♪♪ NARRATOR: From the iconic big cats that enthrall us... [ Snarls ] ♪♪ To the little-known small cats that are just coming into the light... this is a remarkable family of predators.

♪♪ They are super athletes... Super hunters... Possessing super senses.

Now, groundbreaking filming techniques and a surge in scientific research are revealing new facets of this amazing super family.

♪♪ [ Theme music playing ] ♪♪ ♪♪ ♪♪ NARRATOR: Dawn in the Namibian desert.

♪♪ ♪♪ Cheetahs are one of the few cats to form long-term coalitions with their siblings.

♪♪ For males, the relationship might be life-long.

They'll do everything together... ♪♪ even hunt.

♪♪ ♪♪ Few cats can resist a chase... but none give chase quite like a cheetah.

♪♪ ♪♪ ♪♪ The latest science tells us cheetahs rarely reach their record top speed.

So, if cheetahs don't rely simply on being fast, how do they catch their prey?

It's a question that requires a new perspective.

[ Cheetah growls ] This high-speed buggy is mounted with a stabilized slow-motion camera to give us the prey's-eye view.

♪♪ ♪♪ ♪♪ Their sprinting prowess is unrivaled.

♪♪ ♪♪ But this new approach reveals that there's far more to cheetahs than just straight line speed.

Cheetahs must not only keep up with their targets, but react to every twist and turn.

♪♪ Their blunt claws are running cleats that provide traction.

♪♪ Even at 50 miles an hour, the grip allows them to change direction, instantly... And their long tails whip around to keep them upright.

♪♪ ♪♪ They can also brake hard.

♪♪ Strong bones are shock absorbers, dissipating forces that could break a human leg.

♪♪ Cheetahs are more than just sprinters outrunning prey on open plains...

They're agile... and maneuverable.

They're elite athletes.

♪♪ ♪♪ And where that really counts is here, in woodland.

♪♪ This is an obstacle course where the prey's best chance is to weave and turn to escape.

♪♪ So a cheetah can rarely hit top speed.

♪♪ ♪♪ This chase is not a race...

It's a dance.

♪♪ The prey leads... ♪♪ and the predator must follow.

♪♪ ♪♪ ♪♪ ♪♪ Cheetahs are the fastest animals on land, incredible sprinters, but so much more.

♪♪ Even now, iconic cats like cheetahs can still surprise us.

♪♪ And there are other members of this extraordinary family about which we know even less.

♪♪ Hiding in this Sri Lankan jungle is a cat so rare, few have ever seen it.

♪♪ Exploring the world beyond his den for the first time is a miniature predator.

♪♪ ♪♪ The smallest feline in the world... A rusty spotted cat.

♪♪ [ Sniffing ] He may look like a kitten -- [ Mews ] He'd still fit in the palm of your hand.

But this little male is nearly full grown.

He'll soon be setting off on a solitary life, fending entirely for himself.

What he lacks in size, he makes up for in daring.

♪♪ ♪♪ Young cats are born curious -- it's how they learn about their world... ♪♪ Even if it can get them into trouble.

[ Branch creeks, cat mews ] Right away, he puts his super senses through their paces.

♪♪ ♪♪ His eyes are six times more powerful than our own and sensitive to the slightest movement.

♪♪ His whiskers, rooted in a bed of nerves, detect the faintest touch or the gentlest breath of wind.

[ Animal screeching ] His hearing is better than ours too... tuned to sounds that are completely imperceptible to the human ear.

[ Animals calling ] And his sense of smell is capable of distinguishing between a billion different odors.

[ Sniffing ] ♪♪ This little cat is alert to every change in his surroundings... ♪♪ But now it's time to learn which sounds... or sights... signal danger.

[ Mews ] ♪♪ ♪♪ Every step of today's adventure has been stored away in his memory.

He's building a 3-D map of the jungle in his head... ♪♪ so he can find his way home in a flash.

♪♪ All cats, from the smallest to the biggest, share extraordinary skills and abilities that have allowed them to conquer all four corners of the globe.

♪♪ Siberian tigers prowl frozen forests.

They are 200 times bigger than a rusty spotted cat... but just as elusive.

♪♪ In Brazil's Pantanal, the world's largest wetland, jaguars are on the hunt for monsters.

♪♪ ♪♪ For their size, they have the strongest bite of any cat... even making short work of huge caiman crocodiles.

♪♪ The jungle canopy of South and Central America is the realm of the tree climbing margay.

