Your guinea pig isn’t moving and you’re worried it might be hibernating. Guinea pigs don’t hibernate.
Ever. Unlike hamsters, whose metabolism slows down in winter, guinea pigs have no ability to enter hibernation.
They need a consistent temperature between 65 and 75 degrees Fahrenheit to stay healthy. Anything below 60 degrees puts them at serious risk for hypothermia.
If your piggy is still and unresponsive, it’s likely too cold or possibly sick.
Why Is My Guinea Pig Not Moving?
A still guinea pig is unusual. These are active animals, and lying on their side is a warning sign.
Normal guinea pig sleep happens standing up, usually with their eyes open. If your piggy can’t move and shows other symptoms, illness is the likely cause.
Lethargy, trouble moving, heavy breathing, panting, runny nose, weepy eyes, diarrhea, and vomiting are all signs of disease. That doesn’t necessarily mean you’re dealing with a dying guinea pig, though.
A guinea pig indoors may simply be cold or freezing. Your guinea pig’s hutch has to be in a draft-protected area, away from direct sources of heat or cold like air conditioners and heaters.
If you think your pet is too cold, try warming it up with a heating pad on a low setting, a hot water bottle placed nearby, or a towel heated in the dryer. Place extra bedding in your guinea pig’s cage for insulation.
If your pet isn’t eating or drinking, it may be sick. Take your pet to a vet immediately if your guinea pig won’t eat or drink and appears unwell.
What Temperature Is Cold for Guinea Pigs?
Freezing temperatures are genuinely dangerous for guinea pigs. Even early fall can trigger mild hypothermia in these small animals.
Guinea pigs evolved in South America. Their bodies expect warmth, not cold.
Like all animals, piggies need a comfortable environment or they can become sick. In general, guinea pigs can tolerate temperatures down to about 60 degrees Fahrenheit before they start getting cold.
If the temperature falls below that, they may become lethargic and have trouble breathing. Even then, guinea pigs won’t hibernate.
Take steps to keep your piggy warm during cold spells. Pneumonia from cold exposure is a real threat.
Simple rule: if you’re cold, your guinea pig is colder.
How Do I Know if My Guinea Pig Is Cold?
Start by checking the temperature of their environment. Below 60 degrees Fahrenheit?
Your guinea pig is probably cold.
Touch is another indicator.
When they feel cold, many guinea pigs huddle together and stay inactive. If you touch your pet and notice it has cold ears, nose, or bottom, it may need a warmer environment.
When your guinea pig is chilly, it’ll spend more time in its shelter or burrowing in hay. You’ll see it shiver and curl up to warm itself, which usually happens when the temperature falls below 60 to 65 degrees Fahrenheit.
Can Guinea Pigs Get Cold Easily?
These animals chill down fast, so monitoring them is essential. Body temperature is the most reliable check.
The normal body temperature for a guinea pig is around 101 degrees Fahrenheit. If your guinea pig’s body temperature drops below this, they may need some extra warmth.
What Is a Normal Temperature for a Guinea Pig?
A normal body temperature for a guinea pig is around 101 degrees Fahrenheit. Like humans, piggies can have different body temperatures depending on their age, health, and activity level.
If your guinea pig’s temperature falls below 99 degrees or rises above 103 degrees, bring them to the veterinarian as soon as possible. Guinea pigs can’t preserve heat well during cold weather.
Guinea pigs are prey animals, which means they’re naturally scared of things that could hurt them. This can make taking their temperature difficult.
You can try using an electronic ear thermometer or a digital infrared thermometer. If your guinea pig won’t cooperate, you can use an external rectal thermometer instead.
Just be sure to clean it well before and after use.
A healthy guinea pig’s ideal temperature usually falls between 99 and 103 degrees Fahrenheit.
Can Guinea Pigs Die from Hypothermia?
Absolutely. Guinea pigs can die from hypothermia.
In temperatures below 50 degrees Fahrenheit, guinea pigs are at serious risk for this condition, which can be deadly.
Hypothermia occurs when these small animals lose body heat faster than they can produce it. Even then, guinea pigs don’t hibernate.
Instead, they show signs like quick and shallow breathing, and their hair may stand on end as the body tries to conserve heat.
If your home is too cold, place your pet’s cage in a warm spot near a heat source, or provide extra bedding. You can use shredded paper, wood shavings, and fleece as the top layer.
Make sure your pet’s cage has a heated pad or proper insulation. If your guinea pigs appear to be shivering or have difficulty breathing, take them to the vet immediately.
When you’re away from home, you can use a space heater, heating pads, and snuggle pads to keep the air temperature warm. Keep the heater away from your guinea pig’s cage and monitor it constantly to prevent overheating.
Never leave your guinea pig in a car on a cold day. The temperature inside a car can quickly drop to dangerous levels.
Don’t forget about summer care either. Change the water in their bottle regularly, provide fresh food and shade, especially if they’re kept outside in a hutch.
Guinea pigs shouldn’t live outside, and they definitely shouldn’t spend time outdoors during cold seasons.
Keep up with regular grooming too. Long hair can become matted and full of dirt in the summer heat.
