8 Reasons Hamsters Eat Their Babies, And How To Save Them

It sounds like a horror story, a mother hamster eating her babies. But it can happen, and it’s never fun to watch. There’s a few ways you can save the babies, but you have to be careful. 

You can’t save them every time, but you can still do your best to make sure they don’t end up horribly. There are some reasons though, why the hamster mothers do that. Those are very important to understand, in order to save the babies.

So why do hamsters eat their babies ?

Mother hamsters are not as emotional as human mothers.  There are a few reasons a hamster mother might eat her young, and here they are:

  1. She feels stressed/threatened like if you constantly check on her and the litter
  2. Her personal space in too small, the babies take up too much space in a cage that is too tiny
  3. She is very hungry after giving birth
  4. Accidentally storing them in her cheeks to carry them
  5. Biting them too hard when she carries them
  6. She thinks something’s wrong with them (diseased, or something physical they can’t survive)
  7. You or someone else have touched them (changed their scent) and she doesn’t think they’re hers
  8. Father hamsters are liable to eating their young as well 

These are mostly reasons that can be avoided, or can be worked on so the mother is comfortable. 

Rodent mothers are not the most careful mothers in the first place, compared to other mothers, for example cats or dogs. All animals can eat or kill their young, if they consider something is wrong with them. But rodent mothers, and hamsters are rodents, are much less attached to their babies.

So let’s get into every reason the mother can eat her young, and how you can avoid this from happening, and/or possibly save the babies.

How to save the hamster babies from being eaten

Many times when the mother decides eating her young is an option, there’s not much you can do. But, you can save the babies 90% of the time by not putting the mother in a position where she thinks she needs to eat them.

Here are the most common examples, and how you can save those babies by helping the mother.

Do not stress the mother

This is the major reason hamster mothers end up eating their young. The stress and effort of giving birth, especially her first litter, combined with you checking up on her constantly will annoy her. 

Once you notice the mother is approaching her due date (18-22 days after mating), start giving her much more food than usual, and bedding and nesting material as well.

She will find the most hidden corner, or use her hideout, to give birth, and you must leave her alone during this time. Best to even leave the room. Fortunately it will probably happen at night, when you’re sleeping.

So if you know your hammy is about to give birth, be careful when approaching her in the morning. Do not poke at her or the cage, talk to her, or try to interact with the babies.

Keep her warm and well fed, and make sure she has plenty of quiet and small children or other pets can’t reach her.

Leave food/protein for the mother before she gives birth

If you notice that your hamster has give birth overnight, bring her some protein. This is the food that will help her regain her strength immediately. Something like cooked egg white, or cooked plain chicken is good for your hamster. 

You could leave her pieces of chicken every evening until she gives birth if you want, but it’s best to not give her something that will leave a tasty smell on the bedding right before she gives birth. She might get confused as to which one is chicken and which is her baby. 

So only give her chicken or egg after she gave birth, only  while you can see her. Even if you don’t stay more than a few minutes, make sure she finishes the piece and not the babies. 

In the mean time, continue feeding her through the bars, without placing your hand inside the cage. You can introduce a teaspoon through the bars to give her dry food, or sprinkle some on her food bowl.

She will have a stash of food anyway, but right now would be a good time to give her more. For a list of safe foods you can give your hammy, check out this article.

Give the mother plenty of space, in a large cage

This is again something that will always come up. Space, lots of it, is something that hamsters need. The absolute minimum for a hamster cage is 24 x 12 inches, and about 12 inches tall. That’s 61 x 30.5 cm, and about 30.5 cm tall.

That’s the minimum for a Syrian hamster, and it’s what I’d recommend for a dwarf hamster as well.

A hamster mother giving birth to 6-12 babies at once is going to fill up a cage fast. In those times, even her large cage might seem a bit cramped for her. 

So always get your hamster a large cage, larger than you’d think. Especially if it’s a female you will want to breed later. You can find out more about hamster cages here, since you’ll get a rundown of all cage types and which is best for your hammy.

If you’ve got 2 or more hamsters housed in the same cage, remove the mother-to-be and put her in a different, large cage long before she gives birth. She needs to adjust and feel comfortable in her new home as soon as you put her there, so place some of her old bedding and nesting material in her new temporary cage.

Do not disturb the mother or cage for at least 2 weeks after giving birth

This is because the mother is very tired ans started and jumpy while her babies are still very young. So do not open her cage, or change the bedding, try to put her in an exercise ball or separate her from her babies.

Hamster mothers will do their best to raise and wean every one of their young, but they can scare very easily and end up eating their babies.

