What is the Best Bedding for Guinea Pigs?

It's important to use good quality bedding for your guinea pig’s hutch or cage so they are comfortable and to prevent illness or injury. Your pets need to be warm enough and the bedding should be soft to protect their delicate feet. Guinea pigs, unlike some other small pets, should never be placed in cages or hutches that have a wire bottom. It should always be covered with a flat smooth surface on which the bedding can be laid.

There are several types of bedding to choose from so we take you through the different ones and explain which are best.

Best bedding for outdoor hutches

As well as making sure the bedding you buy is comfortable for your guinea pigs, two important points to consider when determining the type of bedding you are going to put in an outdoor hutch are:

  • ensuring your guinea pigs are warm enough 
  • making sure the hutch is always as hygienic and clean as possible


Guinea pigs like the same temperatures as we humans so always put yourself in their position. If you would find it too cold/hot then they will too and this can be extremely dangerous for them. It’s important they have the right bedding to keep them warm.


An outdoor hutch that is not kept clean will attract flies and this can be fatal. It’s important to choose bedding that is absorbent and easy to clean out and to replace the bedding on a regular basis.

Hutch bedding and how to arrange it

A hutch should have 2 sections - a dark protected sleeping area and a larger area fronted with wire mesh. It’s a good idea to cover the bottom of the hutch in both sections with a thick layer of  wood-based or paper based bedding such as Fitch, Megazorb or kiln dried wood shavings. This will absorb urine and help keep it fresh. 

In the sleeping area, add plenty of hay to help keep your small pets warm in the cooler weather. It’s also advisable to add a pigloo or a large and thick snugglesack they can snuggle right into to keep warm. A pigloo can be stuffed with hay and this will give added warmth in the hutch. 

Adding a layer or so of newspaper to the bottom of the hutch before adding the bedding makes the job of cleaning out a lot easier as you can simply roll it all up and remove from the housing.

Bear in mind that a snugglesack will need regular washing - probably every 3-4 days so it’s advisable to buy at least 2 of these. 

Best bedding for indoor cages (incuding C&C cages)

Probably the most important things to think about when choosing bedding for an indoor cage are:

  • To make sure it doesn’t smell offensive and keeps the cage smelling fresh
  • To choose one that it doesn’t make a mess of the space around where the cage is kept
  • Is easy to clean and dispose of

Choosing a bedding that is absorbent and won't make your home smell weird

When you're looking for bedding for an indoor cage, it's essential to find one that is both absorbent and that doesn't have a smell you don't like. Some bedding has a particular smell to it which some people will like and others won’t. This is down to personal taste so it may be that you need to try out different types of bedding before you settle on one you like. Fleece bedding is probably the only option that has absolutely no smell at all. 

Guinea pigs are not really smelly animals when they and their cage are cleaned regularly. A dirty cage (however absorbent the bedding is) will begin to have a nasty ammonia type of smell from the urine and is extremely unhealthy for your small pets.

Choosing bedding that doesn’t make a mess of your space

If you are house proud, it will be important that the bedding doesn't drop out of the cage and on to your carpet or flooring. Of course, it is quite easy to vacuum but frustrating when you have just cleaned the floor if bits of shavings etc find there way back there straight afterwards!

The cages we recommend have solid sides part way up the cage but you will still find the odd bit escaping every now and again. The only bedding that you can be sure won’t do this is fleece liners.

Ease of cleaning and disposal

You can either use disposable or washable bedding for an indoor cage.  If you are using wood or paper-based bedding, adding a layer of newspaper beforehand will make it easier to clean as you can simply roll it up and either put it on your compost heap or put in a black sack. Otherwise, you can easily use a dustpan and brush to sweep it out.

Fleece liners are very easy to remove from the cage but it does need to be shaken (so no large bits of hay etc end up in the washing machine) washed and dried so you must have at least 2 sets of bedding if using this option.

Bedding options and recommendations


Lots of hay is essential for the sleeping quarters of an outdoor hutch, providing warmth and insulation. 

Pillow Wad Hay - Hay for Guinea Pig Bedding and Feeding

It is vital you buy the right type of hay. Some feeding hay can be quite rough so you need to look for a good soft hay which is comfortable for bedding. 

The other thing you must look for is a hay that is dust-extracted.  Dust is extremely bad for guinea pigs as they are very prone to respiratory infections which are incredibly dangerous for them. It’s not always easy to find a brand that is perfect as the quality can vary each time you buy it depending on time of year etc. Also, you may find when you get to the bottom of the bag, it is quite dusty. If this is the case, you should discard the dusty hay and start a fresh pack.

The one we’ve found to be the best is Pillow Wad hay. Even the quality of this can be variable but generally it’s pretty good and quite soft. You can buy it in large packs which is the best way to purchase as it will need to be changed on a regular basis and buying larger quantities generally works out more cost effective.

Bear in mind that you don’t necessarily need hay as bedding for an indoor cage but you must have feeding hay.

Wood-based bedding

There are several different types of wood-based bedding that is suitable for both indoor and outdoor guinea pigs. 

