Guinea pigs are gentle, vocal, and full of personality—but they also require more care than many new pet parents realize. At Town N Country Veterinary Services in Hastings MN, we love helping small pet owners learn the best ways to support their guinea pig’s health, comfort, and happiness.
This guide covers the basics of guinea pig care—from housing and nutrition to wellness checks and recognizing the signs of illness in guinea pigs early.
Why Guinea Pig Care Is Different
Guinea pigs, or cavies, are prey animals. They instinctively hide signs of illness, which means health issues can develop quickly and quietly. Unlike dogs and cats, guinea pigs:
- Cannot synthesize their own vitamin C
- Need regular trimming of teeth and nails
- Require chew toys
Because of this, prevention and daily observation are key. You can read more about Guinea pig care at the Royal Society for the Prevention of Cruelty to Animals (RSPCA) website here.
How to Care for a Guinea Pig: The Basics
1. Proper Housing
- Size matters: One guinea pig needs at least 7.5 square feet of cage space; two need 10+ square feet.
- Flat flooring only: Avoid wire floors that can injure sensitive feet.
- Bedding: Use paper-based or fleece bedding. Avoid pine and cedar shavings, which release harmful aromatic oils.
- Enrichment: Include hideouts, tunnels, ramps, and chew-safe toys.
- Location: Keep the cage in a quiet, draft-free area with natural light.
2. Nutrition
- Hay: Unlimited fresh Timothy hay is the cornerstone of guinea pig nutrition—it supports digestion and grinds down teeth.
- Pellets: Choose high-quality guinea pig pellets with added vitamin C.
- Fresh veggies: Daily servings of bell pepper, romaine lettuce, cilantro, or carrot tops.
- Vitamin C: Guinea pigs must get 10–30 mg per day. Use a vet-recommended supplement or vitamin C–rich veggies.
- Water: Provide clean water in a sipper bottle or weighted bowl and change it daily.
Avoid:
- Iceberg lettuce (low in nutrients)
- Sugary fruits (limit to small occasional treats)
- Rabbit pellets (not fortified with vitamin C)

Grooming and Handling
- Nail trims: Every 4–6 weeks to prevent overgrowth and injury
- Brushing: Short-haired pigs need weekly brushing; long-haired pigs need more frequent care to prevent mats
- Bathing: Rarely needed—spot clean with a damp cloth
- Handling: Support the chest and hindquarters. Avoid sudden movements or loud noises.
Gentle, consistent handling builds trust and reduces stress during vet visits.
Guinea Pig Health Tips
- Monitor weight weekly: Sudden weight loss is often the first sign of illness.
- Check the mouth: Overgrown teeth can interfere with eating and lead to painful abscesses.
- Clean the cage regularly: Dirty bedding causes respiratory infections and skin issues.
- Watch behavior: Changes in energy, appetite, posture, or vocalizations should be taken seriously.
- Vet visits: Schedule annual wellness exams and call us right away if something seems off.

- Diarrhea or unusually soft stool
- Lumps or hair loss
