Grice, who lived in Berkeley, owned three cats: Sausalito, Oakland, and Moraga. "Cat communication", wiki tells us, "is the range of methods by which cats communicate with other cats, humans, and other animals." Of course, Grice spoke of 'pirots'. These were his rewrite of 'parots'. A 'talking pirot' is a pirot which communicates with another pirot. So cat-cat is the obvious, natural, way to analyse natural expressions of intentions, rather. "Communication methods", the wiki notes, "include postures, movement (including "quick, fine" movements not generally perceived by human beings), and auditory and chemical signals. The communication methods used by cats have been affected by the domestication process." --- for which 'humanisation' may be a better term. "Cats vocalize with purrs, growls, hissing and meows." Griceian definition of 'a meow': "A meow is an expression utterered on occasion by a cat to signal a request to their mother." ********************************************** An adult cat will not meow to each other. *********************************************** -- it belongs to 'developmental pragmatics', then. Griceian definition of "a purr" "A purr is an expression uttered made by most species of felids, and not just felis domesticus." "A tonal buzzing can characterize differently between cats." "Domestic cats purr in a frequency of 25-150 vibrations/second." "Purring is often understood as signifying happiness". Vide, Grice, "The Aristotelian theory of happiness -- applies to cats?" --- "However, cats sometimes purr when they are ill, or during tense, traumatic, or painful moments." Geary proposes to qualify the idea of happiness here ("Humans happy? Pigs are happy!" -- "Happy-cat is still a different 'animal', or a 'horse of a different colour'). "There is no unique anatomical feature that is clearly responsible for the expression of a purr, which thus becomes a multi-modal Griceian expression." "A cat hisses and arches its back". A natural expression of her wanting "to make herself appear larger" -- A natural expression of her wanting "to ward off a threat". A cat kneads a blanket before a nap. The forward position of the whiskers "indicates" either happiness or curiosity (or both). A cats growls or hisses when angered or feeling threatened, which serves as a warning to the offending party." The Griceian mechanism involves three stages: 1. the cat's intention to display her feeling. 2. the Griceian mechanism: the display is effective on account only of the recipient of the signal ---- to identify the source of the feeling as being 'intentional'. 3. no 'sneaky' (prevarication) elements involved -- [* as in types of plover where the point is to _mislead_ the addressee] If the cat-utterer's warning is not heeded, a more serious attack may follow." "A cat may engage in behaviour or batting with their paws, with claws either extended or retracted." "When observing, or stalking, prety, a cat sometimes makes a chirping or chattering noise." -- This requires a Griceian explanation ("It can't be to warn the prey. It may well be unevolutionary and unintentional). The cry of a cat in sexual heat is called a caterwaul -- but not by the cat herself. A cat communicates a variety of messages or expressions using body language. In fact, proxemics is all there is, since all there is to a cat is her body. So that all expressions on the cat's part are 'bodily' in this respect. Examples of typical proxemics include arching the back as a signal of fear or aggression. Also, slowly blinking to signal relaxation. A cat that chooses to lie with its stomach and chest exposed conveys trust, and comfort. However, a cat may also roll on its side or back to be able to defend itself with all four sets of claws. Usually other signs (or 'utterances', in Grice's narrow use of the expression) (like ears and whiskers folded backwards) give an indication of the cat's overall humour. Flattened ears mean that the cat feels threatened, and may attack. Here we see Grice's distinction, 'exhibitive' ("I feel threaten") and 'protreptic' ("I may attack") rolled into one. Mouth open and no teeth exposed suggests a feeling of playfulness. The tail, as well is often used as a signaling mechanism. ("Not in the Manx cat, which lacks it" -- Geary notes, "Feline implications and implicatures" -- "The lack of a tail in a Manx cat _implicates_ *silence*"). A tail held high suggests confidence, or can be used as a greeting towards other cats -- usually close 'relatives' only. A half-raised tail, on the other hand, shows less pleasure. Unhappiness (in this 'feline' Aristotelian variant) is indicated with a tail held low. In addition, a cat's tail may "wag" or move rapidly to express a state of conflict. This confused Alice ("A dog wags his tail for reasons different than a cat's; a cat groans for reasons different than a dog"). "Avoid ambiguity": A cat with tail held high and twitching shows excitement, but this is often totally mistaken for anger. (Against Helm, I would blame the interpreter here, never the utterer). A cat will twitch the tips of their tails when hunting or when irritated, while larger twitching indicates displeasure. A cat may also twitch her tail when playing. A scared (or surprised) cat may puff up its tail, and the hair along its back may stand straight up and the cat will turn its body sideways to a threat, in order to increase its apparent size. Tailless cats, such as the Manx, as we were saying, which possess only a small stub of a tail, move the stub around as though they possess a full tail. ("A tail ends up being 'implicated' only, since it has been _cancelled_" -- Geary). Touching noses is a friendly greeting for cats. A lowered head is a sign of submission. Some cats will rub their faces along their guardian's cheek, hands, or ankles. While this is interpreted, wrongly, by the Homo Sapiens as a friendly greeting or sign of affection, the 'expression' displays 'natural' "meaning" only, as the cat's only way of "marking her territory", leaving a scent from the scent glands located in the cat's cheeks. More commonly, cats do something called a "head bonk", or "bunting", where they literally bump someone with the front part of their heads to express some sort of affection. Cats also lick each other. Cats lick each other to groom one other and to bond. This grooming is usually done between cats that know each other very well (in the usage that cats apply to 'very well'). A cat may paw a soft object on which they may be sitting, with a kneading motion. A cat uses this action alongside purring to show contentment. But it can also indicate curiosity. A cat may also do this when in pain or dying, as a method of comforting itself. (the chapter of a 'cat in pain' is Wittgenstein's territory). It is *instinctive* to cats -- where 'instinctive' is a Griceian neologism, almost. Cats use it when they are young to stimulate the mother cat's breast to release milk during nursing (Consequently, cats hand-raised by human beings do not exhibit this behaviour.) Pawing is also a way for cats to mark their territory. The scent glands on the underside of their paws release small amounts of scent onto the object being pawed, marking it as "theirs" the same way they urinate ('pee', in the vernacular) to mark their territory. Since the nature of the activity is, again, an "instinctive" (not implicatural) response related to the mother's care for the kitten, it may be an expression of need, indicating the need for some attention from the caregiver. Although a gentle bite can signify playfulness, bites that are accompanied by hissing or growling do not "signify" playful behavior (where 'signify' is Latinate for Grice's "mean"). When cats mate, the male tom bites the scruff of the female's neck as she assumes a position conducive to mating. Cats can also communicate (or 'mean' this or that, even via implicature) through scent via urine ('pee'), feces ('number two'), and chemicals in skin glands located around the mouth, tail, and paws. Cats also use scent in order to mark their territory. If another animal (e.g. Geary) tries to get in the cat's territory, she will fight for the territory, or the cat will scare the animal (e.g. Geary) off. Urine spraying is also a territorial marking. It is not 'meant' as "rude", necessarily, but adapted evolutionarily. Cats rub up against stuff to mark the items as "theirs". When cats rub a speciment of Homo Sapiens (who shares lodging with them), they are marking them with their scent, and picking up the people's scents ('what have you been up to?').
