Why do cats act so weird? - Tony Buffington

  • 0:07 - 0:09
    Why do cats do that?
  • 0:13 - 0:14
    They're cute, they're lovable,
  • 0:14 - 0:20
    and judging by the 26 billions views
    of over 2 million YouTube videos
  • 0:20 - 0:21
    of them pouncing,
  • 0:21 - 0:22
    bouncing,
  • 0:22 - 0:23
    climbing,
  • 0:23 - 0:24
    cramming,
  • 0:24 - 0:25
    stalking,
  • 0:25 - 0:25
    clawing,
  • 0:25 - 0:26
    chattering,
  • 0:26 - 0:27
    and purring,
  • 0:27 - 0:29
    one thing is certain:
  • 0:29 - 0:32
    cats are very entertaining.
  • 0:32 - 0:34
    These somewhat strange feline behaviors,
  • 0:34 - 0:36
    both amusing and baffling,
  • 0:36 - 0:41
    leave many of us asking,
    "Why do cats do that?"
  • 0:41 - 0:46
    Throughout time, cats were simultaneously
    solitary predators of smaller animals
  • 0:46 - 0:49
    and prey for larger carnivores.
  • 0:49 - 0:51
    As both predator and prey,
  • 0:51 - 0:56
    survival of their species depended
    on crucial instinctual behaviors
  • 0:56 - 1:01
    which we still observe in wild
    and domestic cats today.
  • 1:01 - 1:05
    While the feline actions of your house cat
    Grizmo might seem perplexing,
  • 1:05 - 1:07
    in the wild, these same behaviors,
  • 1:07 - 1:10
    naturally bred into cats
    for millions of years,
  • 1:10 - 1:13
    would make Grizmo a super cat.
  • 1:13 - 1:18
    Enabled by their unique muscular structure
    and keen balancing abilities,
  • 1:18 - 1:22
    cats climbed to high vantage points
    to survey their territory
  • 1:22 - 1:25
    and spot prey in the wild.
  • 1:25 - 1:29
    Grizmo doesn't need these particular
    skills to find and hunt down dinner
  • 1:29 - 1:31
    in her food bowl today,
  • 1:31 - 1:34
    but instinctually, viewing the living room
    from the top of the bookcase
  • 1:34 - 1:38
    is exactly what she has evolved to do.
  • 1:38 - 1:44
    As wild predators, cats are opportunistic
    and hunt whenever prey is available.
  • 1:44 - 1:46
    Since most cat prey are small,
  • 1:46 - 1:50
    cats in the wild needed to eat
    many times each day,
  • 1:50 - 1:55
    and use a stalk, pounce, kill, eat
    strategy to stay fed.
  • 1:55 - 1:59
    This is why Grizmo prefers to chase
    and pounce on little toys
  • 1:59 - 2:03
    and eat small meals over the course
    of the day and night.
  • 2:03 - 2:08
    Also, small prey tend to hide in tiny
    spaces in their natural environments,
  • 2:08 - 2:13
    so one explanation for Grizmo's propensity
    to reach into containers and openings
  • 2:13 - 2:15
    is that she is compelled by
    the same curiosity
  • 2:15 - 2:24
    that helped ensure the continuation of
    her species for millions of years before.
  • 2:24 - 2:30
    In the wild, cats needed sharp claws
    for climbing, hunting, and self-defense.
  • 2:30 - 2:35
    Sharpening their claws on nearby surfaces
    kept them conditioned and ready,
  • 2:35 - 2:37
    helped stretch their back and leg muscles,
  • 2:37 - 2:39
    and relieve some stress, too.
  • 2:39 - 2:41
    So, it's not that Grizmo hates your couch,
  • 2:41 - 2:42
    chair,
  • 2:42 - 2:43
    ottoman,
  • 2:43 - 2:44
    pillows,
  • 2:44 - 2:45
    curtains,
  • 2:45 - 2:47
    and everything else
    you put in her environment.
  • 2:47 - 2:52
    She's ripping these things to shreds
    and keeping her claws in tip-top shape
  • 2:52 - 2:58
    because this is exactly what her ancestors
    did in order to survive.
  • 2:58 - 3:00
    As animals that were preyed upon,
  • 3:00 - 3:02
    cats evolved to not get caught,
  • 3:02 - 3:06
    and in the wild, the cats that were
    the best at avoiding predators thrived.
  • 3:06 - 3:08
    So at your house today,
  • 3:08 - 3:11
    Grizmo is an expert
    at squeezing into small spaces
  • 3:11 - 3:16
    and seeking out and hiding
    in unconventional spots.
  • 3:16 - 3:20
    It also explains why she prefers
    a clean and odor-free litter box.
  • 3:20 - 3:23
    That's less likely to give away
    her location to any predators
  • 3:23 - 3:27
    that may be sniffing around nearby.
  • 3:27 - 3:29
    Considering everything
    we do know about cats,
  • 3:29 - 3:32
    it seems that one of their most
    predominate behaviors
  • 3:32 - 3:34
    is still one of the most mysterious.
  • 3:34 - 3:38
    Cats may purr for any number of reasons,
  • 3:38 - 3:39
    such as happiness,
  • 3:39 - 3:40
    stress,
  • 3:40 - 3:41
    and hunger.
  • 3:41 - 3:44
    But curiously,
    the frequency of their purrs,
  • 3:44 - 3:46
    between 25 and 150 hertz,
  • 3:46 - 3:51
    is within a range that can promote
    tissue regeneration.
  • 3:51 - 3:55
    So while her purring makes Grizmo
    an excellent nap companion,
  • 3:55 - 4:00
    it is also possible that her purr
    is healing her muscles and bones,
  • 4:00 - 4:03
    and maybe even yours, too.
  • 4:03 - 4:05
    They developed through time
  • 4:05 - 4:08
    as both solitary predators
    that hunted and killed to eat,
  • 4:08 - 4:12
    and stealthy prey that hid
    and escaped to survive.
  • 4:12 - 4:15
    So cats today retain many
    of the same instincts
  • 4:15 - 4:20
    that allowed them to thrive in the wild
    for millions of years.
  • 4:20 - 4:24
    This explains some of their seemingly
    strange behaviors.
  • 4:24 - 4:26
    To them, our homes are their jungles.
  • 4:26 - 4:29
    But if this is the case,
    in our own cat's eyes,
  • 4:29 - 4:30
    who are we?
  • 4:30 - 4:34
    Big, dumb, hairless cats competing with
    them for resources?
  • 4:34 - 4:39
    Terribly stupid predators they're able
    to outsmart every day?
  • 4:39 - 4:41
    Or maybe they think we're the prey.
