Degu — Newborn & Baby Care

Degu pups are born in a remarkably advanced state compared to many other small rodents. They arrive fully furred with their eyes open, and they can move around the nest within hours of birth. A typical litter consists of four to eight pups, though litters as small as one or as large as twelve have been documented. Despite their relatively mature appearance at birth, these tiny animals still depend entirely on their mother for warmth, nutrition, and protection during the critical first day.

During the first twenty-four hours, the mother will clean each pup thoroughly, stimulating circulation and breathing. She will also consume the placenta, which provides her with essential nutrients after the exertion of labor. It is important not to disturb the nest during this time, as unnecessary handling can cause stress that may lead the mother to reject or neglect her pups. Keep the cage in a quiet area away from household traffic, loud noises, and other pets.

Observe the litter from a distance to confirm that all pups appear active and are clustering near the mother. Pups that are consistently pushed away from the group or that appear lethargic and cold may need intervention. Ensure the ambient temperature around the cage remains stable, ideally between 68 and 72 degrees Fahrenheit, since newborn degus cannot yet regulate their own body temperature effectively.

Make sure the mother has access to fresh water and high-quality food at all times. She will need additional calories and hydration to support milk production. A shallow water dish placed near the nest can help her stay hydrated without having to leave her pups for extended periods. Avoid rearranging the cage or adding new accessories during this sensitive window.

Degu pups begin nursing almost immediately after birth, and the mother's milk provides all of the nutrition they need during the first two to three weeks of life. The milk is rich in protein and fat, supporting the rapid growth that occurs during the neonatal period. Pups will nurse frequently throughout the day and night, and you may notice them latching on even while the mother moves around the cage.

Because degus are highly social animals, communal nursing is not uncommon if multiple females share a cage. Females within a bonded group may take turns nursing and watching over pups, a behavior that mirrors their cooperative care strategies in the wild. If you have a single mother, ensure she is well-nourished with a diet that includes quality hay, a small amount of pellets formulated for degus or chinchillas, and occasional fresh vegetables that are low in sugar.

By the end of the first week, pups will begin to show interest in solid food, nibbling at hay and pellets near the nest. This early exploration is normal and should be encouraged by making soft hay and finely ground pellets accessible at floor level. Do not offer fruits, sugary treats, or high-starch vegetables, as degus are extremely susceptible to diabetes and metabolic issues even from a very young age.

Weaning typically begins around three to four weeks of age and is usually complete by six weeks. During the transition, pups will continue to nurse intermittently while increasing their intake of solid food. Monitor each pup's weight to confirm steady gains. If any pup appears significantly smaller than its littermates or seems unable to compete for nursing access, consult an exotics veterinarian for guidance on supplemental feeding options.

Degu pups develop rapidly compared to many rodent species. Within the first few days of life, they are already exploring the area immediately around the nest, testing their legs and beginning to interact with their littermates. Their coordination improves noticeably by the end of the first week, and they start attempting short climbing and jumping maneuvers inside the cage.

By the second week, pups become increasingly bold and curious. They will venture farther from the nest, sample solid foods, and begin grooming themselves and each other. Social play becomes a prominent behavior, with pups chasing, wrestling, and piling on top of one another. These interactions are not just entertaining to watch—they are essential for developing the social skills that degus rely on throughout their lives.

Around three weeks of age, pups begin to resemble miniature adults in both appearance and behavior. They are fully mobile, can eat solid food independently, and engage in dust bathing if provided with a suitable bath. Their teeth are well-developed, and they will chew on hay, wooden toys, and cage accessories with increasing enthusiasm. Hearing and vision are fully mature at this stage.

Between four and six weeks, the transition from dependent pup to independent juvenile is largely complete. Pups can thermoregulate on their own, feed themselves entirely, and navigate complex cage environments with confidence. This is also the period when sex determination becomes more reliable, and separating males from females is critical to prevent early, unplanned breeding.

Maintaining a stable and comfortable environment is essential for newborn degu survival. Although degu pups are born furred, their small body mass means they lose heat quickly and are vulnerable to temperature fluctuations. The cage should be kept in a room where the temperature stays consistently between 65 and 75 degrees Fahrenheit, with no drafts from windows, doors, or air conditioning vents.

The nesting area itself should be well-insulated. Provide the mother with plenty of nesting material such as shredded paper, unscented tissue, or soft hay so she can build a warm, enclosed nest. Avoid cotton or fabric-based nesting materials, as fibers can wrap around tiny limbs and cause circulation problems. The nest box should have a single entrance that the mother can easily defend while keeping the interior dark and sheltered.

