10 Huge Prehistoric Cats

TyB . . . Comments

Before man became a hunter and made his way to the top of the food chain, the Felidae, or cats, were the most successful, powerful predators in most of the world. Even today, big cats such as tigers, lions, jaguars and leopards keep causing admiration and fear, but these magnificent beasts are dwarfed by some of their extinct relatives. I give you ten of prehistory’s largest, mightiest cats, some of which were seen by humans only a few thousand years ago.

10

Giant Cheetah

Pardinensis

The Giant Cheetah (Acinonyx pardinensis), belonged to the same genus as our modern day Cheetah (Acinonyx jubatus), and probably looked very similar, but it was much bigger.

At around 120-150 kgs (265-331lbs), it was as large as an African lioness, and was able to take on larger prey than its delicate modern day counterpart.
The Giant Cheetah was also adapted to fast running, but there’s some debate on whether it could run as fast as the modern Cheetah, due to its larger weight, which, according to some, probably made it somewhat slower.

Others, however, have suggested that the Giant Cheetah, having longer legs and bigger heart and lungs, was probably able to run as fast, or even faster, than the cheetah does today – that’s over 115 kph (72mph)! The Giant Cheetah lived in Europe and Asia (from Germany and France to India and China) during the Pliocene and Pleistocene epochs; it went extinct during the last Ice Age. Due to its living in colder environments than modern day Cheetahs, it is possible that the Giant Cheetah had longer fur and perhaps a lighter coloration.

Xenosmilus

Screen Shot 2010-12-02 At 11.12.11 Am

Xenosmilus is a relative to Smilodon (the ever famous “sabertoothed tiger”), but instead of having long, blade-like fangs, it had shorter and thicker teeth. All of its teeth (not only the canines) had serrated edges to cut through flesh, and were more like the teeth of a shark or a carnivorous dinosaur, than the teeth of modern day cats.

Xenosmilus didn’t strangle its prey as modern day cats do; it only had to bite off a huge chunk of flesh from its victim, and wait until it bled to death. A Xenosmilus’ kill was much bloodier and messier than that of any big cat today!

Xenosmilus was a very big cat for today’s standards; at 180-230 kgs (397-507lbs), it was as big as most adult male lions and tigers, and was much more robust, with shorter, stronger limbs and a very powerful neck. The remains of this cat have been found in Florida, along with those of giant prehistoric peccaries (pig-like animals) which were seemingly its favorite meal. It lived during the Pleistocene period but no one knows exactly when it went extinct; whether it encountered (or ate) humans or not is anyone’s guess.


8

Giant Jaguar

Jaguar Augusta

Jaguars today are rather smallish cats if compared to lions or tigers; they usually average 60-100 kgs (132-220lbs), and the largest males (recorded from South America) were around 150 kgs (330lbs), about the size of an African lioness. In prehistoric times, however, both North and South America were home to gigantic jaguars, belonging to the same species as modern day jags (Panthera onca) but much bigger.

These giant jaguars also had longer limbs and tails than jaguars living today; scientists believe that jaguars used to be open plain denizens, but that competition with American lions and other big cats forced them to adapt to more forested environments, where they developed their modern short-legged appearance.

Giant prehistoric jaguars were about the size of a fully grown lion or tiger, and were probably several times stronger, with a much stronger bite.

There are two subspecies of prehistoric giant jaguars known to date; Panthera onca augusta, from North America, and Panthera onca messembrina, from South America (also known as the Patagonian panther). Both of them were active during the Pleistocene period, but went extinct about 11.000 years ago, during the last Ice Age.

7

European jaguar

76702014

Unlike the Giant Jaguar mentioned before, the European jaguar or Panthera gombaszoegensis did not belong to the same species as modern day jags. Nobody knows what the European Jaguar looked like; some scientists have suggested that it probably looked much like a modern day jaguar (hence the name), or perhaps, a cross between a lion and a jaguar. A fossil feline from Eastern Africa has been said to resemble the European jaguar, and described as having “tiger-like” features as well.

Regardless of its external appearance, it is obvious that it was a huge predator, weighing up to 210 kgs (463) or more, and probably at the top of the food chain in Europe, 1.5 million years ago. Its fossil remains have been found in Germany, France, England, Spain and the Netherlands.

6

Cave lion

Cave-Lion

The Cave lion was a gigantic subspecies of lion, weighing up to 300 kgs (661lbs) or more (and therefore, being as large as the Amur or Siberian tiger, the largest cat of our days).

