Animal latrine

Animal latrines (latrine areas,

urinate. Many kinds of animals are highly specific in this respect and have stereotyped routines, including approach and departure.[2]
Many of them have communal, i.e., shared, latrines.

Animals with dedicated defecation sites

Animals with communal latrines include

Eurasian badgers,[3] elephants,[4] deer,[5] antelopes,[6] horses,[1] and (prehistorically) dicynodonts (a 240-million-year-old site was called the "world's oldest public toilet").[4]

A regularly used toilet area or

dunghill, created by many mammals, such as hyraxes or moles, is also called a midden.[7][8]

Some

use dedicated defecation sites.

European rabbits may deposit their pellets both randomly over the range and at communal latrine sites.[11]

Function and impact

Territoriality

Middens and other types of defecation sites may serve as

stallions,[1] and deer bucks,[5] which are thought to serve for confrontation avoidance. In contrast, female and young animals exhibit no such behavior.[1]

Sanitation

Dedicated defecation sites are thought to be the result of sanitation-driven behavior. For example, the spider mite Stigmaeopsis miscanthi constructs woven nests, and nest members defecate at only one site inside the nest.[12] Dedicated latrine areas observed by free-roaming horses mean that grazing area is kept parasite-free. Even stabled horses seem to have vestiges of such behavior.[1]

Herbivoral livestock is at risk of parasite/pathogen exposure from feces during grazing, therefore there is an interest in research of livestock behavior in the presence of feces both of their own species, and others, including wildlife, including the dependence on defecation patterns.[13]

Ecological impact

Latrines of herbivores, such as antelopes, play an important role in ecology by providing enrichment of certain areas in nutrients. It is described that duiker and steenbok antelopes tended to defecate in exposed sites, generally on very sandy soil, while klipspringer preferred rocky outcrops, thus enriching the nutrient-deficient areas, as well as depositing plant seed there.[6]

Raccoon latrines

A common nuisance of raccoons is raccoon latrines (raccoon toilets), which may contain eggs of the roundworm Baylisascaris procyonis. Nuisance raccoon latrines may be found in attics, on flat roofs, on logs, in yards and sandboxes, etc.[14][15][16]

Use in research

In addition to immediate research of animal behavior and biology, animal toilets and

climate research, and other areas. They provide various information: plant habitats, historical information about prehistoric life and climate, etc.[4][17]

Animal latrine associates

Some

There is a curious association of Cucumis humifructus ("aardvark cucumber" or "aardvark pumpkin") with latrines of aardvarks. C. humifructus produces its fruit underground, the aardvark burrows for them, and then deposits its seeds in dunghills near its habitat. The distribution of C. humifructus tends to match that of aardvark latrines.[19]

Some insects (e.g.,

excrement
and hence are natural associates of dung sites.