Humidity is another factor to monitor, particularly in dry climates or during winter when indoor heating can drop humidity levels significantly. Aim for a relative humidity between 40 and 60 percent. Excessively dry air can cause skin irritation and respiratory discomfort for both the mother and her pups, while overly humid conditions can promote fungal growth in bedding.

Keep the cage clean but avoid deep-cleaning the nest area during the first two weeks. Spot-clean soiled bedding at the edges of the cage and replace food and water daily, but leave the nest itself undisturbed. The familiar scent of the nest helps the mother remain calm and attentive, and disrupting it can trigger anxiety that may affect her nursing behavior.

Degus are among the most social of all rodent species, and the foundations of their social behavior are established in the earliest days of life. Pups that grow up in a well-bonded group learn essential communication skills, including vocalizations, grooming rituals, and the body language cues that govern degu social hierarchies. Depriving pups of adequate social interaction during the neonatal period can lead to behavioral problems that persist into adulthood.

Gentle human handling can begin around the end of the first week, though sessions should be brief and calm. Pick up each pup carefully, supporting its entire body, and hold it close to your body for warmth. Speak softly and avoid sudden movements. These short handling sessions, lasting just a minute or two each day, help pups become accustomed to human scent and touch, making them more confident and easier to handle as they grow.

Allow the mother and any companion females to remain present during handling sessions whenever possible. Degus take cues from the behavior of their group members, and a calm mother signals to her pups that there is no danger. If the mother shows signs of distress—rapid vocalizing, attempting to bite, or frantically running around the cage—return the pups immediately and try again later.

As pups become more mobile during weeks two and three, they will naturally begin interacting with any other adult degus in the cage. These interactions teach conflict resolution, food-sharing etiquette, and communal sleeping habits. Observing these behaviors gives you valuable insight into each pup's emerging personality, helping you identify which individuals may need extra socialization support.

Finding an exotics veterinarian who is experienced with degus should be a priority well before any pups are born. Degus have unique health needs that general small-animal veterinarians may not be familiar with, particularly their susceptibility to diabetes, dental disease, and cataracts. Establishing a relationship with a knowledgeable vet ensures that you have expert guidance available if complications arise during or after birth.

A veterinary checkup for the litter is recommended at approximately two weeks of age, or sooner if any pup shows signs of illness or failure to thrive. During this visit, the vet will assess each pup's weight, hydration, fur condition, and overall development. They will also check for congenital issues such as dental malocclusion, which can become a serious problem if left unaddressed in this species.

At home, weigh each pup daily using a small digital scale. Consistent weight gain is the single best indicator of healthy development. A pup that plateaus or loses weight over two or more consecutive days warrants immediate veterinary attention. Keep a simple log recording each pup's weight, along with any observations about its behavior, appetite, and activity level.

Watch for signs of respiratory infection, which can spread rapidly through a litter. Symptoms include audible wheezing, nasal discharge, lethargy, and labored breathing. Diarrhea is another red flag that may indicate dietary issues, bacterial infection, or parasites. Prompt treatment is critical for neonatal degus, as their small size means they can deteriorate quickly without intervention.

While most degu births and neonatal periods proceed without incident, knowing when to seek help can mean the difference between a minor setback and a serious emergency. One of the most urgent situations is when a pup is rejected by the mother. A rejected pup will be found consistently away from the nest, often cold and lethargic. If warming the pup and returning it to the nest does not result in the mother accepting it, hand-rearing may be necessary under veterinary guidance.

Prolonged labor or complications during delivery require immediate veterinary attention. If the mother has been actively straining for more than an hour without producing a pup, or if she appears exhausted and has stopped pushing despite an obviously distended abdomen, contact your exotics vet or an emergency animal hospital right away. Dystocia is less common in degus than in some other rodents but can be life-threatening when it occurs.

Monitor the litter for any pup that is significantly smaller than its siblings and failing to gain weight despite access to the mother. Runting can occur for various reasons, including congenital defects, inability to compete for nursing, or internal health problems. These pups may benefit from supplemental feeding with a small syringe and a milk replacer recommended by your vet.

Behavioral changes in the mother should also raise concern. If she becomes unusually aggressive, stops eating, or shows signs of pain such as hunching, tooth grinding, or reluctance to move, she may be experiencing postpartum complications including infection or retained placenta. A mother who is unwell cannot adequately care for her litter, so addressing her health is essential for the survival of the pups as well.