It was one of the most dangerous and powerful predators during the last Ice Age in Europe, and there is evidence that it was feared, and perhaps worshiped, by prehistoric humans. Plenty of cave paintings and a few statuettes have been found depicting the Cave Lion. Interestingly, these show the animal as having no mane; barely a ruff around the neck sometimes, as in modern day tigers.

Confusingly, some cave paintings also show the Cave Lion as having faint stripes on its legs and tail. This has led some scientists to suggest that perhaps the Cave Lion was actually more related to the Tiger. Genetic studies on the ancient bones, however, have confirmed the original idea that the Cave Lion is, indeed, a lion after all – albeit, if cave artists are to be trusted, a very unusual looking one.

5

Homotherium

Homotherium

Also known as the “Scimitar cat”, Homotherium was one of the most successful felines in prehistoric times, being found in North and South America, Europe, Asia and Africa. It adapted well to a variety of habitats, including the sub-arctic tundra and survived for five million years until its extinction 10,000 years ago.

Homotherium was seemingly a pack hunter, adapted to fast running and active mostly during day (thus avoiding competition with other, nocturnal predators). It had very long forelegs and shorter hind legs, which gave it a slightly hyena-like appearance. Although Homotherium is not very famous for its size, some fossil remains of a Scimitar cat unearthed recently in the North Sea suggest that they could reach 400 kgs (882lbs) in weight, being larger than modern day Siberian tigers.

If you are wondering what these enormous, pack-hunting cats ate, some paleontologists believe that they were quite skilled mammoth hunters, although their ability to run at high speed would allow them to chase after fleet-footed animals as well.

Machairodus kabir

Very  Very Big Cat By Hodarinundu-D332Oxj

Despite Smilodon’s fame as the classic “sabertooth tiger”, its short tail and different body proportions were very different from an actual tiger.

Machairodus, on the other hand, probably looked pretty much like a gigantic tiger with saberteeth; it had very tiger-like proportions and a long tail, although it is impossible to know if it had stripes, spots or any other kind of fur markings.

Machairodus is seldom mentioned as a giant feline, but some fossil remains found in Chad, Africa, (and classified as a new species, Machairodus kabir), suggest that this creature was among the largest cats of all times- weighing up to 490 (1080lbs) or perhaps 500 kgs (1102lbs), and being “the size of a horse”. It fed on elephants, rhinos and other large herbivores which were abundant at the time.

Machairodus kabir probably looked somewhat like the gigantic “sabertooth tiger” in the film 10.000 B.C, although sadly, it went extinct during the Miocene period, long before the appearance of humans.

3

American lion

Page18A

Often called the largest cat of all times, the American lion or Panthera atrox, is probably the best known of all prehistoric cats after Smilodon.

It lived in both North and South America (from Alaska to Peru) during the Pleistocene epoch, and went extinct 11,000 years ago, at the end of the last Ice Age. Most scientists believe that the American Lion was a gigantic relative to modern lions, perhaps even belonging to the same species (in which case the correct name would be Panthera leo atrox).

However, others are not so sure, and suggest that the American lion, although closely related to the lion, was a separate species and probably looked quite different on the outside. Recently, it was suggested that the American lion was probably more similar to the jaguar.

One thing is certain; the American lion was the largest cat in North America during the Ice Age, weighing up to 470 (1036lbs), perhaps even 500 kgs (1102lbs), and being able to take on very large prey. There is still some debate about its hunting technique, for although modern day lions hunt in groups, American lion remains are scarce, suggesting that these cats were probably solitary hunters.

This would make sense if we consider that the North American Smilodon fatalis, a species of sabertooth, was seemingly a pack hunter. By hunting alone and preying on different animals, it may be that the American lion avoided competition with the sabertooth, explaining why both cats coexisted successfully for such a long time.

Pleistocene tiger

Img 0023

This is easily the most obscure cat in the list, being known from fragmentary remains which have yet to be formally described. I should mention that the “Pleistocene tiger” is not a separate species, but rather the “early version” of the same tigers we see today. Tigers evolved somewhere in Asia about 2 million years ago, specifically to prey on the enormous diversity of large herbivores living on the continent at the time. Tigers are the largest felines nowadays, with large Bengal and Siberian males reaching up to 300 kgs (661lbs) or more.

However, during the Pleistocene, the food supply was greater, and so the tigers themselves were bigger. Some fragmentary remains (including massive jaws and fangs) have been found in Russia, China and Java, suggesting that these “Cave tigers” could reach up to 490 kgs (1080lbs) in weight, being worthy contenders for the title of largest cat ever.

