Guinea Pig Care Guide: A Complete Guide for Macau Owners
Guinea pigs are gentle, social pets popular in Macau. Learn about their housing, diet, health needs, and why they make excellent family pets.
Guinea pigs (cavies) are gentle, social rodents that make excellent pets — especially for families with children. They rarely bite, are easy to handle, and communicate with a delightful range of sounds (wheeks, purrs, and chirps). Guinea pigs live 5-8 years with proper care, making them a longer commitment than hamsters. They are social animals that thrive with companionship and need a spacious habitat.
Key Points
- Guinea pigs need unlimited timothy hay as the foundation of their diet
- They cannot synthesize Vitamin C — daily supplementation is essential (like humans!)
- Guinea pigs are social animals — keep them in pairs or small groups
- They need spacious housing with at least 7.5 square feet for a pair
- Guinea pigs are sensitive to heat — keep them in air-conditioned spaces in Macau's summers
- Regular nail trims and occasional baths are part of their care routine
Diet and Nutrition
The foundation: unlimited timothy hay (80% of diet) — essential for dental health and digestion. Pellets: high-quality guinea pig pellets with added Vitamin C (1/8 cup daily per pig). Vegetables: bell peppers (excellent Vitamin C source), romaine lettuce, cilantro, carrots, cucumber — daily. Fruits: small amounts of apple, strawberry, blueberry as treats. NEVER feed: iceberg lettuce (low nutrition, diarrhea), potatoes, onions, chocolate, dairy.
Vitamin C Requirement
Guinea pigs, like humans, cannot produce their own Vitamin C. Deficiency causes scurvy — swollen joints, bleeding gums, lethargy, and potentially death. Provide Vitamin C through: bell peppers (red bell pepper has the highest Vitamin C), guinea pig pellets fortified with Vitamin C, or Vitamin C drops in water (replace water daily — Vitamin C degrades quickly). Daily requirement: 10-30mg per kg body weight.
Housing
Guinea pigs need spacious cages — minimum 7.5 square feet for a pair (C&C cages or large indoor enclosures). Line with paper-based bedding or fleece liners (never cedar or pine shavings — toxic to guinea pigs). Provide hideouts (igloos, tunnels) for security. Include a water bottle and hay rack. Place in a quiet room away from predators (cats, dogs) and direct sunlight. Temperature: 18-24°C — guinea pigs are heat-sensitive.
Common Health Issues
Dental problems: overgrown teeth from insufficient hay — provide unlimited timothy hay. Respiratory infections: sneezing, nasal discharge — caused by drafts or dirty bedding. Scurvy: Vitamin C deficiency — swollen joints, lethargy. Bumblefoot: sores on feet from wire-bottom cages or hard surfaces. Mites/lice: scratching, hair loss. Guinea pigs hide illness well — any change in eating, behavior, or droppings warrants a vet visit.
When to See a Vet Immediately
- Your guinea pig has stopped eating or producing droppings for more than 12 hours
- Your guinea pig has difficulty breathing, sneezing, or nasal discharge
- Your guinea pig has swollen joints or difficulty walking (possible scurvy)
- Your guinea pig has overgrown teeth or drools excessively
- Your guinea pig is scratching excessively or has hair loss
- Your guinea pig has diarrhea or soft stools that persist for more than a day
