The Mansion

The Mansion is the main setting of Cat in the Box. Girl visits the Mansion following the sudden disappearance of the resident cult a few months prior to the events of the game. Once inside the Mansion, it is impossible to leave the premises until after the Ritual has been completed.

Description
The Mansion consists of many rooms, including two basement levels, a second floor, and an attic. Outside is a large courtyard and an unfenced cliff to the south. Once inside the Mansion, there is a short period of time in which Girl can go back outside, but afterwards the Mansion will change and the exit will be replaced with another room. Looking outside through a window after the change reveals only pure darkness.

Trivia

 * There is a hidden toilet area that can be found via unscrewing a panel in the room east of the prison. The panel can be found on the wall in front of the partition screen. Entering the toilet area triggers the Toilet achievement.
 * When Girl enters the Mansion, she states that it is 12:07am. All clocks in the Mansion read 12:02.
 * Upon entering the Mansion, Girl will remark about the lights being on despite them appearing to be off from the outside.
 * There is a photograph of people behind a ribbon in front of the Mansion in the Cult Leader's office labeled "Completion Ceremony. March 15". This is notably the Ides of March.
 * The starting area of the game has a chance of having a varying number of missing persons posters. Girl's scooter can spawn in multiple different spots as well.
 * Upon discovering the room with the hospital beds, Girl remarks that the Cult Leader seems to have been a doctor and treated his patients in the Mansion.