1

Smilodon

Smilodonsabretoothcat

The ever popular “sabertooth tiger”, Smilodon is one of the most famous prehistoric predators, and also one of the most formidable.

There were at least three species living in both North and South America; the smallest species, Smilodon gracilis, was about the size of a modern day jaguar, while Smilodon fatalis was as big as a lion.

However, the South American species Smilodon populator dwarfed both of them, weighing 300 kgs (661lbs) on average and reaching up to 500 kgs (1102lbs) when fully grown!
Smilodon was not as agile as modern day big cats, but it was immensely powerful, with thicker, stronger limbs and neck than modern day cats, and particularly long claws to hold on to prey. Its fangs could reach 30 cms (12″) in length, and were perfect for causing mortal injury to mammoths, ground sloths and possibly any large animal unlucky enough to be ambushed by this super predator.

Smilodon went extinct 10,000 years ago, meaning it encountered humans, and probably hunted them once in a while. But perhaps the most amazing thing about Smilodon, is that it is the only prehistoric cat known to have caused the extinction of an entire species. The victim was another formidable predator, the saber-toothed marsupial or marsupial relative known as Thylacosmilus.

This beast ruled South America for millions of years, until the sea levels became lower and North America became connected to South America.

Smilodon, native to North America, made the journey to South America about 2 million years ago. Thylacosmilus disappeared practically at the same time, outcompeted, and perhaps even, hunted to extinction by the cat. In other words, Smilodon basically conquered an entire continent, driving its less adaptable competitors to extinction, therefore its place as #1 in this list.

    I love you listverse! You make sleepless nights easy to deal with :D

  • timothyjames

    I'm so surprised that this list hadn't already been written. But since it wasn't, I can't think of a better person to tackle it than TyB. Another fantastic animal list.

    I think I read somewhere that panthers and jaguars are the same animal. Or maybe that black panthers are just jaguars with black fur and darker black spots. Can anyone confirm or deny?

    • ianz09

      Yes, kind of. Black panthers aren't a specific species. When a cat is melanistic, it has black fur, and I believe skin as well. In South America, black panthers are in fact jaguars, in Africa they are leopards, and in North America can be jaguars or cougars. Panthers are not a specific species, but a genus which contains lions, jaguars, and leopards. I already knew all this from a while, but definitely had to double check my facts. But there you go!

      • timothyjames

        Perfect. Thanks!

  • cqsteve

    Imagine what the cave dwelling forebears of modern man, the Neanderthals, Homo Erectus etc had to put up with. "Just going out hunting, sweetie, is there anything you want me to pick up". "No, but watch out for the Cave Lions – they've been pesky lately". Shit – they were armed with nothing but clubs, spears and sharp rocks! I would have stayed in my cave & starved.

    • Lololol

    The giant cheetah and jaguar scares me a bit. After reading it I imagined myself face-to-face wih them … not good!

  • rain

    I think I've seen this list before. Here on Listverse too.

    • timothyjames

      I thought so too, but I did a quick search of the archives, and I think we are confusing it with the "10 Amazing Big Cats" list.

      • TEX

        There was also "10 Creatures With Saberteeth " Tyb did in Sept.

  • bluesman87

    Nice list , Tyb been long . With regards to no.1 did its Jaw open wider in order to use those long ass fangs ? Or did it use them walrus style ? they are huge and scary looking but they also look awkward .

    • kubrick

      it's an artist's conception, chap
      not a photograph

    • agar

      It did, it could almost open its mouth 180 degrees. Its jaws would lock into place in its spinal collum so that when it punctured the prey the tremendous force would move down the spinal collum, keeping it from breaking its neck

  • unholy shiet

    Weak list

    I would love to have a tiger/lion/jaguar/cheetah as a pet … If only they weren't dangerous *sigh*

  • ianz09

    I guess since El isn't around much and has graduated to legitimate contributor anyway, and br0ck has somehow been consistently getting thumbs up to a significant portion of his comments lately, we needed a new troll who exists purely to troll. Welcome to Listverse, Kubrick.

    • Jay

      I didn't really see br0ck as a troll, i felt like he simply spoke his mind, which i like. But this kubrick person just has too much time on his/her hands because the comments aren't even funny. If you're gonna be a troll, atleast be somewhat creative and funny :D

      • ianz09

        Perhaps we can consider br0ck an accidental troll?

