Many pet owners wonder: “Do guinea pigs hibernate?” The answer is no, guinea pigs do not hibernate. Unlike some small animals such as hamsters or hedgehogs, guinea pigs stay active all year round. If your guinea pig becomes inactive or cold, it’s usually a sign of temperature stress or illness, not hibernation.
Understanding Guinea Pig Behavior in Cold Weather
Guinea pigs are originally from the Andes Mountains in South America, where the weather is cool but not freezing. Over time, they’ve adapted to mild climates — which means they don’t tolerate extreme temperatures well.
When the temperature drops below 60°F (15°C), guinea pigs can become sluggish and less active. If it goes below 50°F (10°C), they risk hypothermia. So, if your guinea pig seems to be “hibernating,” it might actually be too cold.
Ideal Temperature for Guinea Pigs
The best temperature for guinea pigs is between 65°F and 75°F (18°C–24°C). This range keeps them comfortable and healthy. Always make sure their cage is in a warm, draft-free area during winter. Avoid keeping them in garages, balconies, or outdoor cages when it’s cold.
Signs Your Guinea Pig Is Too Cold
If your guinea pig appears still, cold to the touch, or breathing slowly, it’s not hibernation — it’s hypothermia. Common symptoms include:
- Shivering or trembling
- Weak movement
- Lack of appetite
- Cold ears or feet
If you notice these signs, move your guinea pig to a warm indoor area immediately and wrap it in a soft towel. You can use a heating pad (on low) under half the cage so your pet can choose a comfortable spot.
Do Guinea Pigs Like Warm Weather?
While guinea pigs dislike the cold, too much heat is also dangerous. They can suffer from heatstroke if the temperature rises above 85°F (29°C). Always keep them in a cool, shaded area during summer and ensure they have fresh water at all times.
How to Keep Guinea Pigs Comfortable Year-Round
To prevent cold-related problems:
- Keep their cage indoors during winter.
- Use extra bedding like hay or fleece liners.
- Avoid placing the cage near windows, air conditioners, or heaters.
- Provide fresh vegetables like cucumbers, lettuce, and bell peppers for hydration.
When to Call a Vet
If your guinea pig suddenly stops moving, eating, or making noises, it’s time to see a veterinarian. These signs may indicate illness or hypothermia, not hibernation. Quick treatment can save their life.
Conclusion
So, do guinea pigs hibernate? No, they don’t. Guinea pigs are active all year long, even during winter. If they seem less active in cold weather, it’s likely because they’re too cold — not hibernating. Always maintain a safe, comfortable temperature, provide proper nutrition, and keep an eye on any changes in their behavior.
With the right care, your guinea pig will stay healthy, active, and happy all year round.
