Guinea Pig Care at a Glance

Setting Up Your Guinea Pig Cage
New Guinea Pig Owner Checklist
| Always adopt guinea pigs in pairs (same-sex or neutered pairs) | |
| Provide a cage with at least 7.5 square feet for two guinea pigs | |
| Give unlimited timothy hay for digestive and dental health | |
| Offer 1 cup of fresh vegetables per pig daily (high in vitamin C) | |
| Provide hideys — guinea pigs need covered spaces to feel safe | |
| Handle gently, support the hindquarters, and interact daily | |
| Never keep a guinea pig alone — it's illegal in some countries for good reason | |
| Do not use wire-bottom cages — they cause bumblefoot (painful foot sores) | |
| Never feed muesli mixes, seeds, or grains — they cause obesity and selective feeding | |
| Do not use exercise wheels — guinea pigs are not hamsters and can injure their spines | |
| Never house guinea pigs with rabbits — cross-species disease transmission is deadly |
Guinea pigs cannot produce their own vitamin C. Without it, they develop scurvy within 2-3 weeks — symptoms include lethargy, limping, and rough coat. Supplement daily.
Wheeking is the classic guinea pig vocalization — they learn to wheek when they hear the fridge open or rustling vegetable bags. It's their way of saying 'feed me!'
Guinea Pig Care Guide for Beginners
Guinea pigs (cavies) are among the most rewarding small pets for families and adults alike. They're social, vocal, rarely bite, and live 4–7 years — long enough to truly bond with. Unlike many small rodents, they're active during the day, making them far more interactive pets. Here's what you need to know to keep them healthy and happy.
🐷 Guinea Pig Care at a Glance
The #1 Rule: Guinea Pigs Are Social Animals
In the wild, guinea pigs live in groups. A single guinea pig is a lonely guinea pig. Most European countries have outlawed keeping guinea pigs alone. Always get at least two same-sex guinea pigs (or a neutered male/female pair). Bonded pairs are happier, healthier, and more active.
Housing and Cage Setup
Most pet store cages are too small. Guinea pigs need space to run, forage, and have separate areas for eating, sleeping, and toileting.
- Minimum size: 7.5 sq ft for 2 pigs; 10+ sq ft preferred
- Best option: C&C cage (Cubes and Coroplast) — inexpensive, customizable, and large
- Bedding: Fleece liners (washable, economical) or paper bedding like Carefresh. Never cedar or pine shavings (respiratory irritants).
- Hides: One per pig minimum; guinea pigs need places to hide and feel safe
- No wire flooring: Wire can injure feet (bumblefoot); solid floors only
Diet: The Vitamin C Problem
Guinea pigs cannot synthesize Vitamin C (like humans), so they must get it daily from food. Vitamin C deficiency causes scurvy — joint swelling, lethargy, and eventually death.
- Hay: Unlimited Timothy hay (the foundation, as with rabbits)
- Fresh vegetables: 1 cup daily per pig; focus on Vitamin C-rich foods
- Top Vitamin C sources: Bell pepper (highest), kale, parsley, broccoli, cilantro
- Pellets: ⅛–¼ cup daily of plain, Timothy-based pellets (Oxbow or KMS Hayloft recommended)
- Water: Fresh daily; bottles or heavy bowls
- Don't add Vitamin C to water: It degrades rapidly in water and loses potency within hours
What Guinea Pigs Eat (Safe vs. Unsafe)
✅ Safe Foods
- Bell peppers (all colors)
- Romaine lettuce
- Cucumber
- Cilantro, parsley, dill
- Carrot (occasional treat)
- Apple (no seeds)
- Strawberries, blueberries
❌ Never Feed
- Avocado (toxic)
- Onion, garlic (toxic)
- Chocolate
- Rhubarb (highly toxic)
- Iceberg lettuce (no nutrition)
- Dairy or meat
- Seeds, nuts, sugary treats
Grooming
- Short-haired breeds: Occasional brushing; monthly nail trims
- Long-haired breeds (Peruvian, Silkie): Daily brushing; regular trimming to prevent mats
- Baths: Every 3–6 months maximum; use small animal shampoo, dry thoroughly to prevent chilling
- Teeth: Self-maintaining through hay chewing; if you see drooling or food dropping, see a vet
Health Warning Signs
- Not eating or drinking
- Absence of droppings or dramatic change in stool
- Weight loss (weigh weekly; >50g change warrants vet visit)
- Crusty eyes or discharge from nose
- Limping or swollen joints (scurvy risk)
- Teeth chattering while handling (pain or distress)