        • Maggot

          There is nothing “accidental” about being a racist and a homophobe. Which he is.

          • ianz09

            True, true. I hadn't thought about the racism and homophobia. I was recalling his constant barrage of comments that generally went like, "This list sucks because whaa whaa whaa".

      • kubrick

        …i think i'm pretty funny
        wanna hear a joke
        so i walked into a store and asked "can i use your dictaphone?" the man said no, just use your fingers like everyone else.
        OH SNAP i came up with that too

        and just so you don't delete this comment
        i'll post something list related
        what's the difference between a pleistocene tiger and a regular tiger?

        • Maggot

          OH SNAP i came up with that too

          Liar. A quick search will find the dictaphone joke all over the web. Just like your “abbreviation for abbreviation” retread yesterday. Maybe the reason that you bomb as a comic (as you said so yourself) is because you steal others’ material and regurgitate it as if it were your own.

          • kubrick

            I just looked up the dictaphone joke on google…the only thing I could find was a male secretary saying "feel free to use my dictaphone." Which I guess is kinda the same, but not really. the joke I wrote I came up with completely

          • Maggot

            the only thing I could find was a male secretary saying "feel free to use my dictaphone."

            And what was the punch line to that one? You should know, since “your” version plagiarizes it practically verbatim. Changing a word or two in the set-up does not make it your own fresh new joke.

            Which I guess is kinda the same, but not really.

            No, it’s really the same. Not even kinda.

            the joke I wrote I came up with completely

            Just keep telling yourself that…

          • kubrick

            I don't think you understand…I never saw the joke on the internet before. I have no idea who this male secretary is. I came up with the joke by myself and it just happened to have already been created by someone else.

    • TEX

      Br0ck is getting thumbs up because we agreed to get his red thumbs score down – that is how he rated himself, with negative responses.
      Now it's time to take him to zero – as far as that other kid – just ignore him – no responses – with no attention he'll go away

  • ianz09

    Is the word Kubrick tagged to send your comment into moderation? The 'K' word?

    • kubrick

      lulzwut

      • ianz09

        lulzwut is that when I posted my previous comment, it went into moderation. So I guessed that either the word 'troll' or the word 'kubrick' was flagged for moderation. And sure enough, when I posted this second comment that you replied to, it got flagged. Since I didn't say 'troll' in the second post, your name is flagged for spam. Congratulations, you reached an all new Listverse low.

    why are my comments being deleted

    • timothyjames

      Because you're a troll, and the comments you post are considered trolling. If you post things that aren't offensive or that are related to the list, they don't get deleted. Just yesterday you were doing fine. I hope you gain the mental faculties to help you determine what is appropriate and what is not, but if you don't, well don't worry – you'll always have us.

      • cqsteve

        Ignore him timothyjames, he might eventually go away.

    • timothyjames

      There are still plenty of comments by you up there that I left. Plus there are other admins and moderators, so I can't guarantee that anything is here to stay. I only deleted ones that were trolling. The one with the joke is close, but I laughed, so whatever.

    • Sailor

      You're not hilarious, in fact you're not even a little bit funny. You're annoying, immature, your comments are asinine, in short you are the worst troll I have ever seen on this site. Even brock occasionally makes a comment that shows some insight and he has the sense to know when to quit. Get a life fool. I know I'll probably get some thumbs down for this but I don't care because unlike you I'm not in it for the attention. You put me in mind of a small child who knows that if he makes enough noise people will give him the attention he craves, good or bad. You must have a very tiny ego if you crave attention this much.

  • Will Trame

    Those two smilodons in picture number one look like they’re ready to kill each other. This territorial competitiveness also applies to the modern day cat. Despite being cute, they have a feral streak in them that can come out when they’re provoked. The calico cat’s personality is prime example of this tendency. Good list.

    • TEX

      Calico is a coat color, not a breed – I am owned by two calicoes.
      But, quite interestingly – the tri-color pattern is determined by the X-X (female) chromosomes, so virtually all calicoes are female. The behavior you observed might just have been female feline behavior. Females that are in kitten protect mode can be VERY aggressive, even to big toms.

  • saber25

    Looks kinda like my list back then…

  • oouchan

    Awesome list as always, TyB! If they ever clone extinct animals, they need to start with a sabertooth. Not a dino!
    Excellent read, this morning. :)

  • In number 8 (the giant jaguar): "Both of them went extinct during the Pleistocene period, but went extinct about 11.000 years ago, during the last Ice Age."