A good brush makes a big difference in coat health.
How To Help a Guinea Pig Warm Up
A guinea pig’s body temperature is important for their overall health. When they get too cold, they can’t move around or digest food properly.
If your pets seem too cold, take action right away.
Here are a few ways to help your pets stay warm:
- Put them in a room that isn’t too cold
- Give them a warm place to hide
- Make sure their cage has plenty of bedding
- Put a hot water bottle in their cage
- Give them fresh food and lukewarm water
A guinea pig’s home has to be in a warm place with enough space to feel comfortable. Guinea pigs love to roam around at all times.
To keep your guinea pig warm, you can use heating pads placed under the bedding or a ceramic heat emitter. Make sure they also have plenty of bedding and a snuggle pad.
Change the bedding frequently, as wet bedding does more harm than good and can cause many health issues. You can also place a hot water bottle near their bedding for extra warmth.
If you’re going to be away, make sure to leave your guinea pig in a warm environment with plenty of food and water.
What Temperature Is Warm for Guinea Pigs?
Guinea pigs enjoy spending time in the sun, but they need protection from the heat. Their body temperature can get too high if exposed to excessive warmth, causing serious health problems and even death.
Native to South America, guinea pigs find an ideal temperature range between 65 and 80 degrees Fahrenheit. If temperatures exceed 85 degrees, take steps to cool your guinea pig down by moving it to a cooler area or giving it cold water.
Humidity affects a guinea pig’s body temperature too. When the humidity is high, the temperature feels hotter.
So if it’s hot and humid, keep your guinea pigs in a cooler area.
Here are ways to cool down an overheated guinea pig:
- Move the guinea pig to a cooler area
- Give the guinea pig cold water to drink
- Fan the guinea pig
- Put ice packs underneath its fur
- Apply aloe vera or another cooling ointment to its skin
Direct sunlight can cause a guinea pig to overheat quickly, so provide plenty of shade for your guinea pig to relax in.
Can Guinea Pigs Live Outside?
Nope. Guinea pigs shouldn’t live outside regardless of the time of year.
The cold can be dangerous and lead to health problems like pneumonia.
In winter, it’s important to provide your guinea pig with a warm place to stay. While hamsters hibernate throughout the winter, guinea pigs and chinchillas don’t.
Keeping them at temperatures below 60 degrees Fahrenheit isn’t safe.
Is It OK to Keep Guinea Pigs Outside?
Whether you can keep your guinea pigs outside for short periods depends on many factors. Guinea pigs can’t handle drastic temperature changes and can only tolerate temperatures between 60 and 80 degrees Fahrenheit.
If you live somewhere where the temperature regularly falls below 50 or rises above 80, it might not be safe to keep your piggy outside. If there are lots of predators in your area like coyotes or raccoons, that’s another reason to keep them indoors.
It’s up to you, but do your research and consider all the potential risks.
What Temperature Can Guinea Pigs Stay Outside?
Guinea pigs can stay outside if the temperature is above 60 degrees Fahrenheit. If it’s below that, they should be brought inside.
They also need access to water and food, and they should be in a shaded area. Bringing them in at night is important to keep them safe from predators.
Can Guinea Pigs Be Outside in Winter?
Guinea pigs can be outside briefly in winter as long as they have a warm place to go if they get too cold. Of course, it can’t be too cold outside.
Guinea pigs can’t tolerate temperatures below 60 degrees Fahrenheit. If it’s colder than that, make sure your piggies are inside and warm.
Give them plenty of food and water, and check on them often.
Guinea pigs shouldn’t run loose outdoors. They aren’t built to deal with the cold, and staying outside in the snow can make them severely ill.
Final Thoughts
Guinea pigs don’t hibernate, period. If your piggy is still and unresponsive, it’s either too cold or possibly sick, and both situations need immediate attention.
Keep their environment between 65 and 75 degrees Fahrenheit year round. Invest in proper bedding, avoid drafts, and never leave them in unheated spaces during winter.
Check on your guinea pigs regularly, especially during temperature changes. A little prevention goes a long way in keeping your guinea pigs safe and healthy.
Frequently Asked Questions
Guinea pigs may become less active in cold temperatures, but they don't truly slow their metabolism like hibernating animals. They're simply uncomfortable and conserving energy. If your piggy seems sluggish in winter, check that their environment stays between 65 and 75 degrees Fahrenheit.
Guinea pigs can freeze to death if exposed to temperatures below 50 degrees Fahrenheit for too long. Their small bodies lose heat rapidly and can't generate enough warmth. Hypothermia sets in quickly, so always keep their living area well above that dangerous threshold.
Heat lamps aren't recommended because guinea pigs can overheat quickly and suffer burns. A safer option is a low-setting heating pad placed under part of the cage bedding. This lets your piggy move toward or away from warmth as needed without overheating risk.
Signs include shivering, cold ears and feet, shallow breathing, lethargy, and unresponsiveness. Your guinea pig's fur may stand on end as its body tries conserving warmth. If you notice these symptoms, warm your piggy gradually with blankets or a heating pad and contact your vet.