♪♪ They can judge distances perfectly... A critical skill if you're to clear a gap of 12 feet with a single leap, high above the forest floor.

♪♪ And when it's time to descend, their ankles rotate 180 degrees so they can walk vertically down.

♪♪ Whether it's hunting in the swamps of Asia... ♪♪ or patrolling the oldest desert in Africa... ♪♪ cats thrive everywhere.

♪♪ ♪♪ They've even conquered the highest mountains on Earth: the Himalayas.

♪♪ It's a place where food is scarce... ♪♪ So, to survive, you need a huge territory.

♪♪ ♪♪ This vast wilderness of sheer cliffs and bare rock is home to the snow leopard... the world's highest, and just maybe most lonesome cat.

♪♪ This aging male is searching... ♪♪ but not for food...

He's looking for a mate.

♪♪ ♪♪ The task would be nearly impossible if it wasn't for a cat's unique ability for long distance romance.

♪♪ His long-lasting and pungent spray carries his dating profile.

"Male, single, would like to meet."

♪♪ Both males and females spray, posting their romantic status to any and every one that passes by.

♪♪ So he diligently patrols these paths every day in the hope that a potential mate has passed through.

♪♪ At his most eager, he'll scent mark 20 times an hour.

♪♪ ♪♪ It may take a week or more to cover his entire territory, but his search must go on, day after day, in spite of the Himalayan weather.

♪♪ ♪♪ ♪♪ ♪♪ He checks for scent... then leaves his own.

♪♪ ♪♪ Here, he discovers a female has left her mark.

♪♪ Rubbing his own scent over hers, he declares his interest.

♪♪ ♪♪ ♪♪ This male might just have one last chance to mate.

♪♪ ♪♪ Could this be it?

♪♪ [ Distant yelping ] On the wind, the call of a distant female.

[ Distant yelping ] ♪♪ [ Distant yelping ] ♪♪ [ Distant yelping ] ♪♪ ♪♪ [ Nearby yelping ] Just maybe this male's search is over.

[ Yelping ] ♪♪ ♪♪ [ Continues yelping ] ♪♪ [ Yelping echoes ] For male cats, life is a lonely existence... ♪♪ But for females, it's very different.

♪♪ ♪♪ ♪♪ This is Honey... ♪♪ a female African leopard -- and a mother.

A radio collar is giving researchers an insight into the life of the most elusive of Africa's big cats.

♪♪ ♪♪ [ Roars ] ♪♪ Leopards thrive in more environments than any other cat, but that doesn't mean their lives are easy.

At 10 years old, Honey has outlived her brothers and sisters.

Somehow, she's survived a broken leg, and now, during the worst drought in decades, she's hunting for two.

[ Growls ] For mother cats, childcare is a balancing act between protection and provision.

♪♪ If they're to hunt successfully, a leopard must do so alone.

So she's left her young cub behind.

♪♪ A tail twitch -- Honey is on to something.

♪♪ ♪♪ The drought has withered all vegetation, so there's little cover.

She needs to get close -- within 12 feet -- to stand any chance of success... ♪♪ And anything could give the game away.

[ Birds clucking ] ♪♪ [ Clucking rapidly ] ♪♪ [ Clucking rapidly ] [ Snarls ] ♪♪ Foiled by Africa's most annoying alarm call.

♪♪ [ Grunting ] ♪♪ Her calls are unanswered.

♪♪ Half of all leopard cubs don't survive their first year.

[ Grunting ] A cub's best chance is to stay hidden until she's sure it's safe.

[ Honey grunting ] ♪♪ Honey's youngster already has a leopard's knack for stealth.

She can even give her mother a surprise.

♪♪ ♪♪ ♪♪ For the last six months, she's grown strong on milk.

But now she's developing a cat's appetite for meat.

♪♪ ♪♪ ♪♪ A mother leopard always has a backup plan.

Honey has stashed a kill safely out of the reach of thieves.

♪♪ ♪♪ ♪♪ For her cub, this is an important lesson -- and the first of many.

Across the cat family, kittens and cubs have a long infancy.

It takes time to learn the skills needed to hunt for themselves.

♪♪ ♪♪ Often brothers and sisters are on hand for training.

♪♪ ♪♪ ♪♪ Play is the key to honing coordination... Building strength... And agility.

♪♪ The bond between them might endure for years, probably the closest relationship they'll ever have with another cat... ♪♪ But there is one life skill which they must master alone... ♪♪ The surprise attack.

♪♪ ♪♪ If he can avoid a chase, he will.
