Understanding Hamster Motherhood

Hamsters are known for their nurturing and loving nature towards their young. And it is a joy to observe the bond between a mother hamster and her offspring. Hamsters typically give birth to litters of 4-12 babies who are born blind and hairless. 

The mother hamster is incredibly protective of her young and will fiercely defend them from any perceived threats. She will spend most of her time nursing and grooming her babies, making sure they are well-fed and comfortable. 

Hamster Motherhood

As the babies grow and become more independent, the mother hamster will gradually wean them and begin to introduce them to solid food. She will also teach them essential life skills, such as foraging for food and building nests.

While this may seem strange and even shocking, there are various reasons why cute and cuddly hamsters eat their offspring.

Why Do Hamsters Eat Their Babies

Territorial Behavior

Hamsters are naturally territorial creatures, and when they feel their territory is threatened, they may resort to eating their young. This behavior is more common in Syrian hamsters, who are solitary creatures and tend to become aggressive towards their offspring if they feel their space is being invaded.


If the hamster’s cage is too small, or there are too many hamsters in the cage, the mother may feel threatened and eat her young to ensure her survival.

Lack of Nesting Material

Hamsters need a secure and cozy place to raise their young. However, if they do not have enough materials to make a proper nest, they may eat their babies as a way to protect them from danger.

Hormonal Imbalances

Hamsters are very sensitive animals and any changes in their environment or routine can trigger hormonal imbalances. This can cause the mother to become aggressive and eat her young.

Nutritional Deficiency 

If a hamster is not receiving a balanced diet or lacks certain nutrients, such as calcium. They may not have enough nutrients to support the growth and development of their young, leading to cannibalism.

Stress and Anxiety

Hamsters can become easily stressed, especially if they are kept in an environment that is not suitable for their needs. This can cause the hamster to engage in behaviors that are out of character, such as eating its offspring.

Illness Or Disease 

If a hamster is sick or suffering from a disease, it may not have the strength to care for its young, leading to the consumption of its offspring. A sick baby hamster with a bad health condition can suffer cannibalism from the mother.

Sometimes the mother hamster does this to protect other babies from being infected. It’s instinctual for animals to care for only the ones they know will thrive; it’s truly the survival of the fittest.

Change In Scent

Hamsters have a highly developed sense of smell, and if they detect a change in the scent of their young, they may perceive them as a threat and eat them.

Inability To Care For All The Babies

It also happens when the mother hamster births more children than it can care for. Her inability to cater to all will push her to reduce the number by eating some of them.  

The mother does this out of good for the rest of the babies to help them survive, even though it doesn’t look like a kind thing to do. Watch this video to learn why hamsters eat their babies.

Minimize Stress

Handling the mother and her young too much can cause stress, which can lead to the mother eating her young. Limit your interactions with the mother and her babies and be gentle and calm when you do.

Provide Appropriate Bedding
