A meow or miaow is a cat vocalization. Meows may have diverse tones in terms of their sound, and what is heard can vary from being chattered to calls, murmurs, and whispers. Adult cats rarely meow to each other. Thus, an adult cat meowing to human beings is generally considered a post-domestication extension of meowing by kittens: a call for attention.[1][2] Felines usually communicate with each other via their shared sense of smell, yet with people they often make verbal cues around behavior, such as having a specific sound indicate a desire to go outside.[3][2][4]
A mew is a high-pitched meow often produced by kittens.[5][6] It is apparently used to solicit attention from the kitten's mother,[7] and adult cats may use it as well.[5] The mew is similar to what is described in Brown et al. 1978 as an isolation call. By around three to four weeks of age kittens do not mew when at least one littermate is present, and at four to five months of age kittens stop mewing altogether.[8][9]
