Capybaras (Hydrochoerus hydrochaeris) are the world’s largest rodents, closely related to guinea pigs. They are highly social, semi-aquatic animals that require specialized care to thrive in captivity.
Space: Provide a large, secure outdoor enclosure — ideally at least 12x20 ft per pair. Capybaras need room to graze, run, and interact.
Water Access: A swimming pool or pond is essential. Water should be deep enough for full immersion and long enough for swimming.
Shelter: Provide a dry, shaded area and protection from extreme weather.
Substrate: Grass or soil is preferred; avoid wire or concrete flooring that can injure feet.
Fencing: Secure fencing 4 ft or higher; capybaras can push through weak barriers.
Capybaras are herd animals and do best in pairs or small groups. Keeping a single capybara is not recommended, as isolation can lead to stress and behavioral problems.
Capybaras are strict herbivores with hindgut fermentation, similar to horses and guinea pigs.
Primary Diet: Unlimited access to grass hay(timothy, orchard).
Grazing: Access to pesticide-free grass pasture whenever possible.
Pellets: Guinea pig or rabbit timothy-based pellets (vitamin C-fortified).
Fresh Produce: Offer leafy greens (romaine, dandelion, collard, endive) daily. Avoid excessive fruit or sugary foods.
Vitamin C: Capybaras cannot synthesize vitamin C— supplement daily to prevent scurvy (25–50 mg/kg/day).
Fresh Water: Provide constant access to clean drinking water.
Annual Wellness Exam: Physical exam, fecal parasite check, bloodwork as needed.
Vaccinations: Some facilities vaccinate against rabies and clostridial diseases — ask your veterinarian for recommendations.
Parasite Control: Regular fecal monitoring and deworming if needed.
Dental Care: Monitor continuously growing incisors — overgrowth may require trimming.
Highly intelligent and trainable — can learn to come when called and use litter areas.
Provide safe chew items (hardwood branches) to prevent boredom and support dental health.
Offer a variety of enrichment: wading areas, digging spots, and safe toys.
Vitamin C deficiency (scurvy): Lameness, joint swelling, poor coat, anorexia
Obesity: From overfeeding or lack of exercise
Dental problems: Malocclusion, overgrown incisors
Skin issues: Mange mites, fungal infections
Pododermatitis: From wet or rough flooring
Capybaras can be gentle but are large and strong — always supervise children.
Socialize early to make veterinary care and handling easier.
Use positive reinforcement and low-stress handling techniques.
Regulations vary by state and municipality. Check local laws before acquiring a capybara — some areas require special permits.
Routine exams and proper diet/husbandry can prevent the most common health problems. Early intervention is key when issues arise.
