Mammalian Degu Overview
The Mammalian Degu (Octodon degus) is a small, social rodent native to central Chile. Often called the “Chilean squirrel,” degus are prized for their intelligence, curiosity, and diurnal nature, making them engaging pets. This comprehensive guide covers all aspects of degu ownership, from history to daily care.
History and Origin
Degus originate from the rocky foothills and scrublands of central Chile, where they live in communal burrows. First described by naturalist John Edward Gray in 1847, they were initially studied for their complex social structures and vocalizations. In the wild, degus are herbivorous and active during daylight hours. They were introduced to the pet trade in the 20th century and have since gained popularity as pocket pets worldwide.
Appearance and Physical Features
Size and Weight
- Length: 25–31 cm (including tail, which is 10–15 cm)
- Weight: 170–300 grams (males slightly larger than females)
Coat and Colors
Degus have coarse, dense fur. The most common color is agouti (brown-gray with a cream belly), but selective breeding has produced blue, black, and sandy variations. Their tails are tufted at the tip.
Distinctive Features
- Yellow-orange incisors: A unique trait among rodents.
- Large, dark eyes and rounded ears.
- Five toes on hind feet and four on front, with strong claws for digging.
- Degloving tail: The tail skin can detach if grabbed (a defense mechanism).
Personality and Behavior
Degus are highly social, curious, and active. They communicate with a range of vocalizations and scent marking. Key traits:
- Diurnal: Active during the day, making them suitable for human schedules.
- Intelligent: Can learn tricks, solve puzzles, and recognize owners.
- Social: Thrive in same-sex pairs or groups; solitary degus can become depressed.
- Chewers: Incisors grow continuously, requiring constant chewing to wear them down.
- Explorers: Need enrichment like tunnels, wheels, and hiding spots.
Suitable For
Families with Children
Degus can be good pets for older children (10+) who understand gentle handling. They are fragile and may bite if frightened. Supervised interaction is essential.
Apartment Living
Degus are quiet and produce minimal odor if cleaned regularly. A spacious cage with bedding and exercise wheel fits well in apartments. However, they need daily out-of-cage time in a secure, degu-proofed area.
First-time Pet Owners
Degus require specific care (diet, housing, enrichment), which may be challenging for beginners. They live 6–8 years, so commitment is needed. Research and preparation are advised.
Exercise and Mental Stimulation
Degus are active and need both physical and mental exercise.
- Exercise: A large solid-surface wheel (12+ inches diameter) and daily free-roam time in a safe space.
- Mental stimulation: Puzzle feeders, tunnels, branches to chew, and foraging toys. Rotate toys to prevent boredom.
- Social interaction: Spend time daily talking, hand-feeding, and handling.
Grooming and Coat Care
Degus groom themselves efficiently. Care tips:
- Brushing: Not necessary; they shed lightly.
- Bathing: Never water-bathe; provide a chinchilla-style dust bath (special volcanic ash) 2–3 times per week for 15–20 minutes.
- Nail trimming: Every 4–6 weeks if overgrown.
- Dental check: Provide chew sticks (apple, willow) to maintain tooth health.
