Profile description
The Peruvian Guinea Pig is a domesticated guinea pig variety (Cavia porcellus). It is a long-haired cavy with coat growing forward and over the head. Its recognised appearance includes very long dense hair that may trail along the ground. The variety is usually calm but dependent on intensive grooming. Expected lifespan with appropriate husbandry is approximately 5-8 years, although genetics, desexing, diet, housing, infectious disease exposure and access to an experienced veterinarian can alter longevity substantially. Individual Peruvian Guinea Pig animals still vary with breeding, early handling, health and previous housing, so variety traits do not predict every temperament.
The Peruvian Guinea Pig is a domestic breed or variety, but selected size, ear or coat traits do not change the species' core behavioural and nutritional needs. Choose a Peruvian Guinea Pig from an ethical captive-bred source that provides health and husbandry information and avoids exaggerated features that compromise function. Temperament still varies between individual Peruvian Guinea Pig animals. Guinea pigs are small prey animals and may hide pain until illness is advanced, so calm handling, predictable routines and opportunities for normal species behaviour matter. Children need close supervision, with an adult responsible for feeding, cleaning, veterinary care and legal obligations.
The main variety-specific considerations are these: long hair increases matting, urine scald, hidden skin lesions, heat stress and flystrike risk. Pet coats are commonly trimmed for welfare.
Domestic guinea pigs are generally lawful across Australian states and territories, subject to council, tenancy, containment and animal-welfare rules. Council limits, rental conditions, movement controls, biosecurity orders and welfare codes may affect Peruvian Guinea Pig ownership, so current legality must be confirmed before purchase or relocation.

Practical preparation for welcoming this guinea pig into your care.
Care requirements
Peruvian Guinea Pig nutrition is one of the most important parts of daily care. Feed the Peruvian Guinea Pig unlimited grass hay, a measured guinea-pig pellet and fresh vegetables providing reliable vitamin C. Vitamin C deteriorates in stored food and water, so water additives alone are not dependable. Avoid abrupt changes, high-sugar treats and unrestricted pellets that reduce hay intake. A sudden reduction in the Peruvian Guinea Pig's appetite is an emergency because intestinal motility and general condition can deteriorate rapidly.
Peruvian Guinea Pig housing must support normal movement, comfort and safety. Use a spacious solid-floored enclosure with soft absorbent bedding, multiple hides, good ventilation and a stable temperature. The Peruvian Guinea Pig tolerates cold poorly when wet and heat poorly above the mid-twenties. Outdoor housing must protect against predators, insects, rain and rapid weather changes. The Peruvian Guinea Pig's social and behavioural needs belong in the daily routine. The Peruvian Guinea Pig is strongly social and should normally live with compatible same-sex or appropriately desexed companions. Provide tunnels, shelters and foraging while ensuring each animal can access food and water without bullying. Handle with both the chest and hindquarters supported.
Longer coats need frequent combing and careful attention to areas that can mat or become soiled. Trim the Peruvian Guinea Pig's nails before overgrowth changes posture or movement. Preventive care for the Peruvian Guinea Pig works best when small changes are recognised early. Weigh the Peruvian Guinea Pig at least weekly because weight loss may precede obvious illness. Check the Peruvian Guinea Pig's teeth, eyes, nose, breathing, feet, coat, urine and faeces. Reduced appetite, fewer droppings or breathing difficulty requires rapid veterinary assessment.
Responsible Peruvian Guinea Pig ownership includes legal compliance and basic biosecurity. Keep only lawfully sourced Peruvian Guinea Pig animals in secure containment, never release them and check current state or territory rules before movement.
