Can You Actually Have a Capybara as a Pet?
These giant guinea pigs are smart and social—so what could go wrong? Read on to better understand why capybaras don’t make good pets, and why they’re outlawed in several places.
Can capybaras be pets?
No—they should not be kept as pets. As Amy Haddock, assistant curator and registrar at the Association of Zoos & Aquariums, explains: “Capybaras should not be kept as pets.” State and local laws aside, capybaras are highly social animals that thrive only in herds. They require far more space, specialized habitat, and dietary support than any home environment can realistically provide. A solitary capybara in domestic settings would likely suffer physically and psychologically—and could pose real safety risks to people and other pets.
But is it legal to have a capybara as a pet?
Legality varies widely by location—and it’s rarely straightforward. You must check current wildlife and exotic-pet regulations at both the state and local levels, as rules often differ between jurisdictions.
- Some states—including Vermont, California, and Florida—require special permits to keep capybaras.
- Others, like Georgia and Alaska, ban them outright.
- Even where state law allows capybaras, cities or counties may prohibit them: for example, while permitted statewide in New York, capybaras are banned in New York City.
Do capybaras make good pets?
They do not. Here’s why:
Capybara behavior and temperament
Capybaras are crepuscular—most active at dawn and dusk—much like cats. Their Latin name translates to “water pig,” a fitting nickname given their love of aquatic environments. They spend hours cooling off and foraging in water and communicate with at least seven distinct vocalizations: guttural purrs, barks, clicks, squeaks, whistles, and grunts.
Where do capybaras live?
Native to South America, capybaras inhabit riverbanks, marshes, and other wetland areas. In captivity, they need companionship—ideally at least one other capybara—and an enclosure of no less than 312 square feet. That size must increase with herd size.
Crucially, their habitat requires both indoor and outdoor pools totaling at least 950 square feet. Capybaras can hold their breath underwater for up to five minutes—a natural defense against predators. Enclosures should also include natural substrates like mulch, sod, or river rock, plus nesting materials such as hay or straw.
What do capybaras eat?
In the wild, capybaras use their webbed feet to navigate wetlands and consume six to eight pounds of water plants and grasses daily. In captivity, they rely heavily on foraging but require a carefully balanced diet supplemented with high-fiber foods and vitamin C. According to Haddock, “An adult capybara should consume 2,500 calories per day.”
Capybara health
Diet is critical to their well-being. An unbalanced diet—especially one too high in sugars and carbohydrates and low in fiber—can lead to serious health problems, including:
- Tooth decay
- Overgrown teeth
- Obesity
- Type II diabetes
How much does a capybara cost?
A single capybara costs about $1,000—but remember, they must never live alone. Add in the expense of feeding a herd (several hundred dollars per month in food alone) and maintaining two constantly filtered pools (adding several hundred dollars monthly to your electric bill), and the true cost quickly becomes prohibitive.
How long do capybaras live?
In the wild, capybaras average four years. In accredited zoos with expert care, they typically live around 10 years.
Where can you interact with a capybara ethically?
Capybaras are wild animals—not domesticated pets—and their seemingly gentle demeanor belies sharp teeth and considerable strength. Petting one outside a professional setting is neither safe nor ethical.
Some accredited zoos—including the Brandywine Zoo—offer supervised, behind-the-scenes encounters that let visitors observe and learn about capybaras while maintaining safe, respectful boundaries.
You can also support capybaras through symbolic adoption programs. For instance, the Brandywine Zoo offers sponsorship opportunities for animals like Candance the capybara. These adoptions include certificates, educational fact sheets, and sometimes admission passes or membership benefits—depending on the level of support.
Smaller rodents that make great pets
While capybaras aren’t suitable as pets, many smaller, sociable rodents thrive in homes—including guinea pigs, hamsters, gerbils, and rats. If you’re drawn to their size and calm presence, consider adopting a large, affectionate dog instead.
Haddock emphasizes: “People should always consider adopting before purchasing any animal as a pet. There are foster homes even for guinea pigs.”
Commonly asked questions
Are capybaras domesticated?
No. Capybaras are wild, exotic animals—not domesticated species.
Are capybaras really rodents?
Yes—they’re the world’s largest rodents.
What is a group of capybaras called?
A herd.
Are capybaras herbivores?
Yes. They eat six to eight pounds of water plants and grasses daily, using their long incisors and webbed feet to forage.
Are capybaras nice?
While captive capybaras in zoo settings often appear docile, they remain wild animals with powerful jaws, sharp teeth, and unpredictable temperaments. Their size and strength mean even playful interaction can result in injury.
Can capybaras be potty-trained?
No. Capybaras cannot be house-trained. They are naturally messy, semi-aquatic animals whose needs extend far beyond what a home can accommodate.
Do capybaras bite?
Yes—and powerfully. As Haddock notes: “Capybaras have a very strong bite that could cause serious injury.”
Are capybaras endangered?
No. However, habitat loss and illegal poaching remain significant threats to wild populations.