This includes feeding the mother as well, feed her through the bars with a teaspoon or sprinkle some dry food onto her bowl.

Do not touch the babies at all until the mother weans them (3-4 weeks)

Touching the babies is a big mistake, when they’re so young. A baby hamster can only be removed from his mother after 3-4 weeks, and can be given for adoption immediately after.

You will notice the mother has weaned them when she pushes them away after they try to nurse from her. In this period it’s important to provide her cage with even more food, since the babies will now need ‘adult’ food, like a food mix or some safe foods from your fridge or pantry.

Touching or handling the babies before they are weaned will make the mother think they’re foreign, and not hers. She will reject or even eat them, so it’s best to wait a few more weeks.

Separate the father from the litter at all times

If the father was in the same cage as the mother, and you didn’t know she was pregnant, remove the father from the cage.

Surprises happen, especially with dwarf pairs, since their sex is difficult to tell sometimes. So you might end up with a male and female pair that will give you a surprise litter one morning.

The father will try to get the mother’s attention, and might eat or hurt the babies while trying to get her attention.

Hamster fathers are not nurturing, and will not tolerate the babies for long, so it’s best to remove him from the cage. If you don’t want any more litters, keep the male and female separate at all times.

Hamsters can mate again, right after the mother gave birth, so keep them apart.

Some things you can’t change or save

Even if you do you best to keep the mother safe, warm, well fed, not stressed, and on her own in a very large cage, she still might eat at least some of her babies.

This is mostly due to accidents, like her biting too had on the baby when she tries to pick him up. Or maybe she stores the baby in her cheeks to move and forgets that’s her baby.

It sounds horrible, but small animals can get clumsy like this too. If this happens, there’s not much you can do. If the baby is not weaned yet, you can not touch it because the mother will reject it and then definitely eat it.

Unless you want to raise the litter on your own, since they are just a few days old. But then they will lack the important interaction they need with their mother, to learn how to ‘be’ hamsters.

This is a very touchy topic, and one I’m not about to breach here. The same goes for hamster mothers who kill the babies on purpose, because they think there’s something wrong with them. Like they might be sick or have something wrong with their body, that only she can tell.

She might kill them if this is the case, because she thinks they will not survive on their own. This is again something that can’t be helped, and it’s sad but it can happen.

How to tell your hamster is pregnant

Maybe you ended up with a pregnant hamster when you bought her from the pet store. Or maybe you notice that one of your dwarf hammies is looking a bit odd. Whatever the case, here is how the pregnancy happens and how you can tell your hamster is pregnant.

First, the pregnancy lasts from 18 to 22 days, time in which the hamster’s midsection will become larger and larger. You will notice she eats much more, and doesn’t exercise as much. She is saving her strength.

She will become more and more irritable as her dues date approaches, and will look for hidden, safe corners n her cage.

At this time it’s best to remover her from her cage mate, and place her in a large cage on her own, with plenty of familiar old bedding and nesting material, and plenty of places to hide.

If you’re not sure if your hamster is pregnant, but she seems to suddenly be a bit larger and is constantly digging and burrowing and building a large nest, best to separate her from her cage mate.

If you’re wrong and she’s not pregnant, that’s okay and you can place her back. But wait for at least 3 weeks after you separate her, to see if she does give birth or not.

About hamster fertility and breeding

Hamsters can breed basically every month. In theory, you can have a new litter every month.

This is because a hamster can get pregnant within minutes after giving birth. The problem with this that the mother will be dehydrated and malnourished, and won’t be able to care properly for her existing litter.

Baby hamsters can mate as soon as their mother weaned them.  That’s around 3-4 weeks of age, so you need to separate the hamsters into male and female cages immediately after this happens. If you don’t, more hamster litters will come in a few weeks.

To figure out which is male and which is female, pick the hamster up, and look at his rear end. In females the genitals are right under the anus. In males, there is a more noticeable space left between them. If you tilt a male a bit back while you told him, you might even notice his testicles around his tail.

This is more difficult with the smaller breeds, so every breed except for the Syrian. And hamsters do not like to be held this much or in that position, so they will squirm a bit. But you must do this to figure out which is which, in order to separate them.

Female hamsters are in heat every few days, during the night, so they can be mated at any point. There is no mating seasons for hamsters, as there is with other animals.

I hope you found out a lot about us hammies here. I know a momma eating her babies is terrible, but it can happen sometimes, and I’m glad you found out how to make sure it doesn’t happen.

Us hamsters grow up fast, so make sure you keep us separated by sexes or we’ll make a whole clan in a few weeks.
