Guinea Pigs keeping warm

Do you wonder how to keep guinea pigs warm in winter? Or just warm in general?

Whether you keep them indoors or outdoors, its very important that you keep your guinea pigs warm.

But how exactly do you do that?

The aim of this article is to give you some tips and ideas on how to keep your guinea pigs warm.

When I first got Guinea Pigs, I was so stressed about getting the temperature just right for them. Even though they are susceptible to cold, you don’t need to worry about it until the temperature is below 16°C(60°F).

If it does get below this then you might want to make a couple of changes to keep them warm.

Depending on where you are, you might need to learn how to keep guinea pigs warm in the winter months more.

Since it can get very cold during these winter months it’s really important. We don’t want them to be getting hypothermia.

Before we look into how to keep guinea pigs warm. It’s important to first understand what temperature they should be.

How Warm Do Guinea Pigs Need To Be?

Its very important to try and keep your guinea pig between 16°C(60°F) and 24°C( 75°F ). If they’re indoors then this is usually much easier to do.

You may want to look at ways of keeping them within this temperature, if you keep them outside and have cold winters.

NOTE: Although just because they are kept inside, you should still keep an eye on their temperature. It’s very easy for them to get too hot and therefore risk overheating.

The risk of them getting a disease or even dying from the cold is high if their temperature gets below 16°C(60°F).

Should you move your guinea pigs indoors for winter?

Holding a Cold Guinea Pig

If you usually have your guinea pig outside, you might be wondering if its worth moving them indoors.

Yes if possible, it would make it easier to keep guinea pigs warm if you brought them inside.

Unless you take a lot of steps to keep them warm, they can get very cold in the winter and even at night when the temperature drops.

Just bear in mind that unless you can move your outside cage inside, you may need to get another cage.

If there is no way you can bring them in, its no big deal. There are ways to keep your guinea pig warm outside.

Ways To Keep Your Guinea Pig Warm Outside

Knowing how to keep guinea pigs warm in winter is very important if you keep them outside. Although it’s not just important to keep them warm at winter….

In autumn it can also get very cold in the evenings and at night.

Luckily, there are a few things that you can do to keep them nice and cosy in their outside hutch. Which means your guinea pig can enjoy living outside all year round.

1. Have more Guinea Pigs

You should never just have one guinea pig as they are very social-able. They need to be around other guinea pigs to be happy and content.

If you do have the space, it would be worth getting a few more guinea pigs. You see when they start to get cold, they cuddle up together.

Not only does this look cute but it allows them to use one another as a heat source, warming each other up.

2. Insulate Their Hutch

One option would be to insulate their hutch. This would make it harder for the cold to get inside.

It’s not an easy job or one that could be done in a day but it can help them stay warmer at night and during winter.

You can insulate your guinea pigs hutch at a very low cost. Just use an old blanket or something similar and place it over the hutches roof and the external walls.

NOTE: Make sure that the hutch still has decent ventilation.

3. Lift the hutch off the ground

To also help keep them warm at night, you can lift the guinea pigs hutch off the ground slightly.

If they’re only an inch or two from the floor, this stops the damp rising up into the hutch.

This will also help your hutch last longer, since the moisture wont rot the wood.

4. Keep the hutch dry

In the cold its important to keep the hutch dry. This will stop the damp from making your guinea pigs cold and could even cause them to get sick.

You can keep the hutch dry by lining the bottom of the cage with newspaper. That way any water that gets in the hutch will get soaked up by the paper and not make their home wet.

To also keep it dry you want to change soiled bedding and any areas that might get wet. I.E near bowls and bottles.

5. Use heating pads

Now when I mention heating pads, I don’t mean those pads that you need to plugin or microwave. These are self-heating pads that warm up when your guinea pig is laying on it.

This will help keep them warm but prevent them from burning themselves.

NOTE – You should always make sure there is an area in the hutch that is not covered by the heat pad. This allows your guinea pig to get away from the heat if they’re getting too hot.

6. Keep the food and water topped up

To help keep guinea pigs warm, keep an eye on their food and water. You want to make sure there is always plenty of food and drink.

This is because they tend to burn more calories to help them keep warm.

7. Provide your guinea pigs with space to run

Have you ever been cold and gone for a run and felt hot? Exercise is a great way of getting warm when out side. This is because exercising helps to increase blood flow around the body which helps to keep you warm.

The same thing happens to guinea pigs, so you may see them running around when cold. You therefore need to make sure they have plenty of space to run around and exercise.

8. Move the hutch

Finally as well as moving the hutch off the ground or indoors. You want to try and move it into a garage or shed. If you cannot do this due to the size, try and move it away from weather conditions.

If it’s raining, you don’t want the rain to get into the door. The same is said if it’s really windy, try and keep the wind out of the hutch.

5 Ways To Keep Guinea Pigs Warm Indoors

Eating Guinea Pig

What if you keep your guinea pigs indoors, you still need to make sure they are warm enough. This is important at night when the temperature drops and we might not realise since we’re covered in a warm duvet.

1. Position the cage in the right place

Just like outside, you need to think about the location of their cage. You want to keep the temperature as consistent as possible, as fluctuations could cause your guinea pig to get sick.

Don’t put the cage near windows that are open or opened often. You might also not want to put it near locations that can get drafts.

NOTE: Don’t put the cage near radiators as this could cause your guinea pigs to get too warm.

2. Add some heating areas

Even indoors you might want to consider using a self heating pad. This will help them get that little extra warmer, just make sure they have an area that doesn’t have the pad so they can get cool if they need to.

You could use a heater but I personally wouldn’t recommend it, as it makes it harder for them to find a cool area.

3. Insulate the cage with layers

If you only need to increase their temperature a little bit, adding some insulation is the best way.

Just adding a layer of blankets or even shredded paper on the bottom will help give that little extra heat. Helping your guinea pig to feel nice and cosy.

4. Create snuggles areas inside the cage

It’s possible that your guinea pigs can actually keep themselves warm enough, if you give them areas to do it.

Guinea Pigs love to cosy up to each other and cuddle, as this helps them to keep each other warm.

To help encourage this get some nesting boxes or boxed areas and fill them with hay. They will then huddle inside of these to cosy up and keep warm.

5. Ensure your guinea pigs have plenty of food and water

I mentioned above when outside to keep the food and water topped up, the same should be done inside as well. Remember Guinea Pigs are awake for 20 hours a day, so they burn a lot of calories. Even more so when trying to keep warm.

So keeping these full will help give them the calories they need.

Don’t forget to give them plenty of hay, pellets and even fruit and vegetables to help give them additional nutrients. This is going to improve their immune system, which can help prevent them from getting sick if cold.
