Capybaras (Hydrochoerus hydrochaeris) are the world’s largest rodents, native to South America’s wetlands and known for their incredibly relaxed demeanor. They can reach up to 4.4 feet in length and weigh between 77 to 150 pounds, living around 8 to 12 years in captivity. These gentle herbivores thrive on a diet of grasses, aquatic plants, fruits, and bark, and they even practice coprophagy—eating their own feces to maximize nutrient absorption. Social by nature, capybaras prefer group living and can become stressed or lonely in isolation. Their natural habitat includes access to water for swimming and staying cool, which is vital when designing enclosures for pet capybaras; such spaces should offer at least 400 square feet per animal, with secure fencing, shelter, and shaded areas. With proper grooming, vet care, and companionship, these creatures are affectionate and adaptive—often getting along with other animals like dogs or cats. Despite their popularity, ownership laws vary, so legal and ethical research is essential. Capybaras communicate through purrs, barks, and whistles, and in some places like Japan, they’re pampered with hot spring baths that they seem to love. They’re a fascinating blend of chill vibes and unique care requirements—perfect for admiration or dedicated guardianship.
