I believe that all the cat family have innate feline patterns of behavior ..

... established over millions of years of evolution that are fascinatingly common to all species within the feline order - the way they establish territory, show affection, and communicate, for example - but that those patterns are overlain or added to in species or individuals that interact with humans, regardless of the extent of tameness or domestication.

Our 18-year-old indoor cat, Missy, for example, has many routines that relate to our household routines and activities; appears to understand (or at least react predictably and purposefully to) a range of spoken words; and is very vocal in a way that is not shared by the outside cats in the TNR'd feral colony that we care for. Some of the ferals, however, do come to us, even jumping briefly onto our laps, for affection as well as food; but they are rarely vocal and do not appear to speak to one another.

Back in my zoo-keeping days I had some opportunity to interact - very carefully and under the curator's or a vet's supervision! - with large cats (tigers and a leopard); and was fascinated by how some of those cats' behaviors (showing affection, and vocalization, for example) resembled those of domestic cats. I learned years later from a bioacoustical scientist who had studied them that tigers utter a similar range of vocal greeting and other sounds to that of domestic cats (maybe 20 or 30 distinct sounds) - except that big cats can roar but apparently can't or don't purr.

The particulalrly interesting thing reported to the Acoustical Society of America was that a majority of the sounds that are made by tigers that have been raised by or lived in some kind of relationship with humans are uttered only to (or in the presence of) people; and almost never to other tigers. The same is likely true of domestic cats' utterances: other than communications between mother cats and kittens, it seems that domestic cats mew to us a lot but rarely to other cats.

Possibly all these animals are trying to emulate or participate in human communication. The same may be true of barking in dogs. It appears that all of the non-domestic dog species (including wolves, coyotes, dingos and the like) share our pet dog breeds' vocal apparatus for barking but very seldom do bark in the wild.
