A mummy is a deceased human or an animal whose skin and organs have been preserved by either intentional or accidental exposure to chemicals, extreme cold, very low humidity, or lack of air, so that the recovered body does not decay further if kept in cool and dry conditions. Some authorities restrict the use of the term to bodies deliberately embalmed with chemicals, but the use of the word to cover accidentally desiccated bodies goes back to at least 1615 CE.
Mummies of humans and other animals have been found on every continent, both as a result of natural preservation through unusual conditions, and as cultural artifacts. Over one million animal mummies have been found in Egypt, many of which are cats.
The earliest ancient Egyptian mummies were created naturally due to the environment in which they were buried. In the era prior to 3500 BCE, Egyptians buried the dead in pit graves, without regard to social status. Pit graves were often shallow. This characteristic allowed for the hot, dry sand of the desert to dehydrate the bodies, leading to natural mummification.
