the Bornean clouded leopards with cubs in tow. The brief video shows the little family bounding through the jungle. They quickly move past the camera, but not before one of the cubs stops to look right at it with typical kitten curiosity.

Sunda clouded leopards are extraordinary cats. Size-wise, they are firmly in the “medium size wildcat” category, with males weighing about 50 pounds. Despite that, they are members of pantherinae, the genus of big cats, having diverged from a common ancestor shared with tigers, leopards, lions and jaguars.

As further proof of their in-between status, Sunda clouded leopards can neither purr nor roar. Typically, each species of felid can do one or the other. Even the species’ scientific nomenclature, neofelis nebulosa, references its intermediate status. (If you encounter alternate taxonomy for them, it’s because the clouded leopards of Borneo and Sumatra are considered distinct subspecies.)

“Due to a different bone structure in their neck, the clouded leopard cannot roar like the larger cats, but also cannot purr because it lacks the fully ossified hyoid bone that allows small cats this ability,” the Smithsonian National Zoo’s keepers explain.

Sunda clouded leopards have several unique adaptations that allow them to thrive in arboreal environments. Their massive tails act as crucial counterweights, allowing them to traverse branches high above the ground without falling. Their paws and paw pads are specialized for gripping tree branches, and their ankles can articulate in ways other felid ankles cannot, allowing the jungle-dwelling wildcats to descend from trees head-first.

Domestic cats infamously lack this adaptation, which is why firefighters are also part-time cat rescuers, coaxing the terrified little ones down from trees, utility poles and rooftops.

The clouded leopards of Borneo and Sumatra are also undeniably cute. People have noticed, which is why one of Google’s auto-complete suggestions for Sunda clouded leopard suggests the word “pet” as an addition. It’s okay to fantasize about having a clouded leopard buddy, but in addition to the fact that they are endangered, they’re also wild animals.

Consider the fact that across the estimated 200,000 years of our species’ existence, homo sapiens have domesticated precisely one felid species, and even that’s not entirely accurate. Felis catus played just as much of a role — and arguably more — than humans did in their own domestication. As predators and obligate carnivores, they are unique among domestic animals, and it took and equally unique set of circumstances to bring cat and man together.

Instead of lamenting the fact that Sunda clouded leopards can’t be pets, we can admire them in the best way possible, from a distance, while helping ensure the survival of this extraordinary, distinctive species by donating to groups like Panthera, the WWF and Global Conservation.

Tiny Sand Cats Have The Largest Ranges Of All Felines, Study Says

The little-known, Lilliputian species of feline thrives in some of the harshest environments on Earth, proving cat species are capable of remarkable adaptations to their surroundings.

There’s a lot we don’t know about felis margarita, so much so that kittens of the elusive and stealthy species weren’t photographed in the wild until 2017.

Now a study has unveiled a surprising fact about sand cats: despite being tiny in stature, they occupy huge ranges that can rival the size of territories claimed by big cats like tigers and jaguars. One cat claimed 1,758 square kilometers — about 1,093 square miles — for himself according to Gregory Breton, the study’s author, who said the cat’s behavior showed sand cat ranges are “considerably larger than previously estimated.”

That individual maintained his impressive range for more than six months before moving on. His behavior and the movement of 21 others tracked via radio collars suggests the species could be semi-nomadic, moving or adjusting their ranges as they look for prey and water in some of the hottest, most arid environments on the planet.

“If true, this type of movement in response to rainfall is previously unrecorded among wild cat species,” wrote Breton, who is managing director of the cat conservation group Panthera in France.

In addition to following sources of water, the cats may maintain such large ranges because prey are more spread out compared to biomes like jungles, forests and wetlands where other species of cats make their homes.

Impressive ranges weren’t the only surprise the tiny cats had for researchers. Breton and his colleagues managed to catch and examine more than 40 sand cats before releasing them back into the wild and noted they were all healthy, with few scars, no fresh wounds and no broken teeth.

The lack of wounds “means that it is likely that sand cats exhibit little territoriality and tolerate each other across their ranges,” Breton wrote  “This beloved cat may indeed share habitat with others of its species — maybe their perception does match their nature, at least towards other sand cats.”

Sand cats can be found in the Algerian Sahara, the deserts of the Arabian Peninsula and countries like Chad, Niger and Morocco. The Panthera team tracked the Lilliputian felines in the latter country, traversing the desert and arid landscapes of southwestern Morocco where temperatures peaked at 122 degrees Fahrenheit (50 degrees Celsius) during the day.

Sand cats have what Breton describes as “whimsical faces,” sporting wide, swept ears to go along with the general horizontal appearance of their heads.

They have golden, classic tabby markings and sand-colored fur with well-defined dark rings on their limbs, allowing them to expertly blend into their surroundings. Sand cat camouflage is so effective and the species is so quiet that one of the best ways to find them is at night, using search lights to pick out their reflective inner eyelids amid the desert landscape.

They’re also considerably smaller than house cats, weighing up to 7.5 pounds.

Breton said his team’s research is critical for estimates of sand cat population, which in turn will help authorities determine the conservation status of the elusive feline.
