Guinea pigs are beloved small animals worldwide, known for their gentle temperament and adorable rounded shape. With quiet vocalizations, they're easy to keep in apartments, and since they're larger and more manageable than hamsters, they're excellent companions for children. This guide covers all the essential care basics for first-time guinea pig owners.
Guinea pigs are social animals and prefer living in groups rather than alone. Housing two or more together is recommended when possible (be mindful of breeding concerns when housing males and females together).
Enclosure The minimum size should be 60 cm × 90 cm or larger. The bigger the space, the less stress your guinea pigs will experience. Since guinea pigs aren't strong jumpers, open-top enclosures with removable side panels are the most practical. Tall hamster-style cages aren't necessary.
Wooden play pens are also convenient and have the benefit of being less likely to catch guinea pig claws.
Bedding - Paper chips (most common; soft and highly absorbent) - Thick layers of hay or timothy grass (creates a natural-like environment) - Fleece liners (washable and reusable; requires washing 1–2 times per week)
Avoid metal grid floors, as they put strain on the feet.
Water Bottles Bottle-style waterers are most hygienic, as they keep water cleaner. Change the water daily.
Shelters (Hideouts) Having places to hide increases your guinea pig's sense of security. Wooden or ceramic shelters are recommended.
Hay (Timothy Grass) Hay should comprise 70–80% of a guinea pig's diet. Provide unlimited timothy hay (first cut is highest quality) by continuously refilling a hay feeder. Hay is essential for dental wear prevention and proper digestive function.
Pellets Feed guinea pig-specific pellets at about 20–30 g per day (approximately 3% of body weight). Choose pellets specifically formulated for guinea pigs with added vitamin C. Don't substitute rabbit pellets, as they contain insufficient vitamin C.
Vegetables It's important to provide vitamin C-rich vegetables daily.
Recommended vegetables: - Bell peppers (especially high in vitamin C) - Bok choy, Chinese cabbage, and broccoli - Carrots (including leaves) - Cilantro
Vegetables to avoid: - Onions, garlic, and shallots (toxic) - Potato sprouts and raw potatoes - Avocado
Guinea pigs cannot synthesize vitamin C internally and must obtain it through their diet daily (requirement: 25–50 mg/kg per day). Vitamin C deficiency causes scurvy, leading to symptoms such as bleeding gums, weight loss, and reduced mobility.
Vitamin C supplementation methods: - Daily provision of vitamin C-rich vegetables - Guinea pig-specific vitamin C supplements (tablets or powder) - Adding vitamin C to drinking water (breaks down quickly when dissolved, so daily water changes are necessary)
Ideal temperature: 18–24°C (guinea pigs dislike heat, cold, and sudden temperature fluctuations) Ideal humidity: 40–70%
Guinea pigs struggle with temperature regulation, and the risk of heatstroke rises above 28°C. Air conditioning is essential in summer. In winter, use heating devices such as pet heaters.
With proper acclimation, guinea pigs will climb onto your hands and communicate through vocalizations. "Wheeking" sounds indicate food requests, while "cooing" signals relaxation.
Start by offering food from your hand rather than forcing interaction, and gradually acclimate them. Support their belly and cup them gently in both hands to help them feel secure.
Dental Problems (Malocclusion) Occurs when teeth don't align correctly. Caused by insufficient hay or genetics. Prevent by providing hay continuously. If you notice symptoms like drooling or loss of appetite, consult a veterinarian.
Digestive Upset (GI Stasis) A serious condition where intestinal movement stops. Caused by inadequate hay, stress, or dehydration. If you notice no stomach sounds or cessation of droppings, emergency veterinary care is needed.
Scurvy (Vitamin C Deficiency) Symptoms include bleeding gums and weight loss. It's preventable with daily vitamin C supplementation.
Routine Health Checkups Annual to bi-annual veterinary checkups (at clinics experienced with exotic animals) are recommended.
With proper care, guinea pigs make wonderful family companions for 5–8 years. The basics of keeping them healthy are daily hay management, vitamin C supplementation, and maintaining a clean enclosure. We encourage you to welcome a healthy guinea pig from a breeder and enjoy the delightful experience of guinea pig ownership.
