How Big Should a Hamster Cage Be? [Helpful Guide]

Hamsters aren’t your typical kind of lazy-bone pets in the United States of America. Despite their tiny sizes, hamsters are energetic, requiring large spaces to play, burrow, and explore. Now, since you’ll have to keep your furry friend in a cage, have you been wondering how big it should be?

A standard hamster cage should be 576 square inches (3,616 square cm), which is the standard according to the Humane Society of the United States (HSUS). However, different individuals and organizations have varying guidelines on how big an ideal cage should be.

The rest of this article will discuss a few topics related to this question in detail. I’ll address the best size for a hamster cage, how the cage size affects a hamster’s well-being, and ideal hamster cage samples. You don’t want to miss out on anything, so read on.

What Is the Best Cage Size for a Hamster?

The best cage size for a hamster is at least 30 x 30 x 15 inches (76 x 76 x 38 cm), but the bigger, the better. Note that the hamster cage size may also depend on a few factors, including the hamster species, availability of space to keep the cage, and number (or type) of accessories.

The rule of thumb is to provide the largest space possible to make your hamster happy.

It can be daunting to settle on specific dimensions for your hamster’s cage size, as there are numerous opinions on the topic. Most animal welfare groups recommend that a hamster’s cage be at least 450 square inches (2,903.22 square cm).

However, Hamster Central forum members argue that the size shouldn’t be less than 465 square inches (2,999.99 square cm) for the floor space.

Now, the best cage size is one that allows a hamster to run, burrow, explore, and make its toilet. If you think about it, a cage can’t compare to a hamster’s natural habitat (despite the species), as these small creatures create long burrows in the wild.

Moreover, due to their dynamic nature, you need to keep them in a large space that’ll help them burn their massive energy.

Different Hamster Species May Require Different Cage Sizes

19 hamster species exist, although only four are kept as pets. The Syrian (or golden) hamster is the most popular pet hamster. All the other three are dwarf breeds, including the Campbell’s, Russian, and Chinese hamsters.

Since Syrian hamsters are bigger and love roaming around in large spaces, you can have a cage measuring 600—900 square inches (3,870.96—5,806.44 square cm).

Moreover, this hamster breed is solitary, meaning it’ll thrive better when living alone. But that shouldn’t stop you from keeping your paw-friend entertained, and you can have several accessories in the cage.

Despite being smaller, dwarf hamsters also require ample living space. So, they can do well in a cage measuring 450—700 square inches (2,903.22—4,516.12 square cm). Like other species, they also need toys and accessories, including wheels, bedding, tunnels, and tubes.

Dwarf hamster species are more social than their Syrian counterparts. Therefore, you can keep them in pairs or small groups. But this will also require you to increase their cage size, ensuring there’s enough space for everyone.

A hamster cage is a home within a home. So, you need to find an ideal space to place the cage—away from direct sunlight, predators, and your bedroom (hamsters are nocturnal). The available space in your house will determine how large the hamster cage will be.

A larger cage will be the best option if you have ample space. Plus, you can decide to set up a continuous one with tunnels, ladders, a wheel, nest boxes, and other interactive toys. But if space is a concern, opt for a tank (with a good depth), as it’ll provide enough room for the hamster’s bedding and accessories.

You Can Include More Toys and Accessories in a Big Hamster Cage

As I’ve mentioned, hamsters are active (especially at night) and require interactive toys to keep them entertained.

Now, if you want your furry friend to exercise maximally and remain stimulated, having several accessories in its cage will be an added advantage. But this will require sufficient space to ensure that these extras don’t crop up and reduce your pet’s nesting area.

How Does Cage Size Affect a Hamster’s Well-Being?

The cage size can help maintain the hamster’s well-being. Some research findings have shown that large hamster cages can help minimize chronic stress in the animal. The evidence correlates with what we know about hamsters: they’re adapted to extensive areas.

Therefore, a small cage would be unfavorable and have adverse effects on the hamster.

