How to Stop a Hamster From Eating Her Babies

By Lisa McQuerrey

When mother hamsters are sick, their space is disturbed or they feel stressed or endangered, they may panic and kill and eat their babies. Keep your newborn hammies safe and their mother happy and you increase the odds for breeding success.

Plan the Breeding Cycle

Carefully planning your hamster’s breeding cycle will yield better reproduction results than allowing hamsters the chance to breed indiscriminately. Don’t house males and females together long term, only put them together for breeding purposes. Once you think your female is pregnant, give her a private cage in a quiet area to build a nest and prepare for her babies. This reduces potential stressors created by cage mates that could make her fearful and prone to hurting her babies.

If you don’t want baby hamsters, make sure you know the gender of hamsters living together and sex and separate male and female babies before they reach [breeding age](http://www.fau.edu/research/vetservices/handout_hamster.php), which is typically about 10 weeks for females, 6 weeks for males.

Only Breed Healthy Females

Female hamsters are best bred in their first year and can typically have about seven healthy litters in a lifetime. Breeding an older or sick hamster or making her have back-to-back litters can create stress. Your mother hammie might be prompted to kill and eat her babies if she doesn’t think she can care for them.

Female hamsters become [fertile](http://www.fau.edu/research/vetservices/handout_hamster.php) again right after giving birth. If a male is in the cage with your female right after birth, he may kill the babies to “free up” the mother for mating.

Create a Serene Environment

Mother hamsters sometimes hide newborn babies in their cheek pouches as a way to keep them safe from perceived harm. Babies can suffocate or get eaten during this period. Make sure your mother hamster doesn’t have any fears to contend with by leaving her and her nest of babies undisturbed for the first several weeks after birth.

Don’t touch baby hamsters! If they smell odd, the mother may panic and kill them.

Be calm, quiet and unintrusive when adding food and water and replacing bedding in a hamster cage. Leave the nest itself undisturbed and just scoop out and replace handfuls of old food and bedding in other areas of the cage. The mother will take care of tidying the nest herself.

Feed Her Well

Place food on the floor near the baby nest so the mother has easy access. She’ll need extra nutrition to nurse her babies. Making sure she is well-fed and hydrated will reduce the potential for killing and eating babies.
