Cats "Exploit" Humans By Purring 503

An anonymous reader notes a BBC report on research recently published in the journal Current Biology, indicating that cats manipulate humans by adding a baby-like cry to their purring. "Cat owners may have suspected as much, but it seems our feline friends have found a way to manipulate us humans. Researchers at the University of Sussex have discovered that cats use a 'soliciting purr' to overpower their owners and garner attention and food. Unlike regular purring, this sound incorporates a 'cry,' with a similar frequency to a human baby's. The team said cats have 'tapped into' a human bias — producing a sound that humans find very difficult to ignore."

    Assuming that the cats are in fact intelligent creatures, it would make sense that they have learned this behavior. Feral cats do not exhibit this behavior, so it is most likely learned or self-developed.

    However, it could also be that the constant exposure to humans and the direct selection of cats which humans like the most by the owners has led to a selection bias for cats with this behavior.

    I find it hard to believe that this is somehow one of those hokey "100th monkey" behaviors, but I also find it extremely interesting that this behavior is widespread.

        > Don't forget that cats self-domesticated

        Thing is, cats *aren't* domesticated. They only pretend to be when it suits their purposes.

        If you want to see what domesticated looks like, look at dogs, or horses. Domesticated dogs and horses take their instructions from human masters. Cats, as a rule, don't.

        Cats live *among* humans and coexist more or less peacefully with them, but so do squirrels and houseflies. Cats accept food from humans and even depend on it as their main food source, but so do wild birds that eat at feeders. Cats will even occasionally approach a human and allow themselves to be petted, but only when it's their idea.

        There's a continual argument between people who prefer dogs and people who prefer cats, over which kind of animal is smarter. Of course, there's a great deal of variation in intelligence from one dog to another, and one supposes there may also be from one cat to another, but fundamentally the main reason this argument has never been resolved is because nobody can really demonstrate exactly how smart cats are, because the cats don't cooperate with the study. If you've got a dog, you can find out exactly how smart he is, based on what you can teach him. A monumentally stupid dog can learn about one trick, and then when you try to teach him another, he either can't figure it out or forgets the first one. On the other end of the scale, the most intelligent dog I've ever known recognized an English vocabulary of several hundred words and understood SVO sentence order. With a dog, you can find out exactly how smart he is, because he'll cooperate with the whole exercise. A dog is a social animal. His whole life is focused around *you*. A cat is altogether a different beast. A cat does what it wants, when it wants. You can try to teach it stuff, but as a rule the cat doesn't cooperate, so you can never really be sure what it's learned and what it hasn't.

          Actually, it isn't *that* difficult to train a cat. Most people just don't bother.

          • Yeah, mine wanted to get scratched every morning, so I trained him to listen for when the shower is done, wait a minute or so, and then come in. he sits patiently on the toilet seat, I scratch him for about 30 seconds to a minute and then say "All done", and he hops off and walks out. Before training him, he'd rub up against my leg all morning, driving me nuts. Now, I spend 1 minute giving him attention, he's happy, and I get my morning back.

          How much of this perception is expectation? I've had cats and dogs, and while I agree that dogs are easier to train, it is still possible to completely train your cats to respond to verbal and gestural commands. I think a lot of people don't even try to train their cats, or treat them like untrainable companions because that is what they expect. When the cat does something bad, instead of looking how to modify the behavior, people say "oh, that's cats for you!" and then give the cat attention (either negative or positive). I think one of the big differences between cats and dogs that set up this mentality is cats respond a lot better to negative attention than do dogs. When a dog is punished, he feels cut off from the pack, and while negative attention is slightly better than nothing for a dog, it has a more significant impact in reducing unwanted behavior when paired with intermittent positive reinforcement. Cats on the other hand, just like attention. When training them, you just can NOT punish bad behavior unless it is a serious transgression (knocking over the tv, smothering the baby, etc). Instead you have to focus on rewarding positive behavior. So, if your cat meows a lot, don't yell at him or squirt him because he then will continue to meow--he thinks you are talking or playing with him. Instead, wait until he stops and reward the silence. Cats are a little more like toddlers. In general, the most negative action I take is to ignore them, but then give them lots of praise and reward for acting in ways I approve. So don't say cats don't take instruction from humans. I think it would be more accurate to say dog and horse owners take more care to understand the psychology of their pets and put more effort in training them, and as a rule, give up on cats before they even try training because they have already jumped to the conclusion it's impossible.

