Common degus start breeding in autumn in the Chilean climate. As they are seasonal breeders, they prefer to mate when the day length is the same as the night. The females stay in the burrows during the gestation length of 90 days.

The common degu pups are born around mid-spring. The gestation length of 90 days also varies according to the litter size in common degus. According to the recent breeding status, one female common degu gives birth to an average of six pups.

The females are usually responsible for searching for food. They roam around in groups to forage while the males stay inside and keep the pups warm. The precocial pups are born with complete development and darker small fur over their bodies.

Males and females both protect the young ones until they can leave outside. The common degu pups have active auditory and visual systems. The diurnal behavior of common degus enables them to have good and clear night vision.

Common Degus as Pocket Pets

Common degus can live up to 8 years and are very good with kids. I recommend you to get a young degu as it is easier to tame and interact with. Staying playful is a very important aspect of a common degu’s life.

They are also highly curious animals and try to explore everything around them. It is always ideal to get two or more degus because of the communal nature. If you want your cage to get filled with young degus, you can choose similar gender degus in one cage.

Keeping common degus engaged in physical activities is good for their mental health. There are many common degu-friendly toys available in the market. Chewing toys are one of them as all rodents need to maintain their oral health in good condition.

Like other pocket pets, common degus are also pretty sensitive to many stressful factors. It is advisable to keep them away from loud noises and movements. You can also observe through their screaming voices that your common degu is experiencing stress.

Because of their invasive nature, many states across the US prohibit their use as pets. This is because they populate themselves easily in a new ecosystem and damage it. The prohibition is functional in Utah, California, Alaska & Georgia.

Diet Requirements for Common Degus

In the wild, common degus prefer to stay on an herbivorous diet. Their stomach cannot tolerate anything other than natural grasses and plants. This strictly herbivorous nature enables them to browse and eat shrub leaves and seeds.

In the Chilean environment, forage is dry for almost the whole year. The forage available is usually dry and therefore, common degus eat a high-fiber diet. You can find more regarding the diet of common degus through our Degus diet guide.

Degus are active during the day and emerge out of burrows during the morning and evenings. Most of them don’t prefer to leave their burrows mid-day due to increased predator activity. These aspects enable them to survive in the wild.

As pets, common degus must stay on a high-fiber diet. Animal nutritionists suggest completely cutting off the sugars from degu’s diet. Their digestive system cannot tolerate high carbs and sugars and it also leads to several other health issues.

The digestive and hormonal physiology of common degu is incompatible with sugars. Research has found the divergent insulin structure in the case of common degus. This makes them easily prone to issues such as diabetes mellitus.

The basic diet of common degu consists of freshly dried hay as the main diet part. Make sure to get only the highest quality hay. It is vital to check for the presence of harmful pesticides and insecticide chemicals which are lethal to degus.

There are many commercially available pellets foods made according to rodent nutrition. The nutritional composition of such foods contains minimal carbs and low protein. Besides, these pellets still contain more than 15% fiber in them.

Common degus also need other essential amino acids and fatty acids. You can fulfill this requirement by adding herbs and vegetables to your diet. However, not every vegetable is suitable for common degus.

A good choice is leafy vegetables such as lettuce and celery. Mint and parsley are good herb choices for them as these create minimal stomach upset and bloating in degus. Nevertheless, the use of vegetables is restricted to one or two times per week.

Housing Requirements for Common Degu

Wild common degus have their natural habitat in the form of burrows. These burrows protect them in case of danger and also keep the young ones warm. However, they are highly adaptable to new environmental setups as pets.

The goal of housing for common degu focuses on the provision of a stress-free ideal place. Keeping them in an unhygienic environment leads to health deterioration. It will not only affect them physically but lead to stress and anxiety.

If you’re a beginner and confused regarding housing, have a read about the degu cage setup guide. Common degus can easily live in captive environments when all of the housing needs are fulfilled.

This includes choosing a cage of an appropriate size and material. Degus have the inherent ability to chew onto stuff. Use a wired mesh metal cage so they can’t escape after chewing on one side.

In the case of cage size, the general rule is to provide 4000 square centimeters of space per degu. Common degus are playful so providing them enough space saves you from panic troubles. You can also place the males and females in separate cages to avoid breeding.

Among many different cage materials, only glass and metal are ideal for common degus. They have very fast movements and it is not easy to catch them once they escape. Besides, chewing on plastic and other material cages causes health issues in common degus.

One of the important parts of housing is the provision of degu-friendly toys. You can also make small hideouts for them to feel safe and for sleeping. The food bowls must be made of metal to avoid them from gnawing on them.

Similarly, glass water bottles are an ideal choice. Chinchillas and common degus have similar toys and living needs. A good option is to tie a hammock inside for a comfortable place to sit and relax.

As physical activity is very important, an exercise wheel can do this job quite well. In choosing so, stick to the same rule of only metal or glass material for it. There are many exercise wheels available but the use of treadmills is discouraged.

Chewing toys such as wooden blocks of bamboo and applewood is ideal. Such wooden snacks can help fulfill the chewing needs of common degus. Cardboard and wooden chew sticks clean their teeth and help to rasp them while gnawing on these toys.

Apart from that, the cage location, its placement, and regulation of temperature must be maintained. If you’re interested or trying to develop a cage setup, I encourage you must give read to the guide for degu cage setup.
