Why Do Chinchillas Eat Their Babies? Understanding the Surprising Behavior

Chinchillas are small furry animals that are popular as pets due to their cute appearance and friendly nature. However, it is not uncommon for chinchillas to eat their babies, which can be distressing and confusing for their owners. In this blog post, we will explore the reasons why chinchillas eat their babies, the factors that contribute to this behavior, and how to prevent it.

Chinchilla Reproduction and Gestation

Before diving into the reasons behind chinchilla infanticide, it is important to understand their reproductive cycle. Chinchillas are seasonal breeders, with their breeding season running from November to May. Female chinchillas have a gestation period of around 111 days, during which they can give birth to litters of up to six babies, known as kits.

Reasons Why Chinchillas Eat Their Babies

Infanticide is common among different species of animals, and chinchillas are no exception. The reasons why chinchillas eat their babies can vary, but it is often due to a combination of factors. One of the main reasons is stress and trauma. Chinchillas that are stressed or have been traumatized may eat their offspring as a way of coping with their environment. This can happen if there is a sudden change in their living conditions, such as a new pet introduced into the household or a change in their diet.

Another reason why chinchillas may eat their babies is due to natural selection. In the wild, chinchillas are exposed to predators and other dangers that threaten their survival. By eating their young, they can ensure that only the strongest and healthiest offspring survive. This behavior has become ingrained in their genetic makeup and can still manifest in domesticated chinchillas.

Baby-eating as a Response to Stress and Trauma

As mentioned earlier, stress and trauma can trigger chinchillas to eat their babies. This can happen if the mother feels threatened or uncomfortable in her environment. For example, if there is too much noise or movement in the household, it can cause the mother to become stressed and eat her young. Similarly, if the mother is not receiving enough food or water, she may feel the need to sacrifice her young to survive.

In some cases, a mother chinchilla may eat her babies if she senses that they are not healthy or viable. This may happen if the kits are born prematurely, have birth defects, or are weak and unable to nurse properly. In these cases, the mother may view eating her young as a way of preventing them from suffering.

Natural Selection and the Survival of the Fittest

In the wild, natural selection plays a significant role in the survival of different species. Chinchillas are no exception, and their behavior of eating their young can be traced back to the need for survival. By eating their weaker or sicker offspring, the mother chinchilla can ensure that only the healthiest and strongest kits survive. Over time, this behavior becomes ingrained in their genetic makeup and can still manifest in domesticated chinchillas.

Preventing Chinchilla Infanticide

While chinchilla infanticide can be distressing for their owners, there are steps that can be taken to prevent it from happening. One of the most important things is to ensure that the mother chinchilla is in a stress-free and comfortable environment. This means providing her with a quiet and secluded space where she can nurse her young without any disturbances.

It is also crucial to provide the mother with a healthy and balanced diet, as malnutrition can be a contributing factor to infanticide. Additionally, it is important to monitor the health of the mother and her young regularly, and seek veterinary care if necessary.

Finally, it is essential to breed chinchillas responsibly to prevent infanticide. This means only breeding healthy and genetically sound chinchillas, and avoiding inbreeding or breeding too frequently.

Breeding Chinchillas Responsibly

Breeding chinchillas responsibly is crucial for their health and well-being. It is important to only breed chinchillas that are healthy, free of genetic defects, and have a good temperament. Additionally, it is recommended to avoid inbreeding, as this can increase the risk of health problems and infanticide.

If you are considering breeding chinchillas, it is important to do your research and consult with experienced breeders. This will ensure that you are providing your chinchillas with the best possible care and preventing any potential health problems.


In conclusion, chinchilla infanticide can be distressing for their owners, but it is a natural behavior that is deeply ingrained in their genetic makeup. Understanding the reasons behind this behavior and taking steps to prevent it can help ensure the health and well-being of both the mother and her young. By breeding chinchillas responsibly and providing them with a stress-free and comfortable environment, we can help prevent infanticide and ensure that these adorable little creatures thrive.
