Why do cats do that?

They're cute, they're lovable,

and judging by the 26 billions views
of over 2 million YouTube videos

of them pouncing,

bouncing,

climbing,

cramming,

stalking,

clawing,

chattering,

and purring,

one thing is certain:

cats are very entertaining.

These somewhat strange feline behaviors,

both amusing and baffling,

leave many of us asking,
"Why do cats do that?"

Throughout time, cats were simultaneously
solitary predators of smaller animals

and prey for larger carnivores.

As both predator and prey,

survival of their species depended
on crucial instinctual behaviors

which we still observe in wild 
and domestic cats today.

While the feline actions of your house cat
Grizmo might seem perplexing,

in the wild, these same behaviors,

naturally bred into cats 
for millions of years,

would make Grizmo a super cat.

Enabled by their unique muscular structure
and keen balancing abilities,

cats climbed to high vantage points
to survey their territory

and spot prey in the wild.

Grizmo doesn't need these particular
skills to find and hunt down dinner

in her food bowl today,

but instinctually, viewing the living room
from the top of the bookcase

is exactly what she has evolved to do.

As wild predators, cats are opportunistic
and hunt whenever prey is available.

Since most cat prey are small,

cats in the wild needed to eat 
many times each day,

and use a stalk, pounce, kill, eat
strategy to stay fed.

This is why Grismo prefers to chase
and pounce on little toys

and eat small meals over the course
of the day and night.

Also, small prey tend to hide in tiny
spaces in their natural environments,

so one explanation for Grizmo's propensity
to reach into containers and openings

is that she is compelled by 
the same curiosity

that helped ensure the continuation of
her species for millions of years before.

In the wild, cats needed sharp claws
for climbing, hunting, and self-defense.

Sharpening their claws on nearby surfaces
kept them conditioned and ready,

helped stretch their back and leg muscles,

and relieve some stress, too.

So, it's not that Grizmo hates your couch,

chair,

ottoman,

pillows,

curtains,

and everything else 
you put in her environment.

She's ripping these things to shreds
and keeping her claws in tip-top shape

because this is exactly what her ancestors
did in order to survive.

As animals that were preyed upon,

cats evolved to not get caught,

and in the wild, the cats that were 
the best at avoiding predators thrived.

So at your house today,

Grizmo is an expert 
at squeezing into small spaces

and seeking out and hiding
in unconventional spots.

It also explains why she prefers
a clean and odor-free litter box.

That's less likely to give away 
her location to any predators

that may be sniffing around nearby.

Considering everything 
we do know about cats,

it seems that one of their most 
predominate behaviors

is still one of the most mysterious.

Cats may purr for any number of reasons,

such as happiness,

stress,

and hunger.

But curiously, 
the frequency of their purrs,

between 25 and 150 hertz,

is within a range that can promote
tissue regeneration.

So while her purring makes Grizmo
an excellent nap companion,

it is also possible that her purr
is healing her muscles and bones,

and maybe even yours, too.

They developed through time

as both solitary predators 
that hunted and killed to eat,

and stealthy prey that hid
and escaped to survive.

So cats today retain many 
of the same instincts

that allowed them to thrive in the wild
for millions of years.

This explains some of their seemingly
strange behaviors.

To them, our homes are their jungles.

But if this is the case, 
in our own cat's eyes,

who are we?

Big, dumb, hairless cats competing with
them for resources?

Terribly stupid predators they're able
to outsmart everyday?

Or maybe they think we're the prey.
