Guinea pigs (Cavia porcellus) have a rich history dating back thousands of years. They were first domesticated around 5000 BC in the Andean Highlands of South America where they were primarily kept as a food source. Archaeological evidence such as statues and art from ancient Peru highlights their significance in early cultures. Introduced to Western societies in the 16th century by European traders, guinea pigs quickly became popular pets. Today, over half a million UK households cherish them as gentle companions. To find reputable breeders, consider exploring guinea pig breeders who prioritise ethical care and responsible pet ownership.
Despite their name, guinea pigs are neither pigs nor from Guinea. Their native home is the Andes Mountains in South America. The term "guinea" might stem from the animal's exotic origin or trade routes through Guinea or Guiana. They're actually rodents, closely related to the Capybara, the largest rodent species. The "pig" nickname comes from their stout build and pig-like noises they often make. They are sometimes affectionately called "cavies," derived from their Latin name.
Guinea pigs are surprisingly vocal animals with a rich variety of sounds signalling different emotions and social cues. Common vocalisations include:
Understanding these vocal signals strengthens your bond and helps ensure their well-being.
Unlike many animals, guinea pigs cannot produce their own vitamin C, an essential nutrient for preventing scurvy, a potentially fatal condition. Symptoms include lethargy, swollen joints, rough coat, loss of appetite, and slow wound healing. A varied diet rich in vitamin C is crucial, including fresh vegetables like kale, peppers, broccoli, spinach, and small amounts of fruit such as orange slices. Caution is necessary to avoid overfeeding vitamin C, which can cause diarrhoea. Freshness and variety ensure your pet's health.
Guinea pig pups are born precocial—meaning they arrive fully furred with open eyes and are able to run within hours of birth. They have teeth at birth and can nibble solid food while still nursing. By about five days old, pups can live quite independently. This maturity at birth contrasts with altricial species like rabbits, whose young are born helpless and blind. This fascinating trait supports their survival in the wild and influences their care as pets.
Guinea pigs are sociable animals who thrive in company. Living in groups reduces stress and promotes natural behaviours such as grooming, socialising, and communication. Females usually coexist well, while neutered males (boars) can integrate peacefully. Housing guinea pigs with other species such as rabbits is generally discouraged due to differing needs and risks of injury or illness. Providing companionship with fellow cavies encourages a relaxed and happier pet.
These small rodents are surprisingly intelligent. They remember complex paths to food, can learn simple tricks like ringing bells or navigating obstacle courses, and may respond to their names. Although not as agile as some pets, guinea pigs can jump small barriers and are curious explorers. Enriching their environment with toys, treat puzzles, and varied spaces helps keep their minds active and reduces boredom.
In an extraordinary chapter of history, guinea pigs were among the first animals sent into space. On 9 March 1961, a guinea pig orbited the Earth aboard Sputnik 9, accompanied by other small animals. They returned safely, contributing valuable information to space biology studies. This remarkable feat reflects guinea pigs' adaptability and resilience, traits that endear them even more to pet owners.
Keeping your guinea pig stimulated is key to their happiness and health. Here are some enjoyable activities to consider:
Rotate toys regularly and supervise playtime to ensure safety.

Regular veterinary checks and a clean, enriched environment contribute to a long, happy life.
Quick Answer: In the UK, the typical cost of a guinea pig ranges from £20 to £40, depending on breed, age and source. Additional expenses include housing, food, healthcare and enrichment supplies.
Guinea pigs are affordable pets for many families, but initial costs go beyond the purchase price. Choosing pets from reputable breeders ensures good health and ethical practices. You'll also want to budget for a suitable hutch or enclosure, daily fresh food (including vitamin C rich veggies), hay, bedding, and regular check-ups at the vet. Annual insurance or emergency funds are recommended to cover unexpected medical costs. Investing time and money in proper care promotes your guinea pig's wellbeing and a rewarding companionship.
Guinea pigs are fascinating, sociable, and intelligent pets with a captivating history and unique care needs. Understanding their special anatomy, dietary requirements, and social behaviour enriches your relationship and helps ensure a healthy life for your furry friend. For those looking to welcome guinea pigs into their homes, always seek out responsible breeders or consider adoption options. Enrich their daily lives with games and companionship to keep them happy and thriving in 2025 and beyond.
