1. Hamsters Eat Own Babies

Yes, the mother hamster may eat her own babies. It is totally normal and can happen for the reasons below.

Hamsters Eat Own Babies

Weak Baby

Hamster mothers seem to maintain the natural rule of “Survival of the Fittest.” In general, they give birth to more than four babies at a time.

And by nature, all pups do not have the same strengths to survive. To ensure the survival of the strong ones, hamster mothers kill weak babies and eat them.


It is undeniable that babies come with greater responsibilities. When the hamster mother becomes overwhelmed by her responsibilities, she eats some of the pups to relieve herself of the burden.

Unfamiliar Situation

It is applicable to first-time mothers. By giving birth for the first time, some of them become confused with the “what to do” context and eat the litter.

Unwanted Size

If a hamster delivers an above-average-sized pup, it may be shocked and reject the pup. As a result, the mother eats that one.

Stress over Food and Cage Space

As mentioned earlier, hamsters may give birth to more than six pups at a time. They may find the supplied food is not sufficient and eat some of the babies to reduce pressure on the food supply. 

Space inside the cage is also an issue. If the mother believes there is insufficient space for herself and the babies, she will eat some of the pups to ensure there is enough space for everyone.

Gone of Mother-Feel

Hamsters’ brain size is as small as their body. Their memory is also very weak. After a few days of giving birth, they forget motherhood and consider the newborns as rivals. This situation leads to the hamster mother eating some babies.

2. Eating Another Hamster’s Dead Body

Eating Another Hamster’s Dead Body

Yes, hamsters also eat other hamsters’ dead bodies. It is also natural and has a scientific explanation. The following are the reasons:

  • Not to attract predators but to save themselves
  • By eating dead bodies, hamsters restrict the spread of diseases

3. Fighting with Other Hamsters

Hamsters’ cannibalism also directs them to fight against each other. Sometimes, those fights conclude in death. Later on, to do the “clean up” task (to avoid predators and restrict the spread of diseases), the living hamsters eat the dead hamster.