Kiln-dried wood shavings

It is important not to just buy any old wood shavings. Most wood shavings are pine and this type of wood contains aromatic oils (or aromatic hydrocarbons also known as phenols). These oils can cause respiratory problems in guinea pigs.

However, kiln-drying removes most of these oils and many experienced guinea pig owners report no problems with the use of kiln-dried wood shavings.

Therefore, if you want to use wood shavings, make sure it says on the packet they are “kiln-dried” before you purchase. It is worth noting that cedar shavings are NOT suitable at all due to the excessive amounts of these oils contained in the wood. The wood shavings we recommend are Pillow Wad Kiln Dried Wood Shavings

Wood pulp bedding

An alternative to wood shavings are products made from wood pulp and these claim to be more absorbent than shavings. 

The most popular wood pulp beddings are Megazorb and Carefresh. Both of these are dust-extracted and absorbent and are a good option for outdoor or indoor guinea pigs. 

Megazorb, made from virgin wood pulp, claims to be 4 times more absorbent than wood shavings and is biodegradable and its drying process kills mould or spores.

Carefresh Natural claims to last twice as long as traditional bedding and is also heat-treated to remove bacteria, mould and fungus. 

Paper-based bedding

Paper-based bedding is a soft disposable bedding and is a good choice for both outdoor hutches and indoor cages. The most popular paper bedding products are Fitch and Kaytee.

Fitch, a recycled product, is a highly absorbent and soft bedding, made from a high grade food paper which is shredded into pieces that measure about 15mm-20mm. 

Kaytee Natural is another highly absorbent paper-based option which absorbs 6 times its weight in liquid and is twice as absorbent as wood shavings. This ultra-soft bedding is made from paper trimmings from the health, hygiene and food industries that are too small to be used in other products.

Cage fleece liners

Fleece Liners are an excellent choice for indoor guinea pigs but quite different to other types of bedding. There are many good reasons why you may want to use fleece liners:

Firstly, you will have no dust at all with a fleece liner. This is great news as guinea pigs are very susceptible to respiratory problems. Using fleeces in your guinea pig’s cage can reduce the likelihood of them getting these nasty and often deadly infections.

If you want your guinea pig’s cage to look beautiful, a fleece is the perfect base. They come in many different colours and with various patterns including wacky, fun and cute. They are also made to fit the cages we recommend and can also be custom made at a very reasonable price.

Fleece liners mean you don’t need to be throwing away bedding which is more environmentally friendly. Of course, this needs to be balanced with the fact they will need washing but it seems a greener option than disposable bedding. 

Fleece liners vary in thickness depending on who you buy them from. You will want them to be as absorbent as possible so your cage smells fresh and your guinea pigs are kept nice and clean. Thinner liners will need changing and washing more frequently.

Washing fleece liners

The one thing you do need to consider when choosing fleece liners is the fact that they will need washing. You’ll need at least 2 sets of fleeces so while one is being washed you have another set for the cage. Make sure you follow the washing instructions that come with them to ensure you don’t shrink them beyond what is expected.

You can find out lots of information on how to wash your fleece liners and keep them smelling fresh and clean here... 

We recommend the following fleece liners:

GuineaDad sell fleece liners in standard C&C cage sizes (2x1, 2x2, 2x3 and 2x4) and they can be combined for larger cages. They also make them especially for the Habitat cage size. We have found these to be great for absorbency and they also have a great design feature - a pocket at one end which your guinea pig can snuggle into and hide! These absorbent fleece liners come in a range of about 7 solid colours.

Handmade on Amazon: These come in a large range of sizes for C&C cages in lots of colour and pattern options. They are not as absorbent as those sold by GuineaDad so you may need to change them a little more often and these are not made for the Habitat cage size either so if you have a Habitat you’d be best with the GuineaDad cage liners.  An advantage is they are quite light in weight (lighter than GuineaDad liners) so don’t take long to dry after being washed. You can view the solid plain colours here or the multi-patterned fleece liners here...

FAQs about bedding

Can I use straw instead of hay?

Many people are not aware of the difference between straw and hay. Straw has hard stems so is more likely to cause an eye injury as your guinea pig nestles into it. For this reason straw should NOT be used as a bedding for guinea pigs. It is worth noting that straw is also not edible.

Is sawdust a good bedding for guinea pigs?

Sawdust is definitely NOT a good bedding. It should be avoided at all costs. The reason is that sawdust is “dust”. Any guinea pig bedding should be dust-extracted to prevent respiratory illnesses for your pet so you should NEVER use this in your guinea pig’s cage.

Are cedar wood shavings safe?

Cedar wood shavings are unsafe due to the high levels of aromatic oils. Even kiln-dried cedar isn’t safe so if you’re using wood shavings stick to then kiln dried wood shavings we recommend

Is coloured or fragranced bedding a good idea?

Some paper or wood-pulp based bedding can be purchased in various colours and although they usually describe them as non-toxic, we always recommend natural as we believe as natural as possible is always best for your pets.

The same goes for fragranced bedding - always try to buy as natural as you can. Although we like lovely colours and fragrances, your guinea pigs will prefer something closer to nature.
