What Temperature Is Too Cold For Guinea Pigs?

Cavies love the temperature between 18 and 23 degrees, and too high or too low of that range can be very cold or very hot for them.

Are you curious about what temperature is out for them? (please read here what is the coldest temperature a Guinea pig can live in)

Well, if it drops to 15 degrees, that is the time that your beloved pet will get the chills.

You need to know this information because when a guinea pig gets cold, its body’s blood flow reduces.

Due to that, the skin tends to diminish in conserving heat, which will make your cavy all chilled out.

On the other hand, guinea pigs cannot sweat since they lack sweat glands.

As a pet owner, you must better understand these tiny details if you want to make your pet feel comfortable every time.


Steps To Keep A Guinea Pig Warm Inside The House

It is known that guinea pigs are inevitably susceptible to hot and cold temperatures.

So during the cold days, you have to expect that your pet will be very cold, and it is time for you to make a move!

I am a cavy owner, and I have an adorable guinea pig named Ginger. I have been with him for about nine months now, and I surely know that he hates the winter season.

The following are the steps I did to help him ease the chilly situation, and it was very beneficial for him:


Step #1. Bring your pet inside

The best thing that you can do on cold weather days is to bring your pet inside the house.

Since guinea pigs can get hypothermia, do not let them out in temperatures you think they can’t tolerate.

If you cannot put your pet indoors, you might as well take much effort to keep it warm even outside. (please read here how to make a Guinea pig cage out of a bookshelf)


Step #2. Insulate

Block any spaces that can let the chilly breeze in.

Since I live in an old house, the drafts are sure to make some of the rooms cold enough to make me shiver. I used towels to block it.

I make sure that Ginger is fine and warm in her hutch.


Step #3. Make sure your pet is away from openings

Place your cavy away from windows and doors, and the best position would be the center of the house. Why?

Because exterior doors and windows will be much colder and being at the central part of the house would decrease the cold’s chances of giving your pet discomfort.


Step #4. Put additional towels and blankets

These things can help trap heat inside the cage. Your cavy will surely snug into these and will make itself comfortable.


Step #5. Use hay or shredded papers

It would be great if you add hay and shredded papers as its bedding.

The grass is an excellent choice that you can have because it reacts well with moisture and traps heat effectively.

Please do not use any beddings that contain chemicals because guinea pigs tend to eat its bedding (all the time).


Step #6. Put a box or hutch

You can have the option of putting a box or hutch in the cage of your beloved pet (like I did) so that it can curl itself inside.

Or maybe, try to have a warm sleep mat pad for guinea pigs.


Step #7. Place a heating pad

Another thing that you can add is a heating pad and you must put the pad in the microwave to heat it up.

Place it beside your pet and it will give at least 8 hours of adequate heat to your guinea pig.

Anyway, there are also electric heating pads for guinea pigs; they’re even more convenient to use (I mean, in your part).

If you are wondering where to buy them, these heating pads are widely available in pet stores and even online.


Steps To Make A Guinea Pig Warm Outside

Like I have said a while, if there is a situation going on and you cannot let your guinea pig inside the house, here are the steps to give it heat:


Step #1. Get your pet a hutch

Since the wind will be too cold for your pet, you must have an excellent and well-insulated hutch for it.

Though it comes with quite an amount, you can consider it as a wise investment for more winter seasons to come.


Step #2. Move the cage

Here’s the next thing you should do:

Move the cage into your garage or even on a shade to avoid the danger of too much snow or rain.

If you do not have either of these, try to put the cage in a shaded place outside of your house.

This action should be better than your pet having no shade at all against the rain and snow.


Step #3. Insulate

Insulation is one of the essential things you must consider because it will determine your pet’s comfortability.

For the worst case, not having enough insulation will cause your cavy to fall sick and might be seen cold and dead the next day (and it is something you surely do not want to happen!).


Step #4. Elevate the hutch

If you have a good quality of hutch, you might as well place it in a more elevated manner because that action can trap more heat.

Moreover, the dampness won’t have any chance of dominating your pet’s cage.

You need to understand that cold can creep into the ground and decrease the heat, so it is much better to elevate the hutch.


Step #5. Put beddings

Lastly, two-three-inch bedding made of fresh hay and other viable beddings can make your pet happy even on winter days. (please read here how to make Guinea pig happy)

With the nice bedding, body heat will be trapped effectively, and the coldness won’t be a big problem anymore.

All you have to do is follow these steps correctly so that you’ll know better how to keep guinea pigs warm.


Signs That A Guinea Pig Is Cold

Thankfully, the signs which you can tell that your cavy is having chills are very straightforward.

As a pet owner, whether your guinea pig is indoors or outdoors, you have to be keen and observe well for the possible signs that your pet is cold.

Here are the following signs that you must be aware of:


#1. Shivering

It would be a super obvious sign that your cavy is feeling cold when you see your pet shivering.

Like us humans, these tailless rodents can also react to cold quickly and will shake and tremble due to the chilly breeze.


#2. Curling up

If you see that your cavy is huddling, that is another obvious sign that it is cold.

Imagine us all curled up in our blankets during a snowstorm, and that is exactly what your beloved pet is feeling.

It would help if you immediately found something that will make it all warmed up, like blankets or heating pads.


#3. Cold ears

Once you are unsure if your guinea pig needs warmth or not, feel your cavy’s ears. (please read here how to clean Guinea pig Ear)

Though this method has not been scientifically proven, this method should do the trick.

I am sure that you are familiar with the temperature of its ear during regular days, so when you think it is a bit cold, your beloved pet is probably having discomfort due to the coldness of the weather.



In conclusion, it is better to keep your guinea pigs inside during winter because it will be much warmer inside.

However, if you cannot do anything to place it in your house, try to do your best to warm your cavy even outside the home.

Be mindful that the cold will indeed cause danger and harm to your pet that will even become fatal.

As a pet owner, you also have to be vigilant about the signs of your pet being cold so that you can immediately take action about it.