    How can they get extinct after they got extinct? The Pleistocene ended 12,000 years ago and jaguars (somehow) lived for 1,000 years more, i don't get it

    I think it should be 'they both lived during the Pleistocene Period but went extinct about 11.000 years ago, during the last age'

    • mom424

      Sorted.

  • lords8n

    I think i'll call Kubrick "Kubby" and keep it as a pet!!!

    This list is ok, but I can't stand when these scientists speculate on things about an animal's life that they really don't know as fact. What if Thylacosmilus just got deadly perhistoric fleas (the size of American footballs) and that wiped it out…they don't know…HERESAY!!!

    • mom424

      lol, No not hearsay or heresy either. It's an extrapolation or an educated guess or maybe even an inference – a conclusion or opinion formed because of known facts or evidence. With what they know, competition/predation is the best explanation available.
      ps – Kubby is kinda cute – good call.

        Yeah I'm cute
        way to hit on me mom

        • kubrick

    Worst list yet.

  • mom424

    Great List Tyb – Like waking up to you in the morning.
    Amazing that humans were alive when many of these critters were roaming about. I agree with cqSteve – we're all a bunch of wimps nowadays, that's for sure.

    • Mr Sarcastic.

      Absolutely fantastic summary today mom424! You really made my reading experience much better today and I am so thankful that you commentated! Listverse wouldn't be the same without you!

  • chichirica

    wish I could get one of these cats so the neighbors' chickens won't bother my flower garden anymore.

    • Maggot

      True this will likely result in a chickenless neighbor, but then when one of these cats decides to use your flower garden for a litter box, you've got another problem on your hands.

  • Bernard Marx

    Is anyone else aware of the fact that tigers are probably going to be extinct in the next 20 to 30 years.

    • chrom3d

      yup, they're one heck of an expensive medicine and coat..

  • Sune

    Since I am a cat person I loved the list. IMO the best of this week.
    I bet my cat descended from one of these big guys, the little monster can take on all of the dogs of the neighborhood.

  • chrom3d

    I bet Garfield can kick their asses..

  • TEX

    Same here Sailor –

    I’ve had this cat since he was a kitten – named him Wild Thing when he was 8 weeks old because he thought he was a mountain lion. Had him neutered @ 3 months, now he’s 18 lbs of pure muscle.
    He currently devotes most waking hours to defeating the mouse conspiracy that looms in his mind (they’re everywhere you know).
    The bathtub has become his gladiator pit – catch a mouse, run to porcelain stadium, let the games begin!
    No joke – this a.m. – go to shower – blood streaks, mouse bits, and cat vomit (he insists on trying to eat them, then promptly throws up).
    Happens once or twice a week, there’s a bit of mouse stuck in the drain as I write.

    • Sailor

      That's too funny. I have a mental picture of the cat running to the tub with a mouse in it's jaws, dropping it in then doing his thing. I have similar issues with the vomit except he likes to eat cellophane, when he brings that up the rest of his stomach contents come up with it. For some reason he feels that right in front of my bedroom door is a good spot to do this. Bare feet in cold cat puke first thing in the morning. That'll make your day.

    Where my dawgs @ ? What a list ! Indeed we will brace ourselves for sleepless nights the festive season

    DYLAN:STAY AWAKE DUDE ! TYB…U got it !!!!

  • TEX

    Another great list from Tyb – thanks
    However – I question the very first line stating man as "the top of the food chain".

    • ianz09

      Eh, we are though. But if we didn't have guns and tools to help us hunt, we would definitely be lower down. Shooting a leopard? Effective. Punching a leopard? Not so much

      • TEX

        That’s sort of my point –
        Man versus blue whale – major fail
        Man vs. eagle at 5000ft – major fail
        Man vs. deadly virus – major fail
        Man vs. emperor penguin @ 40 below – major fail
        Etc. etc.

  • Carole

    I'm glad they are no longer around !!

  • bluesfan1875

    The extremes of nature are always fascinating. Great list

  • Lifeschool

    Smile-o-don – is that how you say it?? Great to see a TyB list again, keep it up.

  • ricej1969

    I have a problem with the assumption of #1 presented as a fact. Just because the Thylacosmilus became extinct around the same time doesn't mean that the Smilodon did it. Maybe a disease killed them off. Something else could of done it such as it's food source. I just get tired of people stating a fact with no proof. I'm not saying the the Smilodon couldn't of done it, as what was stated, but I think that it was a big assumption with no proof. Especially when we are talking in millions of years.

