             | 
             | When my cat wants something, she'll meow uselessly until we
             | chance on what it is. When my dog wants something, she'll
             | come to me and touch me with her paw, and I'll say "Food.
             | Water. Walk." and she'll bark at the one she wants. It's
             | amazing.

               | Cat IQ depends on the cat. We had an _incredibly stupid_
               | cat who liked nice but was dumb as a rock, and would
               | mostly sit in the kitchen staring at the far wall and
               | looking a bit dreamy. She didn 't really meow at all. Or
               | do much of anything else.
               | 
               | We had a couple of high IQ cats who not only knew how to
               | communicate they were also super-social, and made it very
               | clear to us and to visitors what they did/didn't want.
               | 
               | Now we have a mid-IQ cat who is quite vocal and quite
               | good at communicating, but we have to make more of an
               | effort than with the previous two.

               | While cats mostly do just meow (as much as you can say a
               | dog mostly just barks)... my cats definitely do have
               | variances to their meow depending on their needs or
               | wants.
               | 
               | When we stayed in an RV while the house was being built,
               | I had to put my fat boy Percy into the shower stall with
               | the doors closed while the dogs ate otherwise he would
               | annoy them (with headbutts) into not wanting to eat. He
               | developed a habit of going into the stall on his own and
               | meowing when he wanted to be fed because we always put
               | him into the shower when food would appear for the dogs.
               | 
               | Even in the new house, he jumps into the tub and meows
               | the same way when he wants to be fed.
               | 
               | He meows a different way when he sits at the gate or at
               | the top of the stairs, as if for permission to interact.
               | If you don't acknowledge him, he won't hop the babygate
               | or come down the stairs. If you do respond, he trills a
               | happy chirp and trots along.
               | 
               | He developed a whine meow where he basically is saying "I
               | need attention now." Most recently he did it because a
               | towel fell into his water bowl and he couldn't drink out
               | of it.
               | 
               | That counts as 'food, water, walk' to me.
               | 
               | Oskar also has various different behaviors associated
               | with meow types for things that get him the response that
               | he wants. But both cats are Sphynxes and they are
               | _unusually talky_... I doubt I would have gotten as much
               | from other breeds. But they do clearly communicate what
               | they want from you once they find a way to get that to
               | come across.

             | The eagles and coyotes (I live in the middle of the city,
             | go figure) would make short work of the cat if outside. The
             | coyotes often hang out on the front lawn, and recently left
             | a nice "you suck, Walter" message as a pile of poo by the
             | front door. Had a bobcat wander by not too long ago. The
             | coyotes don't approach me, but I'm not so sure about
             | bobcats.
             | 
             | A couple weeks ago a gigantic eagle cruised by me at eye
             | level, about 10 feet away. No way I'm going to tangle with
             | that monster, and it's easily big enough to cart off the
             | cat. The other cats in the neighborhood are indoor cats,
             | too.
             | 
             | Once there was a juvenile coyote cut in half in the front
             | yard. I figured it was that eagle.
             | 
             | Another time a ginormous owl decided to sit on the porch
             | railing, staring at me, for quite a while. Yeah, it could

             | Cats are a lot about body language.
             | 
             | For your question I just look at the ears and the tail.
             | When the ears go lower and/or tail starts wagging, I stop.
             | Or when my cat moves a small distance away, sits there and
             | stares/smiles? I stop.
             | 
             | I've noticed that what I interpret as a desire for petting
             | is often some other business. Maybe the litterbox is full.
             | Or maybe it's playtime (thinks the cat). Or something else
             | is amiss.
             | 
             | It maybe sounds stupid but when I can't read my cat, I
             | usually just ask. I say repeatedly "show me", "where",
             | "show me", "where" etc. and slowly walk behind my cat and
             | let it lead.
             | 
             | For example, if the balcony door is open and cold air is
             | coming in (my cat doesn't like cold), my cat sometimes
             | takes me to first to the fridge and then leads me to the
             | balcony door. When the litterbox is full my cat takes me
             | near it and sits there facing it, within visual/smelling
             | range, but never very close to it. And so on, one has to
             | connect the dots from the context, and ask the question
             | "what is there at this location that is meaningful to the
             | cat".
             | 
             | Of course sometimes I can't fix what my cat wants. Like
             | when the Sun has moved away and the sleeping place in the
             | chair has fallen under a shadow. So my cat tries a few
             | times, repeating the same behaviour, but eventually gives
             | up, either gets bored or realizes I can't or won't help.

           | The video where the cat begs (through the buttons) to go
           | outside in the rain, takes one step outside, comes back in,
           | and immediately complains (through the buttons) about the
           | rain, is pretty convincing to me.
           | 
           | Also interesting is its use of the "angry" button in response
           | to not getting its way, _or_ having something irritating it,
           | _or_ when it 's clearly frustrated by not having its needs
           | understood.

               | though, either. There's a number of videos in which
               | she'll barely touch or just hover her paw over a button,
               | pause for a while, take it away, and then proceed to push
               | a different button.

               | AFIACT, the videos are a kind of progress log for
               | demonstrating the cat's learning in different concepts.
               | The older videos focused on [demonstration of] learning
               | of more "core" concepts ("food", "water", "pets",
               | "outside", etc.); but since these concepts are now fully
               | "taught", the owner seems to feel no more need to film
               | the cat communicating these simpler core messages, except
               | when they form an interesting sequence or larger idea.
               | 
               | Instead, the newer videos focus on learning of more
               | fringe concepts -- ideas that "come up" less often -- and
               | so progress is slower in these.
               | 
               | (Note that, watching the videos chronologically, the
               | number of buttons the cat has available grows quite a bit
               | over time. I think the owner thinks that the cat now
               | understands the _general concept_ of associating things-
               | to-be-communicated with presses of word-buttons, and so
               | feels that they can now feed them new concepts faster.)

         | 
         | Also: "As a consequence, the actual range of frequencies we

             | 
             | Rather than taking aim at the sampling rate, if anything

         | Or is it intentional? Is there some scientific usefulness that