          If you want to see what non-domesticated looks like, have a feral cat in your house for an hour or two. Or a feral dog.

          If you and your house survive, congratulations. Cats ARE, in fact, domesticated animals, as are dogs- because they have early and often human contact. If kittens (or puppies) are not handled frequently once they get beyond a certain stage, they won't recognize or trust humans.

      Well, as a cat owner I'm not surprised at all. My cat learned quite a few different sounds since I got her, initially it wasn't more than the common meow, but now she uses quite a few different purrs and grunts for different occasions. Like in the morning when feeding time takes too long it's almost like a dog growling in really short bursts, while when you get home it's a more like a high-pitch grunt or purr. I'm sure dogs have similar ways to show their feelings or try to communicate stuff. Cats know damn well what they can and can't do and what will happen when they act some way or another, so it's not a big step from different sounds for different events to learning that certain sounds seem to do trick.

Selecting cats for their purr is no more extraordinary than, say, the difference we've created between a spaniel and a Mexican Hairless.

      Well, cats and babies use what works. If a specific sound is what gets you going, then that's the sound you'll get when they want something. Which is why your approach is perfectly fine; as long as you know there's nothing really wrong, training them to sound like something's horribly amok all the time isn't desirable.

      On the other hand, sometimes it's good to reinforce nice ways of asking for attention. Personally I give in and play a bit when my cats roll over on their backs and purr (just far enough out of reach so I can't pet them), or when they bring their toys to me. Or I'll look what they want if they tug at my elbow. The only annoying sound that will get them something is the plaintive meow accompanied by scratching the floor near the litter box. That one means 'the litterbox is dirty, change it or I'm gonna piss on the floor', and considering they usually have a point and a reasonable tolerance, I'll accept that one.

    Just like some birds have learned to mimic the ring tones of mobile phones (and normal phones, too). There's no evolutionary pressure here, it's just that cats do have some (small - very small) glimmer of intelligence and learn that making certain noises will get them what they want. Babies also do this, so we're not talking about anything that's particularly difficult. Dogs are also known to respond to their names - though to to all the other chatter that their owners seem to think they'll understand.

    In fact, pretty much any animal - even my goldfish, can be conditioned to respond to a food stimulus - they know what precedes them being fed and act accordingly.

    The only surprising thing about this is that the cats haven't got their owners better trained in all this time.

    • Cats are very unusual in evolutionary terms. For solitary animals, they have remarkably well developed social skills. The ability to make a wide variety of vocal sounds is usually associated with social development and mating habits too.

      Clearly humans have not been a major factor in their evolution - we have not been domesticating them for nearly long enough. By chance they developed into cute, furry and agreeable little things that human beings enjoy having around. They are intelligent enough to manipulate us quite successfully and yet, despite being fully aware of what is happening we accept and even enjoy it. Being highly independent they have their own little lives which fascinate us.

      Maybe it's just anthropomorphism, but it's certainly highly fortunate from the cat's point of view. Average life expectancy in the wild is a few years, domesticated it's 10+.

    cats have not tapped into anything at any time. it was already their normal attitude. cats psychologically see humans as their mothers. both men, and women alike. it doesnt matter. therefore they do all stuff they do to their mothers, to their human companions. no surprise they also make that sound.

    to 'tap' into such a thing would require a cat to observe a baby, then imitate him/her. yet, how many cats that were in the research have observed a baby crying ? how many cats were raised with a baby ?

    this thing has to be just another instinctive behaviour cats do to their mothers at early age. i wonder why this schmuck didnt research whether baby cats also do that to mother cats.

    Then, maybe 12k-20k years ago, cats domesticated us, and the next thing you know, we're doing agriculture, and building civilization... so that they could live in the manner in which they intended to become accustomed.

    It's all their fault...
