Baby Hamsters Week By Week

It will take up to 5 weeks for a hamster pup to reach maturity.

But what happens in the weeks before?

We’re now going to take a closer look at the life of a hamster pup and everything that happens while it is just a few days and weeks old.

Week One – What Do They Look Like?

The hamster pups are just born and are pink and hairless. They stay close to their mother and don’t move about apart from nursing.

The babies are born with teeth but with their eyes and ears shut.

Towards the end of the first week, they might begin to open their eyes and ears. Other breeds will only do this towards the end of the second week.

Towards the end of the first week, you might begin to see some of their fur growing. But depending on the color of the pup, you might have to wait a little longer to see this.

Do not pet the pups during these early stages.

We know these pets are so hard to resist, but you must!

Week Two – What Do Baby Hamsters Eat?

At around 10 days old, the babies begin to enjoy their first taste of solid food. Put one of the following treats in the cage for them to nibble on.

  • Wheat germ cereal
  • Seeds
  • Cucumber

By the end of the second week, the hamster babies should open their eyes and their ears should open too.

After two weeks, the pups should be able to maintain their body temperature on their own as they will have most of their fur at this point. Do not pet the pups yet.

Week Three – When Should You Separate Them?

Week three marks the end of the hamsters’ baby life as they will by the end of this week start being weaned off of their mother. The young will have started looking for food by themselves at this stage.

At just three weeks old you must begin to separate the males from the females and take all of the young away from their mothers.

At last, you can touch them!

Happy Hamster Litters

What should you know when your female hamster is expecting?

If you’re breeding hamsters for the first time, it is good to know that your females’ behavioral patterns will change just before they give birth. Mother hamsters may become agitated and start hoarding nesting material and food to eat.

Prepare yourself for the very large litter. Hamsters have litters containing 8 to 10 baby hamsters.

These tiny animals will only take 3 weeks to mature and not long after, you will need to put them in separate cages.

To keep your mothers happy, make sure they have enough to eat and drink and avoid disturbing her when she begins to make a nest until she finishes weaning her children.
