How to Choose the Right Type of Cotton Wool for Hamster Bedding

When choosing cotton wool for your hamster, it is important to choose a free product from chemicals and pesticides. Look for 100% natural cotton wool or organic cotton wool if possible.

Cotton wool should be soft and fluffy and should not have sharp edges. Avoid using cotton balls, as these can be dangerous for hamsters to eat.

Risks of Using Cotton Wool for Hamster Bedding

Hamsters are known for their digging and chewing habits, and they may try to eat the cotton wool. If swallowed, cotton could cause:

An Obstruction in the Digestive Tract

The obstruction is the main risk of using cotton wool for hamster bedding. If your hamster swallows a large amount of cotton, it could obstruct the digestive tract.

This is a serious condition that can be life-threatening.


Cotton wool can also cause constipation if swallowed. The fiber will absorb water from the digestive tract, making it difficult for your hamster to pass stool.

A hamster suffering from constipation will show signs of discomfort, such as straining to defecate. Constipation caused by internal blockage will lead to swelling of the abdomen and may be accompanied by vomiting.

If you think your hamster is constipated, contact your vet for advice.


If your hamster’s cage is not clean, the cotton wool could become contaminated with bacteria. This could lead to an infection if your hamster ingests the bacteria.

It is important to monitor your hamster closely when using cotton wool as bedding and remove any pieces chewed or eaten.

Tips for Using Cotton Wool Safely

To reduce the risk of your hamster swallowing cotton wool, it is important to:

Provide Plenty of Hay

Hay is an excellent source of fiber for hamsters, and it will help keep the digestive tract healthy.

Provide Plenty of Fresh Vegetables

Fresh vegetables are a good source of water and fiber, and they will help prevent constipation.

Avoid Using Cotton Balls

Cotton balls can be dangerous for hamsters to eat, so it is best to avoid them.

Other tips include:

  • Choose a high-quality product that is free from chemicals and pesticides.
  • Make sure the cotton wool is soft and fluffy, with no sharp edges.
  • Monitor your hamster closely and remove any pieces that have been chewed or eaten.
  • Keep the cage clean to prevent the cotton wool from becoming contaminated with bacteria.

Features of the Right Type of Hamster Bedding


The bedding should be soft and comfortable for your hamster. If the bedding is spikey, the hamster may hurt itself.

Hamsters are known to be very active and playful, so comfortable bedding is key for a good night’s sleep.


The bedding should also be absorbent to keep the cage clean and dry. A wet cage is uncomfortable for your hamster and can also lead to health problems.


Breathability is important to prevent ammonia build-up, which can be harmful to your hamster. Ammonia is a gas that is produced when urine breaks down.

If the bedding is not breathable, the ammonia can build up and cause respiratory problems.


The bedding should be non-toxic if your hamster decides to nibble on it. Some beddings are treated with chemicals that can be harmful if ingested.


Hamsters are very sensitive to smell, so the bedding should not have a strong scent. A strong scent can be overwhelming for your hamster and may cause respiratory problems.


The bedding should be safe for your hamster to eat as they will try to nibble on it. Some materials such as cotton wool can cause problems if ingested, so these should be avoided.

Instead, look for softwoods such as Aspen.

Ease of Cleaning

You will need to clean out the hamster cage regularly to prevent smells and disease. Some bedding materials, such as newspapers, can be difficult to clean.

Look for bedding easily removed from the cage, such as wood shavings.


The price of the bedding will vary depending on the type and quality. Some beddings are more expensive than others, but that does not necessarily mean better.

It is important to find a balance between price and quality.

What are the Alternatives to Cotton Wool for Hamster Beddings?

There are some alternative bedding materials that you can use for your hamster. These include:

Wood Shavings

Wood shavings are a popular choice as they are absorbent, breathable, and easy to clean. They are also relatively cheap and last a long time.

Shredded Paper Towels

Shredded paper towels are another absorbent option that is easy to clean. However, they are not as breathable as wood shavings and can be more expensive.

You can customize the absorbency of shredded paper towels by adding more or fewer layers and using colored napkins.

Aspen Bedding

Aspen bedding is softwood that is safe for your hamster to eat. It is also absorbent and breathable. However, it is more expensive than wood shavings.

Carefresh Bedding

Carefresh bedding is made from recycled paper and is absorbent and breathable. It is also relatively cheap and easy to clean. However, it is not as durable as some of the other options.

Fabric Scraps

You can also use fabric scraps as bedding for your hamster. Fabric is absorbent and breathable, and it can be easily cleaned.

However, it is not as durable as some of the other options. Knit and fleece scraps are the best choices when it comes to fabric. Fleece is great when it is cold as it provides insulation.
