What Should You Place at the Bottom of Your Guinea Pig's Cage? 9 Smart Tips

The best materials to put at the bottom of a guinea pig cage are ones that are absorbent, soft, and safe. Among these, guinea pig waterproof cage liners provide an added benefit by preventing leaks and keeping the cage's base dry.

Also, an absorbent layer like puppy pads or towels helps a lot! Let's explore ten clever tips to help you create the perfect environment for your furry friend.

#1 Coroplast Sheets

Coroplast sheets, crafted from corrugated plastic, are a popular choice among guinea pig owners.

Here's the kicker: They are not only water-resistant but also extremely durable, providing a long-lasting base for your pet's home.

In fact, the fluted design of Coroplast sheets provides a bit of cushioning, creating a surface that is both firm and comfortable for your guinea pig.

Besides, this is particularly crucial for guinea pigs as they spend a considerable amount of time moving around in their cage.

What's more, Coroplast sheets are easy to clean, allowing you to maintain a hygienic environment for your guinea pig. Simply wipe down the sheets with a pet-safe disinfectant, and you're good to go.

#2 Newspaper

Newspaper is a cost-effective and easily replaceable option for a cage liner. It's readily available and can be swapped out frequently to ensure a clean living environment for your pet.

Always opt for newspapers printed with non-toxic, soy-based ink to protect your pet's health.

This is crucial because guinea pigs have the instinct to chew, and consuming toxic ink can be harmful to them.

Newspapers also double up as an absorbent layer. They can soak up any liquid, including urine, preventing it from seeping through to the bottom of the cage.

#3 PVC Canvas

If you're looking for a more durable and long-lasting option, PVC canvas might be your best bet.

It's strong and can withstand the constant activity of your guinea pig.

While PVC canvas is water-resistant, it lacks absorbency.

This means it should be used with a more absorbent material to soak up any liquids, such as urine.

For a clean and comfortable environment, pair it with newspapers, a mattress, or puppy pads - your pet will love it!

#4 Linoleum

Linoleum is another excellent option for lining the bottom of a guinea pig's cage.

Luckily, this material is smooth, water-resistant, and easy to clean.


However, similar to PVC canvas, linoleum lacks absorbency.

Therefore, it should be used in combination with an absorbent material.

By doing so, you'll keep the cage clean and make it more comfortable for your pet.

#5 Plastic Tablecloths, Shower Curtains, Waterproof Mattress Protectors

These materials might seem unconventional, but they can serve as excellent liners for your guinea pig's cage.

In fact, they are waterproof and relatively durable, making them a good choice for the base of the cage.

But it's important to remember to cover these materials with something safe for your pet to chew on, such as newspaper or hay.

This is because guinea pigs are instinctive to chew, and consuming pieces of these materials can harm them.

Absorbent Materials

Absorbency is a crucial factor in maintaining the cleanliness and odor control of a guinea pig's habitat.

For the best results, focus on materials like mattress pads and towels, newspaper, and puppy pads.

#6 Mattress Pads and Towels

Mattress pads and towels are not only soft and comfortable for your pet but also highly absorbent. They can soak up urine, preventing it from leaking to the cage's base.

Plus, they can be easily washed or replaced, making them a practical and sustainable choice for maintaining hygiene.

#7 Puppy Pads

Puppy pads are designed with absorbency in mind.

In fact, they are great at soaking up urine, keeping the cage clean and odor-free.

But, ensure these are covered with another material, such as newspaper or hay, to prevent your guinea pig from chewing on them.

By carefully selecting the lining and absorbent materials, you can create a comfortable, clean, and healthy environment for your guinea pig.

Remember, the ultimate goal is to meet your pet's needs and ensure their well-being.

#8 Hemp Bedding

Hemp bedding is an eco-friendly and safe option for your guinea pig. This natural material is highly absorbent, controlling odors effectively.

It's also dust-free, which makes it a healthier option for pets who may be prone to respiratory issues. The soft texture of hemp bedding can provide a cozy and comfortable surface for your guinea pig.

#9 Pelleted Paper Bedding

Pelleted paper bedding is another excellent choice for your pet's habitat.

Made from recycled paper, this type of bedding is very absorbent and helps control odors. It's also virtually dust-free, reducing the risk of respiratory problems.

Additionally, it's soft and comfortable, providing a great surface for your guinea pig to move on.

The Essential Role of Guinea Pig Cage Bottom Materials

The materials you select for the bottom of your guinea pig's cage significantly contribute to their comfort, health, and overall happiness.

Here's a detailed explanation of why you should do it.

1. Stability and Traction: The Foundation for a Comfortable Environment

Guinea pigs need a stable and grip-friendly surface for effortless navigation in their cage.

The right materials on the cage bottom ensure your pet can move around easily, promoting their natural behavior of exploration and play.

