A cathole or cat hole is a pit for human feces. Catholes are frequently used for the purpose of disposing of bowel movements or waste water (such as the water from cleaning the kitchen dishes) by hikers and others engaging in outdoor recreation.
Catholes must be located at a reasonable distance (at least 60 m) from water sources (rivers, lakes, etc.), to avoid possible bacterial contamination of water via precipitation, as well as away from trails. It is recommended to avoid concentration of catholes around campsites. Filled catholes must be covered with a reasonably thick layer of soil, to prevent access by animals, some of which are coprophagous.
