An ocean (from Ancient Greek Ὠκεανός, transc. Okeanós, the sea of classical antiquity) is a body of saline water that composes much of a planet’s hydrosphere.
Domestic cats use many vocalizations for communication, including purring, trilling, hissing, growling/snarling, grunting, and several different forms of meowing.
A cat’s gastrointestinal tract is adapted to meat eating, being much shorter than that of omnivores and having low levels of several of the digestive enzymes needed to digest carbohydrates.
The tail and ears are particularly important social signal mechanisms in cats; for example, a raised tail acts as a friendly greeting, and flattened ears indicates hostility.