    Hello, Listversers! I've been faithfully visiting listverse for a couple of years now, but I've never taken the time to comment. I just wanted to say kudos to TyB, who always submits well-researched and interesting lists, and I say that as someone who isn't the biggest "animal lover." Keep them coming!
    P.S. DON'T feed the trolls, guys. As much as I love a good troll, and I do tend to find humor in trolling, one of the biggest rules of the internet is to just ignore them. People who comment endlessly have nothing better to do all day long, and are just looking for love and attention in other forums. Don't give them love and attention, they will go away and look for it elsewhere. Voila!

    • mom424

      Welcome! And I agree, although I must admit to failing at it now and again. Sometimes I just can't resist.

  • redwolfblack

    even though i hate cats,this was a good list. keep it up!

    • TEX

      cat hate is a taught behavior – your father right??? be honest

      • redwolfblack

        OHMIGOD, how did you know?!?!

  • “ODHI”

    Good list,Fist time for moderation;guess have to pull up my sockz !

    • mom424

      must have been a snafu….if you sign in through intense debate or wordpress maybe we can see that that doesn't happen again.

  • ajokeinabottle

    Love the list! If i could only like this list. Please make a thumbs up and down of a list, for we can see whether it is liked or not by your viewers!

  • Douglas Trent

    The male jaguars I am researching, Panthera onca palustus, reach at least 195kg (429lbs.) and are perhaps the giant jaguars mentioned here, still alive!

  • FlameHorse

    My fave is the American Lion. I love lions and horses, and what better than a lion the size of a horse?

    • General Tits Von Chodehoffen

      And don't forget it is instantly 2x cooler because it is American!

  • Bernard Marx

    Does anyone else CARE that tigers are probably going to be extinct in the next 20-30 years?

    • TEX

      if you are wondering why you didn't get much of a response the first time you posted it – it's because people are being polite – if you know of the programs for conservation and breeding of tigers then you would know that you statement is false –

      • bluesman87

        nope on the news it said that wild tigers would be extinct in twenty years if these damn poaching assholes dont stop killing and eating them, to get "strength" . Eating tigers , thats retarded .

  • deeeziner

    Meee_Owwww!!! TyB!!!!

    Just TRY to yiff these furries!! 8 0

    I saw an American Puma in the wild, once, when I was a kid. The size of the beautiful beast made an impression on me that has never left. To think that all of these beasts dwarf such a big cat is an awesome vision. Scary, but awesome.

  • alexjamesk

    Great list, TyB. Well-researched, concise, and always interesting.

    My favorite contributor to Listverse, by far.

  • santa

    huh

  • General Tits Von Chodehoffen

    Nice list. Those are some bad motherfuckers!

  • allyb10

    Haha, yeah, I'm definitely more entertained by some of them than I should be, but that's just my immature sense of humor shining through. But usually I'm too lazy to respond with a comment!

    • allyb10

      Whoops! That was meat to be a response to mom424 above, but my dumb self posted this comment wrong. I guess it shows that I don't participate in the forum much! Sorry everyone.

  • Roflwaflz

    Any one else getting list Deja vu? I just skim through all these "new" lists eh…

  • Bryan J

    Good list.

  • Top Kill

    I think i have seen a similar list here. But it doesn't matter. It is a great list.

  • i love lists related to animals….

  • Morgan

    Gorgeous. Wish they were still here. All of them.

  • I tried to submit a comment previously, but it has not shown up. I believe your spam filter may well be broken?

  • Stephenson R

    I like this list too much! Here’s a question I’d like to ask: Why does the cat love fish so much and yet afraid of water? How did they develop a taste for water-type animals particularly fish but “hydrophobic” at the same time?

    • TyB

      Cats are not afraid of water; they avoid it because their fur loses its insulating properties when wet, and they hate being cold. When fishing, they usually stay in the shore and use one paw to catch fish.
      There are of course exceptions and some cats like fish so much that they are even willing to dive for it.

  • paul

    weres the barbary lion?

    • TyB

      I didn´t include it because it lived through historical times.

  • romanian

    imajin swinging on the swing at the playground you look up hearing screams from your sister and see a sabertooth tiger surrond by your sisters limbs with blood every where your sister thought is was a nice kitty would you sit there staring at it scream or run think about it

  • Lio

    The Pleistocene tiger is way smaller than the american lion!

  • Shayne Crisci

    I’ve read some good stuff here. Definitely worth bookmarking for revisiting. I wonder how much effort you put to create one of these wonderful informative website.

  • david

    these are some really big………..cats
