In short, big hamster cages are the best houses for your hamsters. From the expert advice, we can conclude that you should aim for a minimum of 288 square inches or 24 inches by 12 inches by 12 inches. Remember that the bigger the cage, the more room your hamster will have to be happy and active.

Signs that indicate your hamster’s cage is too small

Hamsters can be very unhappy when they have a small-sized cage. So, what are the indications that you need to have a bigger cage?

Your hamster is constantly bar biting

Extreme bar biting is a huge sign that your pet is unhappy. If you find that they are trying to escape or biting the cage continuously, then note that it is very small. In such a situation, the only solution is to get a larger cage.

Displays cage aggression

As a hamster owner, you should know your hamster’s normal and abnormal behaviors. If the animal exhibits very aggressive behaviors, it may not be happy in its cage. The cage aggression indicates that it is time for a change.

Your hamster is lethargic

Hamsters will be energetic and playful when happy. They like exploring their cages, moving around and using wheels. However, if your hamster is only drinking, eating and sleeping, there is a high chance that it is unhappy and you need a bigger cage.

Cage climbing behaviors

Excessive cage climbing is a sign that the cage is too small and needs an upgrade. It shows that your playful animal is highly bored. Therefore, you need to pay more attention to how your hamster behaves to determine whether it is time to get a bigger hamster cage.

How much is a hamster cage?

In the market, you will find that hamster cages are available at different costs. The varying prices are because of factors such as size, material used, design and available accessories. Cheap hamster cages can go for as low as $25, while others can go for more than $200.

The cost you will pay for your cage will depend on your preferences. You can also consider a DIY hamster cage. The DIY cage will instruct you to build your hamster’s cage using readily available materials. You only need to prioritize the cage size for your animal’s comfort.
