How to Take Care of a Guinea Pig

Introduction

Guinea pigs — also called cavies — are gentle, social, and vocal little animals that make wonderful pets for families and individuals alike. But they have specific needs that differ significantly from hamsters and rabbits. Here's a complete guide on how to take care of a guinea pig properly.

Guinea Pigs Are Social Animals — Get at Least Two

This is the most important thing to know before getting a guinea pig: they are highly social animals that should never be kept alone. A single guinea pig will be lonely, stressed, and prone to depression. Always keep guinea pigs in same-sex pairs or groups. Two females (sows) or two neutered males (boars) are the most common pairings.

Housing

Guinea pigs need significantly more space than most people expect. The minimum recommended size for two guinea pigs is 7.5 square feet of floor space, but bigger is always better. The 20-Panel C&C Guinea Pig Playpen (48"x24") provides excellent space and is highly customizable. For a more traditional cage, the Amazon Basics Guinea Pig Cage (47.6"x24.2") is a solid, easy-to-clean option. Hang a stainless steel hanging food bowl to keep food off the floor.

Bedding

Guinea pigs need soft, absorbent, dust-free bedding. Oxbow Pure Comfort Bedding is 99.9% dust-free and highly absorbent. Fleece liners are also popular — they're reusable, soft, and easy to clean. Avoid cedar and pine shavings.

Diet

Guinea pig diet has three essential components:

• Unlimited hay — Oxbow Orchard Grass Hay or timothy hay should be available 24/7. Hay makes up 80% of the diet.
• Fresh vegetables — 1–2 cups of fresh leafy greens daily per guinea pig. Romaine lettuce, bell pepper, cilantro, and parsley are excellent choices.
• Pellets — Wild Harvest Advanced Nutrition Guinea Pig Food or Vitakraft Menu Guinea Pig Pellets provide concentrated nutrition. Feed about ⅛ cup per guinea pig per day.

Vitamin C — Critical for Guinea Pigs

Guinea pigs cannot synthesize their own vitamin C and must get it from their diet. Vitamin C deficiency (scurvy) is a common and serious health problem. Provide vitamin C through:

• Fresh bell peppers (highest natural vitamin C content)
• Fresh leafy greens
• Oxbow Natural Science Vitamin C Supplement — a vet-recommended supplement made with timothy hay

Water

Fresh water must always be available via a no-drip water bottle or heavy ceramic bowl. Change daily.

Social Interaction and Exercise

Guinea pigs need daily floor time outside their cage — at least 1–2 hours per day. Use a portable playpen to create a safe exercise area. Guinea pigs love to explore, forage, and interact with their owners.

Grooming

Short-haired guinea pigs need weekly brushing; long-haired breeds (Peruvian, Silkie) need daily grooming. Use a soft silicone grooming brush for regular brushing. Nails need trimming every 4–6 weeks with the KALAMANDA nail clipper.

Health Basics

Guinea pigs are prone to respiratory infections, dental disease, and vitamin C deficiency. Find an exotic animal vet before you need one. Annual wellness exams are recommended.

Conclusion

Guinea pigs are rewarding pets when their social, dietary, and space needs are properly met. Always keep them in pairs, provide unlimited hay, ensure adequate vitamin C, and give them daily floor time. A well-cared-for guinea pig is a happy, vocal, and affectionate companion.
