The '''common degu''' ('''''Octodon degus'''''; {{IPAc-en|ˈ|d|eɪ|ɡ|uː}}), or, historically, the '''degu''', is a small [[hystricomorpha]] [[rodent]] [[endemic]] to the [[Chilean matorral]] [[ecoregion]] of [[central Chile]].<ref>C. Michael Hogan & World Wildlife Fund. 2013. Chilean Matorral. Ed. Mark McGinley. Encyclopedia of Earth. National Council for Science and the Environment. Washington DC</ref> The name ''degu'' on its own indicates either the entire genus ''[[Octodon]]'' or, more commonly, just the common degu. Common degus belong to the [[parvorder]] [[Caviomorpha]] of the [[infraorder]] [[Hystricognathi]], along with the [[chinchilla]] and [[guinea pig]]. The word ''degu'' comes from the indigenous language of Chile, [[Mapudungun]], and the word ''dewü'', meaning 'mouse' or 'rat'.<ref>{{Citation |title=Diccionario Mapuche: Mapudungun/Español, Español/Mapudungun |language=es |edition=2nd |year=2006 |editor=Muñoz Urrutia, Rafael |location=Santiago, Chile |isbn=978-956-8287-99-3 |pages=104, 105, 141 |publisher=Editorial Centro Gráfico}}</ref>

The animal may be kept as a domestic pet, though there are prohibitions on their ownership in some territories. As a pet, the animal is larger than a [[golden hamster]] but smaller than a [[fancy rat]].

== Description ==
The common degu is a small animal with a body length of {{convert|25.0|to(-)|31.0|cm|in|abbr=on}} and a weight of {{convert|170|to|400|g|oz|abbr=on}}. It has yellow-brown fur above and creamy-yellow below, with yellow around the eyes and a paler band around the neck. It has a long, thin tail with a tufted, black tip, dark sparsely furred ears, and pale grey toes. Its fifth toe is small with a nail, rather than a claw, on the fore feet. Its hind feet are bristled. Its cheek teeth are shaped like figures-of-eight, hence the degu's [[genus]] name ''Octodon''.<ref name="Woods1975"/>

== Social behavior ==

Common degus are highly social. They live in burrows, and, by digging communally, they are able to construct larger and more elaborate burrows than they could on their own.<ref>{{Citation|last1=Ebensperger| first1=L.

Common degus have an intolerance of dietary sugar. They have been found to have a divergent [[insulin]] structure (one of the hormones that regulate [[blood glucose level]]) and so are highly susceptible to developing [[diabetes mellitus]] when fed regularly on a diet containing free sugars.<ref>{{cite journal |last1=Opazo |first1=J.C. |last2=Soto-Gamboa |first2=M. |last3=Bozinovic |first3=F. |year=2004 |title=Blood glucose concentration in caviomorph rodents |journal=Comp.

Common degus are research subjects due to their relationship with sugar and diabetes, but are also studied for a variety of other reasons.
[[Neuroscientist]]s at the [[RIKEN|Riken Institute]] in [[Tokyo]], [[Japan]], used common degus for research into tool use in animals with good eye-and-paw coordination, in which they spontaneously learned to use a tiny rake to retrieve out-of-reach seeds.<ref name="Okanoya 2008 e1860"/> Common degus have also been found to spontaneously stack objects in order of decreasing size.

Another area of common degu research is [[circadian rhythm]] function, i.e., the ability of the brain to tell what time of day it is.

==As pets==

[[File:Degus-4er-Bande.jpg|thumb|Captive common degus need plenty of space to exhibit a full range of normal behaviours]]
[[File:Common degu in a cage - 2023 March 7.webm|thumb|A degu in a cage, 2023]]

After initial interest into common degus as [[Animal research|research subjects]], they have become popular as [[pet]]s. Their advantages over traditional small pets are their [[Diurnality|diurnal]] habits, bubbly personalities, the haired tail (as compared to [[rat]]s and [[mouse|mice]]) and their lifespan: they are reported to live up to 13 years under ideal circumstances (though a poor gene pool or genetic background often reduces a pet degu's lifespan significantly).{{citation needed|date=November 2011}} The average lifespan of a common degu in captivity is typically around six to eight years of age.

One disadvantage of the common degu as a pet is their predisposition to chewing, due to their continually growing incisor and molar teeth.<ref name=Woods1975/> For this reason, common degus cannot be housed in plastic-bottomed cages typically found in pet stores. Lining the floors of a degu enclosure with grass mats or a soft fabric prevents infections known as [[Bumblefoot (infection)|bumblefoot]].{{citation needed|date=December 2010}}

Untamed common degus, as with some other small animals kept as pets, can be prone to biting, but their intelligence makes them easy to tame. Regular non-predatory handling and food offerings help with this transition. The common degu's tail skin and tuft is easily "shed" (pulled off). This helps common degus in the wild elude capture by predators, but it is painful to the creature and the tail end will not grow back, and as such pulling on it or picking up a degu by the tail is not recommended. When tail shedding occurs, common degus will chew off the damaged portion. This can reduce the chances of infection.{{citation needed|date=April 2018}}

Common degus often "groom" their human owners with a gentle nibbling action, and will bond with people that spend time with them. Common degus need regular [[Sand bathing|sand baths]], like [[Chinchilla]]s need dust baths, to keep their coats healthy and free from grease. They should have access to these baths regularly, preferably two or three times a week for half an hour at a time.