Research on the relationship between hamster behavior (and well-being) and cage size is limited. But some researchers have studied this topic, confirming what animal welfare organizations and experts recommend about hamster cage sizes—the larger, the better.

So, let’s have a look at two of these studies.

In the first study, Gernot Kuhnen examined the effect of cage size and enrichment on core temperature and febrile response (fever) in golden hamsters. The hamsters were kept in standard-sized cages and then transferred to differently-sized and enriched cages.

However, the cages had smaller dimensions (200, 363, 825, and 1,815 square cm or 31.00, 56.26, 127.87, and 281.32 square inches) than the standard hamster cage sizes.

Kuhnen induced fever in the hamsters to demonstrate how chronic stress weakens an animal’s immune response. And hamsters in smaller cages exhibited a lower febrile response than those in larger cages, indicating a weaker immunity due to chronic stress.

Therefore, findings from this study showed that small-sized cages increased chronic stress in hamsters and affected their thermoregulation.

Another study by the Animal Welfare of England observed the behavior of golden hamsters kept in four differently-sized cages (1,800, 2,500, 5,000, and 10,000 square cm or 279.00, 387.50, 775.00, and 1,550.00 square inches).

Video recordings showed that the hamsters in smaller cages gnawed more on wires and tended to look for extra space on the roofs. Contrastingly, those in the largest cages (10,000 square cm or 1,550.00 square inches) had less gnawing, demonstrating better welfare.

So, the researchers concluded that hamsters in smaller cages exhibited higher stress levels than those in larger cages. Though gnawing is a natural hamster behavior, prolonged and frequent gnawing could mean that they weren’t comfortable in the limited space.

On the other hand, the hamsters in bigger cages made maximum use of the space, depicting that they could do well in a larger cage.

In both studies, cage size impacted the well-being of golden hamsters. However, these findings weren’t void of limitations.

For instance, the second study didn’t consider other factors affecting a hamster’s welfare, including cage enrichment and the hamster species.

Moreover, placing the small cages next to each other would have increased the hamsters’ stress levels since golden (Syrian) hamsters are solitary.

What Is the Best Cage for a Hamster?

Apart from sizes, hamster cages are available in different types and designs. With the numerous varieties in the market, it can be challenging to settle on. However, the perfect choice of hamster cage will depend on several factors.

The best cage for a hamster is a spacious cage made of high-quality material, well-ventilated, and easy to clean. Moreover, a hamster cage should be chew-free and well secured, as most hamsters are escape artists.

Several brands that sell some of the best hamster cages include Savic, Ferplast, Midwest, and Kaytee CritterTrail.

Since hamster cages come in different sizes and designs, you can choose one depending on your furry friend’s requirements or your taste. But it should also resonate with the available space in your home. Additionally, the cage size should allow you to add accessories to keep your hamster entertained.

Here are different types of hamster cages and their properties:

  • Wire/mesh cages: contain a plastic or metal base surrounded by wire or mesh. They’re popular due to good ventilation and high-quality materials. Plus, they’re easy to clean. But the shallow base isn’t ideal for hamsters; hamsters prefer deep bedding (or substrate layer). Also, hamsters love chewing on the bars, and they may even escape if the spaces between them are big (mostly over 1 inch or 2.54 cm).
  • Tanks with cage toppers: are alternative cages entailing a glass or plastic tank with a metal topper. Unlike wire cages, tanks have a deeper base and chew-proof materials. They’re also well ventilated and easy to clean. Most of them comprise two sections, making them ideal for installing interactive toys such as ladders and tunnels. Therefore, they make good hamster cages if they’re large enough.
  • Vivariums: are typically cages that somehow resemble aquariums or terrariums. So, they’re made of glass, with plastic, metal, or wood frames. However, you can customize them by having a mesh upper part to improve ventilation. Unlike the other cage types, vivariums are harder to clean but are larger and have deep bases to allow burrowing.

Now, let’s look at some of the best cages you might consider buying for your hamster:
