Temperament & Appearance

Peruvian guinea pigs are inquisitive, alert, and surprisingly brave compared to other breeds. Their bodies grow to 7‑10 inches, and their coats—especially the “mane” that starts along the back—require regular maintenance.

These gentle, intelligent pets are playful and thrive on interaction, making them delightful companions for the right owner.

Grooming

Daily brushing is essential to prevent matting and the severe condition known as flystrike. Brush each day and perform a quick check and cleaning (wash the lower half only) once or twice daily. Keep the cage clean daily as well.

Lifespan

While most guinea pigs live 5‑8 years, Peruvian guinea pigs can reach an impressive 12‑14 years with proper care.

Cage Requirements

Space matters: a single guinea pig needs at least 7.5 sq ft; for two or more, aim for 10 sq ft or more. Choose a cage with tightly spaced, chew‑proof bars—metal is ideal, but high‑quality plastic works too. Place the cage in a quiet, safe area away from children, other pets, and television screens.

We recommend the Prevue Indoor Guinea Pig Cage, favored by breeders and societies worldwide for its size and durability.

Bedding

Straw is unsuitable for Peruvian guinea pigs because it can become tangled in their long hair. Opt for pet store‑sourced aspen wood shavings or paper‑based bedding. For more options, see our article on alternative bedding choices here.

Food & Water

Nutrition is critical. Guinea pigs cannot synthesize vitamin C, so a diet rich in fresh produce and fortified pellets is mandatory to prevent scurvy.

Vitamin C

Provide daily fresh fruit or vegetables high in vitamin C, and supplement with Small Pets fortified Pellets on Amazon ↗️. Vitamin C treats are also available as a supplement.

Timothy Hay

Unlimited access to fresh Timothy hay keeps teeth in check and offers essential fiber. This low‑sugar, high‑fiber option aligns with a guinea pig’s natural diet.

Pellets

Supplement with nutritionally balanced pellets that contain protein, fiber, and vitamin C.

Fruits, Veggies & Greens

Daily fresh produce enriches the diet with antioxidants and vitamins. Choose safe options and limit portions to avoid digestive upset.

• Fruits: Raspberries (1‑2 per week), strawberries (up to ⅓ per week), oranges (1‑2 slices 2‑3 times a week), apples (½ cup 1‑3 times a week), blueberries, blackberries, peaches, etc.
• Veggies: Red/green bell peppers, cucumber, broccoli (small portions), carrots, cauliflower leaves—always check for safety.
• Greens: Romaine lettuce, red & green leaf lettuce, dandelion greens, carrot tops, cabbage—always verify compatibility.

Sociability

Guinea pigs are herd animals and thrive in groups of the same gender. Peruvian guinea pigs are particularly sociable with humans and enjoy petting and hand‑feeding.

Exercise

Provide safe, guinea pig‑proof play areas outside the cage to allow stretching and exploration. Consider low ramps to prevent falls and keep the environment secure from cords, toxic plants, and predators.

Final Thoughts

With proper grooming, nutrition, housing, and affection, Peruvian guinea pigs can become long‑lived, healthy, and loving pets. The basics—diet, daily care, and social interaction—are the foundation of a thriving companion.
