Aden (/ˈɑːdɛn/ AH-den; Arabic: عدن ʻAdan‎) is a seaport city in South Yemen, located by the eastern approach to the Red Sea (the Gulf of Aden), some 170 kilometres east of Bab-el-Mandeb. Its population is approximately a million people. Aden's ancient, natural harbour lies in the crater of a dormant volcano which now forms a peninsula, joined to the mainland by a low isthmus. This harbour, Front Bay, was first used by the ancient Kingdom of Awsan between the 5th and 7th centuries BCE. The modern harbour is on the other side of the peninsula.

Aden consists of a number of distinct sub-centers: Crater, the original port city; Ma'alla, the modern port; Tawahi, known as "Steamer Point" in the colonial period; and the resorts of Gold Mohur. Khormaksar, located on the isthmus that connects Aden proper with the mainland, includes the city's diplomatic missions, the main offices of Aden University, and Aden International Airport (the former British Royal Air Force station RAF Khormaksar), Yemen's second biggest airport. On the mainland are the sub-centres of Sheikh Othman, a former oasis area; Al-Mansura, a town planned by the British; and Madinat ash-Sha'b (formerly Madinat al-Itihad), the site designated as the capital of the South Arabian Federation and now home to a large power/desalinization facility and additional faculties of Aden University.

Room 8 (1947–1968) was a neighborhood cat that wandered into a classroom at Elysian Heights Elementary School, Echo Park, California. He would live in the school during the school year and then disappear for the summer, returning when classes started again.

News cameras would arrive at the school at the beginning of the year waiting for the cat's return; he became famous and would receive up to 100 letters a day addressed to him at the school. Eventually, he was featured in a documentary called Big Cat, Little Cat and a children's book called Room 8 was written as well. Look magazine ran a three-page feature by photographer Richard Hewett in November 1962, titled "Room 8: The School Cat". Leo Kottke wrote an instrumental called "Room 8" that was included in his 1971 album, Mudlark.

As he got older, he was injured in a cat fight and suffered from pneumonia, so a family near the school volunteered to take him in. The school's janitor would find him at the end of the school day and carry him across the street.
