What type of latrines should not be used for short bivouacs?

The correct answer is that a cat hole latrine should not be used for short bivouacs. Cat holes are shallow, temporary excavations used for waste disposal, typically in remote settings where no permanent facilities are available. They are most effective for individual use, and the process involves digging a shallow hole, using it, and then covering the waste with dirt.

However, for short bivouacs, where a group of individuals is present, using cat holes can become inefficient and pose sanitation risks. The areas can quickly become overcrowded, leading to potential contamination of the environment. Furthermore, the necessity for repeated digging of new holes can lead to increased soil disruption and the challenge of properly covering waste.

In contrast, other latrine types, like fill latrines and deep pit latrines, are designed for handling waste more effectively over a short duration, allowing for better sanitation management in a compact setting. Burn out latrines can also be used but are less common and specific in application. Thus, for a short bivouac, implementing a cat hole latrine compromises sanitation and poses health risks, underscoring why it is not the suitable choice.