2. Protecting Tender Feet: A Step towards Health and Comfort

Guinea pigs' feet are delicate and can be easily injured by rough surfaces.

So, a suitable bottom layer in their cage provides the necessary padding to shield their paws from damage, contributing to their well-being.

3. Moisture Management: The Key to a Dry and Healthy Habitat

Guinea pigs aren't typically easy to litter train, making it essential to have absorbent materials at the bottom of their cage.

These materials efficiently soak up urine, helping to maintain a dry and clean environment for your pet.

4. Comfort Assurance: Enhancing Your Pet's Living Experience

Guinea pigs value a comfortable living space. Soft and cozy materials at the cage bottom contribute to a pleasing and inviting environment for your pet, enhancing their cage experience.

5. Odor Control: Maintaining a Fresh and Inviting Cage

Certain materials can develop a strong, unpleasant smell over time. Thus, selecting cage-bottom materials that effectively manage odors ensures your pet's living space remains fresh and agreeable.

6. Hygiene Maintenance: Promoting a Clean and Safe Habitat

The cleanliness of your guinea pig's cage is paramount to their health.

So, the bottom of the cage should be lined with materials that are easy to clean and replace, facilitating effortless hygiene upkeep.

Expert Insights for Choosing the Right Bedding

Expert guidance can prove invaluable when deciding what to place at the bottom of your guinea pig's cage.

Dr. Arman Chen, a Veterinary Surgeon & Practice Manager at Gaia Vets, offers a crucial tip [2]:

"Always try to purchase substrate or bedding that has very little powder or is labeled 'powder-less' [2].

Fine powders from bedding, coupled with inadequate ventilation, are a common cause of respiratory problems we see in small pets, from guinea pigs to chinchillas.

Dr. Chen's advice underscores the significance of selecting bedding materials that minimize dust, helping to maintain excellent air quality in your pet's environment.

Following this guidance, hemp and pelleted paper bedding are stellar choices, aligning with the expert recommendation and offering a safe and healthy foundation for your guinea pig's habitat.

Learning about proper materials for your guinea is great - but what about what NOT to do when it comes to flooring? Let's find out...

3 Things Not to Put on the Bottom of the Guinea Pig Cage

While providing your guinea pig with a comfortable and hygienic living environment is essential, knowing what not to put on the bottom of their cage is equally important.

Some materials may seem harmless, but they can potentially harm your pet. Let's discuss some of these materials.

#1 Unsafe Wood Shavings

Certain types of wood shavings, such as cedar and pine, should not be used as bedding for guinea pigs.

These woods contain phenols, natural compounds that give off a strong smell. While this aroma may be pleasant to us, it's not safe for guinea pigs.

The problem with phenols is that they can cause respiratory distress and liver damage in small animals.

They can also irritate the skin and eyes. Exposure to these shavings can lead to health problems over time.

It's also essential to consider the texture of wood shavings.

Wood shavings can be rough and potentially cause harm to your guinea pig's delicate feet, leading to discomfort or even injuries. Instead, consider safe alternatives like aspen wood shavings or recycled paper bedding that doesn't contain harmful compounds and provides a soft surface for your pet.

#2 Raw Straw

While straw might seem like a natural and comfortable bedding for guinea pigs, it's not recommended for several reasons.

Firstly, straw is harsh and coarse. It can poke and scratch your guinea pig, leading to discomfort and possible injury. Straw can especially be a problem for the delicate areas of a guinea pig, such as their eyes.

Secondly, straw could be more absorbent. This lack of absorbency can lead to a wet and unclean environment, which can promote bacterial growth and cause health problems for your pet.

Lastly, straw has limited nutritional value, so if your guinea pig decides to munch on it, it won't receive the necessary nutrients they need from its diet.

Instead of raw straw, use soft hay instead. Hay is much smoother, absorbent, and provides the necessary dietary fiber for your guinea pig's digestive health.

#3 Unhealthy Paper Pellets

Not all paper-based beddings are created equal. Some paper pellets, especially those made from recycled newspapers, can contain harmful chemicals.

Newspaper ink, particularly in older publications, can contain heavy metals such as lead and other toxic materials that are harmful if ingested.

Although many manufacturers use soy-based inks, verifying this before choosing paper pellet bedding is crucial.

Furthermore, paper pellets may only be the best choice if they are easy enough.

Guinea pigs enjoy burrowing and nesting in their bedding, and hard pellets might not be comfortable for these activities.

They can also be rough on your guinea pig's feet.

When selecting paper-based bedding, opt for one that's confirmed safe for guinea pigs, soft, and absorbent. It should be free of inks or dyes, dust-free, and preferably made from unused paper.

Creating a safe and comfortable environment is crucial for your guinea pig's health and happiness.

By knowing what to avoid, you can make better choices for your pet's cage and provide them with the best care possible.
