Complete Guide to Guinea Pig Care and Health
Learn comprehensive care for happy, healthy guinea pigs — housing, temperature, social requirements, nutrition with vitamin C supplementation, handling tips, and common health concerns.
Guinea pigs require spacious living that allows them to move freely. A minimum cage size of 7.5 square feet (700 square centimeters) is recommended for single animals, but pairs need at least 10-12 square feet (900-1100 square cm) with hiding places and visual barriers to reduce stress. Avoid wire mesh flooring as it can cause foot injuries; opt for solid bottom enclosures like wood or plastic.
Temperature control is crucial. Maintain a temperature range of 65°F to 75°F (18°C to 24°C), with the cooler end of this spectrum preferred. Humidity should be kept between 50-60%. Avoid placing cages near windows that receive direct sunlight, which can cause overheating and UV damage.
Guinea pigs are herbivores requiring a diet rich in fiber. Feed them high-quality guinea pig pellets specifically formulated with vitamin C (which they cannot produce naturally) as the main staple — about 1/4 to 1/2 cup per pound of body weight daily, divided into 2-3 meals. Supplement with fresh veggies like leafy greens, carrots, and cucumbers in moderation (no more than 10% of their diet), avoiding high-starch foods that can lead to obesity.
Fresh water must always be available, changed daily. Provide hiding places, toys, and chew materials like untreated wood blocks or hay to keep them mentally stimulated and prevent boredom-induced chewing behaviors.
Guinea pigs are social animals that thrive in pairs. Keep two guinea pigs together from an early age if possible, as introducing adults can lead to aggression issues. Always supervise interactions closely, especially during feeding times when competition may arise.
Handling requires gentle care. Support their body and lift them carefully, avoiding sudden movements or picking them up by the ears/legs. Start with short sessions (5-10 minutes) and gradually increase time as they become more comfortable with your touch. Regular interaction helps guinea pigs become tame and reduces stress.
Common health issues include respiratory infections from poor ventilation, vitamin C deficiency leading to scurvy symptoms like swollen joints, skin problems from inadequate humidity, and dental issues requiring professional veterinary care. Monitor their stool quality — soft pellets can indicate digestive problems — and seek immediate veterinary attention for any signs of illness or distress.
