A critical question to ask when you’re getting a new hamster is “What size cage should I buy for my hamster?”
Size is important because hamsters are active pets – especially at night. They like to run, climb, play with their toys, and burrow. All this activity means they have to have space in their cages.
The two key questions to ask about space are “What’s inside the cage?” and “What type hamster do you have?”
What’s inside the cage?
Everything you put inside your hamster cage takes up space. So what goes inside the typical cage?
Exercise wheel: Because a typical hamster can run about 6 miles (9 km) in one night you need to have an exercise wheel for your cage. This can be a freestanding exercise wheel or one of the kind that attaches to the metal bars on the cage. The freestanding wheel takes up space on the floor of the cage. But even the kind that attaches to the wire walls takes up space inside the cage.
Tubes: Another way for your hamster to get exercise is to run through hamster tubes. People even connect a lot of tubes so the hamster has a big maze to climb through. Some tubes go outside the cage so they don’t take up any space inside the cage, but some climbing tubes may go inside the cage and take up space.
Water: Hamsters need water. You can attach a water bottle to the outside of the hamster cage, but its tip still takes up room in the cage. If you don’t use a water bottle you have to have space for a water bowl on the bottom of the cage.
Food bowl: What you feed your hamster goes inside a hamster food bowl. These can be large or small depending on how much food your hamster eats.
Toys: There are all kinds of chew toys and play toys for hamsters. You can also get a hamster house or some people even use the cardboard toilet paper holder. Depending on their sizes, these toys use space in the hamster habitat.
So before you buy your hamster cage, think about all of these items and how much room they will take up in the bottom and along the side of the cage you want. Remember you still need plenty of space for bedding so your hamster has spots to burrow, play, and use as a bathroom.
What type hamster do you have?
The other thing you have to consider when you’re thinking about the size of your cage is the type of hamster you have. The typical Syrian hamster, also called a teddy bear or Golden hamster, is about 5 to 7 inches (13 to 17 cm) long.
Having this type hamster may mean some of the items in your cage will have to be larger. For example, your hammy should not have to bend its back when it’s in its exercise wheel. So you may need a larger exercise wheel in your cage if you have a Syrian hamster. You also have to make sure the climbing tubes you get are large enough for this type hamster to fit through. That means more space for your hamster tubes. Also, because of the Syrians size you have to make sure there’s lots of bedding in the cage so it can burrow.
The typical dwarf hamster such as a Roborovski is smaller, being about 2 to 4 inches (5 to 20 cm) long. But many people keep two dwarf hamsters together in one cage because they get along with each other. That means providing enough space in your cage for two hamsters to run around in.
If you want to breed hamsters you’re also going to need a much bigger hamster cage.
Most people recommend getting a wire hamster cage that is at least 24 inches wide by 12 inches deep by about 10 inches tall (61 X 31 X 25 cm).
If you’re planning on using an aquarium, you will need at least a 10 gallon fish tank, but 20 gallons would be even better.
Smaller cages, that are usually 8 inches long by 12 ½ inches wide by 7-1/2-inches high (20 X 32 x 19 cm) may be adequate for a smaller dwarf hamster. It is too small for the Syrian hamster.
Available larger cages are about 16 inches long by 24 inches wide by 12 inches high (40 X 61 x 31 cm). This size will give your hamster plenty of room to exercise and burrow around inside its cage.
