This is a rather important article for owners looking to purchase a guinea pig cage, so make sure to read this thoroughly before shopping. Remember, this is your pet’s new home, where they will be spending most of their time. Correctly setting up your guinea pig cages will ensure a happy guinea pig, which ultimately leads to a healthy and long-living life.
We cover everything from cage size to tips for making your guinea pig’s enclosure fun. Guinea pig’s aren’t the highest of maintenance compared to other pets, but it is still crucial to provide them with enough space, fun toys, and high-quality environmental items.
Finding the Perfect Cage Size
A common mistake that many owners make in this early step of raising their guinea pigs is finding a proper sized cage. A lot of people do not realize that a baby guinea pig can potentially grow much larger because of their proneness to becoming overweight. Always keep in mind that even though your pig may be small at the moment, you need to purchase a cage that will fit them comfortably throughout their adulthood.

Most cages sold at commercialized pet stores, including PetSmart and Petco, are not the recommend size for guinea pig. Ofte, cages are simply marketed as “small animal enclosures” in an effort to reach a wider consumer base. But a cage for a hamster will certainly not do for a full-grown guinea pig.
Those cages will do for a baby, but certainly not an adult. Simply ask what they would recommend for an adult guinea pig instead. Usually, the bigger the better, as long as you have the budget and space at home.
Remember, guinea pigs love exploring, so they will always appreciate extra space to call their own.
Quick Little Formula
We have seen information circulating the web that 2.5 square feet is enough room for one cavy. However, this is not true. Try to aim for 7.5 square feet for a single guinea pig.
We want to reiterate how crucial this is because you need a cage with enough space for them to run around and exercise, even as an adult. Without the proper daily exercise, you can potentially cut their lifespan by a few years. And, we wouldn’t want that would we?
Guinea Pig Cages for Two or More
Of course, the more pigs you decide to bring home, the bigger the cage should be. If you’ve read the section above, this should be common sense. For two, you should try to aim for 10.5 square feet minimum of space to allow plenty of room for each to claim an area of their territory.
This is especially important if you choose to bring home two male guinea pigs. Without a large enough space, they could be fighting for territory all the time, which can potentially lead to one getting injured. Obviously, pay attention to different guinea pig noises to determine if they’re having fun playing or fighting/in distress.
If you’re going to put two females in the same enclosure, then space will not be as big of an issue. Because of their passive nature, they will tend to fight less over territory. However, I would still recommend a large space for them to run around and be active.
The Bedding
There is a lot of misconception on the web when it comes to guinea pig bedding. In fact, a lot of products we see being sold for bedding can actually be harmful to them. We’ll start with products to avoid.
Pine and cedar shavings are a big “NOPE” when it comes to bedding. These products are poisonous to the pigs and can actually cause problems with their respiratory systems. Although sneezing and coughing will happen from time to time, these shavings can sometimes cause uncontrollable amounts of coughing/sneezing. If that happens, switch out the bedding to see if it ceases. If not, take them to the vet because it might be something more serious.
An inexperienced pet shop salesperson might recommend pine and cedar as popular choice because of their odor-neutralizing abilities. Don’t go for it! But don’t use them at the risk of your pet’s health.
The most futile thing you can use for bedding may be straw. Not only is it ineffective in odor-control, but it also doesn’t absorb droppings at all. Guinea pig cages are already difficult enough to keep clean, and this will ensure your guinea pig is living in a dirty environment, which will surely take a toll on health in the long run.
What we would recommend is Timothy hay. Yes, the same hay we suggested as the primary source of a guinea pig’s diet. If you decide to go with this, make sure to change out the hay quite often so that they don’t consume soiled hay. Also, you can train them to not eat their bedding hay by providing a hayrack with pellets mixed in.
Guinea Pig Cage Supplies
Don’t forget to add a water bottle! Got to stay hydrated! It’s quite common for guinea pigs to play around with their water bottle, so make sure the water is clean by refilling it once a day. Do not give them a small water bowl as their water supply. From personal experience, they’ll usually flip them over and cause a mess.
We recommend giving the water bottle a thorough cleaning at least twice a month. Bacteria love damp surfaces, and can see the water bottle as a breeding ground.

You should also provide great guinea pig toys for their amusement. Toys can include obstacles that promote exercise or give them entertainment. However, keep all obstacles and toys off to the side to ensure they have plenty of space to roam around and get a good workout. Feel free to add terrain objects like rocks if space permits.
It’s a known fact that a guinea pig’s front incisors are always growing. Throw in a few chew toys, as it allows them to trim their teeth throughout the day (and night).
Other Recommendations
Do not pick a cage with wire flooring, as it can be quite uncomfortable for your pigs and difficult for cleaning. If possible, purchase a cage with a bottom tray so you can easily slide it out to swap out bedding.
Having a large door is also a great idea as it allows you to have easy access to your pigs anytime. There may be emergencies, such as fights or seizures, where you need to quickly get to them.
Home Sweet Home
Just follow these tips and you’ll have the perfect environment for any breed of guinea pig! But remember that these creatures of habit do not like sudden change. So, once you’ve found something that works, we would suggest sticking to it. No more drastic changes.

Thank you for such an informative read. What would you suggest to use for litter. I’m babysitting my daughter’s guinea pig and I would like to introduce litter. This little man is about two years. His mate died and that concerns me as he would be lonely. I’d appreciate your advice. Regards Pauline
You want to use a litter box for your guinea pigs? Usually we just let guinea pigs go in their cage and clean up afterwards. It would be impressive if you could train a guinea pig to use a litter box.
I trAined my guinea pig to use a litter box I used a plastic tray from harbor freight for nuts and bolts so it was low enough to get in and out easily and filled it with paper bedding and put it in the corner by her water and it worked great she was trained in a few days and made cleanup fast and easy
I would like to get a second Guinea pig, I just need some help on if I need a new cage or the one I have is good enough for two, the cage I have is called All Living Things Duel Level Ramp Habitat Small Pet, if someone could give me some help with this I would really appreciate it thank you
Does that guinea pig cage have around 10 square feet of cage room for the two guinea pigs?
The cage my new piggie came in is wayy to small but she’s still very scared and skittish(hadn’t been handled much) when would be a good time to move her to a bigger cage? I’ve only had her a couple days. Thanks!
The sooner you move them to a bigger cage, the better. There will come a point when your guinea pig becomes comfortable around you and its cage. At that point, the bigger cage is necessary. If your guinea pig is scared right now, you can always get a big cage with a few igloos for the guinea pig to hide in (thus, feeling “safe”)
Personally I’d change to the new cage ASAP. Do it when you are doing a full clean of her/his cage. You can set up the bigger cage the way you have the current one so it isn’t as stressful for your shy Piggy!

Thank you.

Do I need more than one water bottle if I have two Piggies?
yes
Do you have to use timothy hay products or can you use felt or soft cloth that absorb
I have two female guinea pigs in one cage and every time I go to clean their cage it gets wet after five days. But the bedding I get is Care Fresh and it’s supposed to last up to ten days. Can someone help me by telling me what to do as far as bedding for two guinea pigs in a cage. Thanks!
Hi Jane,
Are you putting anything under the bedding, or is it bedding straight onto the bottom of their cage?
I suggest either using puppy pads, whelping pads, or even just some newspaper. Lay this down first, then put the care fresh on top of it. You should have at least one inch covering the bass. You may also want to look at even putting cat litter under the care fresh but please do check that it’s 100% safe for piggies first. I suggest going with recycled paper and fibers and to stay away from any salts/crystals. Hope this helps!
My guinea pig has a fleece liner for bedding. Is that safe?
Hi. I was just wondering….. if you had any mixes of fruits or vegetables that you would recommend worked for you. this was very helpful. I wasn’t sure why they mixed hay with litter things but now i know thanks
Thanks for letting me know that it would be wise to not choose pine and cedar for your guinea pig’s cage liners since they increase the risks of them developing respiratory problems. I recently got a guinea pig, and I wanted to get him beddings for his cage, so I was thinking of going for faux fur. I’ll have to contact my vet first if it’s okay before I look for pet supplies stores that sell faux fur cage liners.
