Hamsters are known for their friendly and playful personalities. However, they’re not always as friendly as they appear to be.

In fact, some hamsters have been known to eat their hamster friends! However, this behavior is rare and typically only occurs in young hamsters raised in small cages.

Hamsters often eat each other when they are caged together.

While in the wild, hamsters eat insects and other small animals. Once they end up in cages, however, they develop a taste for each other’s flesh.

They usually start by eating the paws and tails of their cage mates, but they will move on to eating each other’s heads and internal organs.

Do Hamsters Cannibalize?

Most hamster breeds do no cannibalize one another; however, some do.

However, a variety of factors may cause this behavior; including if their diet changes, if new hamsters are added to the cage or if their mates are taken away.

Almost all dwarf hamster species will cannibalize if they are caged together because their natural diet includes insects and other small animals which they won’t find in their cages.

In contrast, Syrian and Chinese hamsters usually won’t eat each other because they’re fed a pelleted diet which doesn’t cause them to be territorial.

Inappropriate Cage

Choosing the appropriate cage arrangement for your dwarf or Syrian hamster is very important to prevent cannibalism from occurring.

Hamster cages come in a variety of materials, however wire is the best material to use for dwarf or Syrian cag.

Protection of Their Territory

Despite having a plenty of nutrients and shelter, some hamsters become territorial and feel the need to protect their territory.

While being territorial isn’t necessarily a bad thing in animals, it’s often undesirable in our pets.

Cannibalism is one of the territorial characteristics that may occur if your hamster shows territorial behavior.

In some cases, this behavior may be explained away by a disrupted diet or roommates. Hamsters are social creatures that need company, stimulation and interaction if not provided care by humans.

If their cage is too small, they may eat their hamster friends out of loneliness and boredom.

Unbalanced Diet

You may feed your pet hamster a nutritionally balanced meal; however, this doesn’t mean he or she will eat it entirely.

Broccoli, kale, cucumber, celery, carrots and other vegetables that are high in fiber may stimulate your rodent to hoard the food and not eat it.

You may also give your hamster treats like CheeriosĀ®, birdseed or dried fruit.

When you feed hamsters a monotonous diet consisting exclusively of pellets (or seeds), they may become bored and start eating each other out of boredom.

Inadequate Food

Even if you have docile and calm hamsters at home, they may still start eating each other if you try to feed them certain foods.

Foods like corn, Indian corn and popcorn can be harmful to hamsters. However, hamsters may also show cannibalistic tendencies simply because of food allergies. Do Hamsters Like Corn?

How to Avoid Cannibalism in Hamsters

Keep an Eye Out for Newborn Hamsters

After a mother hamster gives birth, keep an eye open for newborns in the nest.

They will spend a lot of their time hiding in the nest and may accidentally be eaten by their siblings.

Separately House Your Hamsters

To minimize territorial conflicts, keep your Syrian or dwarf hamsters in separate habitats to avoid cannibalism.

While one hamster may eat the hammie next door, the hamster next door may eat the hamster to his left.

Why Do Hamsters Eat Their Own Babies?

Threat From a Male Hamster

Male hamsters are more aggressive than females and may attack and kill babies from female cages.

All they are concerned with is protecting their mates and babies.

A male hamster generally annoys the innocent infants while trying to assert his dominance over them.

Change in Scent

Scents are used by rodents to mark their territory and defend it against invaders.

While caring for their young, hamsters will scent-mark the area around the nest using urine, feces and pheromones.

If a human touches one of the newborns, the mother’s scent will change to that of the human and the newborn will get confused.

The hamster will smell the change and believe that it’s an intruder and try to defend its nest by killing it.

To Safeguard the Live Babies

If a wild hamster gives birth to numerous kids and one of it is injured or sick, the mother hamster will usually keep feeding it as long as it’s alive.

However, if one of her babies dies or is injured, the mother hamster will bury it or leave it nearby for other rodents to eat.


Hamsters experience a great deal when giving birth, especially when taking care of a large number of pups.

While hamsters can handle the stress of parturition and raising a litter, excessive stress may cause them to neglect their babies or even eat them by mistake.

Environmental stressors for hamsters include loud sounds, bright lights and moving objects.

Dietary deficiency

Hamster foods may influence the behavior of mothers and their offspring, especially if their diets are lacking important nutrients.

When hamsters are fed diets deficient in protein, calcium, vitamins and other essential nutrients, they may lose their appetites and start eating their own young.

For example, hamsters fed maize will sometimes start eating their own offspring because they lack enough protein from the maize.

Final Words

Cannibalism in hamsters is terrible, but it happens more often than you may think.

A human may forget to clean a toilet, which can cause a hamster to claw it to death. Other times, a hamster may nibble on a hamster that is sick or dying and die afterwards itself due to stress.

Instead, if you take efforts to limit the risk, you should be able to raise a healthy family of baby hammies.
