Capybara Care Guide
Hydrochoerus hydrochaeris
Capybaras are the world’s largest rodents and are native to South America. They are highly intelligent, social, semi-aquatic animals that require extensive space, access to water, and companionship. With proper care, pet capybaras typically live 8–12 years.
Capybaras should never be housed alone. They are herd animals that thrive in compatible pairs or small groups and can become stressed or develop behavioral problems if kept in isolation.
Before acquiring a capybara, owners should verify that ownership is legal in their state and municipality and that they have adequate space to house them appropriately.
Enclosure Setup/Design
Size:
- Outdoor housing is strongly recommended.
- A minimum enclosure of 250–400 square feet per capybara is recommended, though significantly larger areas are preferred.
- Secure fencing should be at least 4–5 feet tall and extend below ground for 1-2 feet to prevent digging escapes.
Essential enclosure features:
- Access to a large swimming pool or pond deep enough for full-body immersion
- Shaded areas
- Dry resting areas
- Grazing space
- Shelter from extreme weather
- Mud wallows or damp areas are beneficial
Indoor housing is generally not appropriate for adult capybaras.
Temperatures
Preferred:
- 60–85°F
- They can handle temperatures from 45°F up to 100°F if they have access to shelter, shade and water
Humidity/Water Provision
Preferred Humidity:
- 50–80%
Water:
- Fresh drinking water should always be available.
- Capybaras also require a clean swimming area that allows them to fully submerge their bodies. Water should be cleaned and changed regularly to reduce bacterial growth and a filtration system is recommended.
- The swimming area should be at least 3.5 feet deep and should include a ramp or gently sloping entry to allow easy access.
Diet
Capybaras are herbivores and must be fed a high-fiber diet. Capybaras cannot synthesize vitamin C and require daily dietary supplementation (1 gram per day).
Daily diet should include:
- Unlimited grass hay (Timothy, orchard, Bermuda, or meadow hay)
- Access to safe pasture grass for grazing.
- High-quality pellets fortified with vitamin C, ideally a commercial species-specific capybara diet such as Mazuri for approximately 25% of the diet (requirements may be higher in young growing animals or pregnant or nursing females)
- Fresh vegetables, leafy greens, and fruit
- Avoid excessive fruit and sugary foods.
- Fresh fruit and vegetables should make up less than 5% of the overall diet.
Example of safe greens and vegetables:
- Kale
- Bell peppers
- Carrots
- Green beans
- Broccoli
- Cucumbers
- Cabbage
- Endive
- Pumpkin
- Squash and zucchini
- Mustard greens, turnip greens, dandelion greens
- Various lettuces (green leaf, red leaf, romaine)
- Yams and sweet potato
Example of safe fruits:
- Oranges
- Pears
- Grapes
- Apples
- Bananas
- Melon
- Mangoes
- Peaches
- Plums
- Kiwi
Avoid:
- Bread
- Processed human foods
- Chocolate
- Onions
- Garlic
- Sugary treats
- Excess grain-based feeds
Enrichment
Capybaras are highly intelligent and require daily enrichment.
Provide:
- Swimming opportunities
- Grazing and browsing
- Digging areas
- Large logs and climbing structures
- Puzzle feeders
- Browse branches from safe tree species
- Social interaction with compatible capybaras
- Positive reinforcement training
Wellness/Preventive Care
- Annual wellness examinations are recommended.
- Routine fecal examinations are recommended.
- Dental evaluations should be performed regularly, as teeth grow continuously, and may require sedation or anesthesia for thorough oral examination and dental imaging.
- Spaying and neutering may be considered. Discuss the benefits and risks with your veterinarian.
- Microchipping is recommended for permanent identification.
Owners should monitor:
- Body weight
- Appetite
- Stool production
- Swimming behavior
- Skin and foot health
- Teeth
- Activity level
Common Problems/Diseases
Common health concerns include:
- Dental overgrowth
- Vitamin C deficiency / scurvy
- Obesity
- Foot injuries and pododermatitis
- Skin infections
- Gastrointestinal disease
- Internal and external parasites
- Heat stress
- Traumatic injuries
Contact your veterinarian immediately if your capybara experiences any of the following:
- Loss of appetite lasting more than 12–24 hours
- Difficulty breathing
- Persistent diarrhea
- Excessive drooling or difficulty chewing
- Rapid weight loss
- Lethargy or weakness
- Difficulty walking or swollen feet
- Large wounds or bleeding
- Signs of heat stress (panting, weakness, collapse)
Special Considerations
Capybaras have complex husbandry requirements and are best suited for experienced exotic animal owners with adequate outdoor space and access to veterinary care. Their need for social companionship, daily swimming opportunities, and a high-fiber diet supplemented with vitamin C makes them significantly more demanding to care for than most traditional companion mammals.
