How Do Girl Hamsters Get Their Period 2?

Hamster estrous cycles typically last four days and during that time she will produce a thick and persistent discharge which indicates she is in heat. At this point she may become aggressive or nest, hoard food supplies and become nestless.

Look out for signs like an enlarged abdomen and swelling of the nipples; pregnant hammies typically display increased appetite.

Estrous cycle

Female hamsters reach sexual maturity as early as five to six weeks old, and can become pregnant as soon as their first period arrives (typically nightly and lasting four days). While hamsters don’t bleed during their cycles like women do, they can sometimes produce smelly discharge and white discharge during these cycles.

Progesterone hormone helps regulate hamster estrous cycles by being measured in female’s blood. If there is not enough progesterone present, corpus luteum begins to degrade and ovulation begins – during this phase the female will become aggressive and ready for mating; otherwise she will enter another estrus cycle two weeks later.

if they mate during this period, pregnancy will occur and she will begin producing milk and become protective of her eggs, while nesting and hoarding food supplies.

A female hamster in heat will emit an unusually strong scent that can become quite pungent, making her particularly jumpy and sensitive to handling, potentially even biting when picked up by humans. You should never touch her belly while in heat as this could increase stress levels and cause cannibalism.

Even without enough funds to buy male hamsters, there are ways you can still ensure she comes into heat. Many pet stores sell sex hormone injections which will begin the ovulation process and induce females into breeding mode. These hormones may be more costly, but they’re one of the best ways to ensure your hamster enters their estrous cycle and is ready to breed. Please remember, though, this method can be risky and illegal so make sure it’s done under supervision from a vet. Monitor your hamster’s behavior to recognize when she may be entering estrus; she will become increasingly active, agitated and smelly if this is indeed the case. When in estrus, make sure to leave her alone and allow time for her to recover so as to minimize stress levels during this phase of her cycle.


Female hamsters reach sexual maturity around six weeks of age, when their first heat cycle starts, lasting four days and signalling male hamsters that it’s time for breeding. Like human menstruation cycles, an estrous cycle in female hamsters doesn’t involve bleeding during this period, instead secreting white glue-like secretions instead.

Hamster bodies prepare themselves for pregnancy by producing eggs in their ovaries and thickening uterine linings, but if she fails to be fertilized during her estrous cycle she will reabsorb those eggs and shed her uterine lining; triggering another estrous cycle if desired by the owner. This process may continue as many times as desired by their owner.

Once a female hamster begins her estrous cycle, she can become hostile and aggressive toward males, so it is wise to keep them apart until her cycle has completed. An exception could be made if the male has become especially trustworthy to the point that they might allow him into their home cage even while she is in heat.

After successful breeding, mother hamsters will notice their tummies swell up as a sure sign they are pregnant. Five days post-mating they will start having viscous white discharge that should last five days – this is perfectly normal and may contain small drops of blood; though rare it should not cause alarm.

Seeing any yellow discharge should prompt an immediate call to a veterinarian as this could indicate infection and be hazardous to both mother hamster and her young. Stressful environments can also increase stress levels among mothers which is harmful to her pups. You must avoid trying to feel any babies inside her belly as this could prompt early labor which could put their lives in jeopardy as well as endanger the health of her litter.


Contrary to female humans who experience menstruation cycles, hamsters experience estrus cycles instead. These four-day periods last 12 hours each and produce white discharge. If a pregnant hamster develops spots on its uterine lining that could potentially be taken as symptoms of her period but are not considered periods themselves.

Hamsters will start going into heat when they have reached sexual maturity at four to six weeks of age, usually overnight and lasting 12 hours. Keep in mind that pregnancy can occur as soon as 24 hours after entering heat!

Once a hamster enters her estrus cycle, she will release hormones that attract males while also preparing her body for pregnancy by growing eggs in her ovaries and thickening the uterine lining. If she does not mate during this period, however, she will reabsorb those eggs and shed her uterine lining – returning back into estrus two weeks later to try again.

At this stage, the female hamster will become highly anxious and aggressive, and will begin hoarding food and nesting for her young. Additionally, extra protein will need to be consumed so as to support their development within her womb.

An expecting hamster should never be touched; even gently stroking it may cause her great distress, leading to abandonment of the litter or eating of its young. Furthermore, providing clean environments with plenty of bedding should help alleviate stress for both mother and offspring alike. Furthermore, owners should avoid engaging with their cage for several days prior to giving birth so as not to provoke the animal into giving birth prematurely.

Hamsters can have multiple litters over their lifetimes; gestation periods typically last 16-22 days. A female hamster may produce up to three litters in any one year. Breeders should remember that, should two litters occur within 12 months, it is recommended to provide the new born puppies with formula and milk replacer to ensure that both mother and offspring receive sufficient nourishment from each other.


Female hamsters reach sexual maturity around 10 weeks of age, when they begin experiencing estrous cycles similar to what women undergo each month – yet these cycles last four days instead of bleeding like men do! Instead of bleeding though, hamsters secrete a white discharge which attracts male hamsters that then may try mating with them; females typically have their first cycle by then!

At this stage, you may notice some spots on your hamster’s fur or cage as the lining of her uterus breaks down, resulting in spots. You might also observe some blood in her cage as part of the pregnancy process; although small amounts are usually considered normal; any significant amounts could signal serious health concerns like pyometra; so be sure to contact a veterinarian as soon as possible if any significant blood shows up in her cage.

As soon as pyometra, a bacterial infection that affects the uterus, occurs it is critical that your pet be taken immediately to see their vet – this condition could prove fatal if not addressed quickly enough. Common signs include an unusually strong smell emanating from their private area as well as thick white discharge from them – either way time should not be wasted!

When pregnant, your hamster’s appetite will likely increase as she seeks enough nutrients for herself and her offspring. You might also see her gathering more bedding to form a nest somewhere within their cage – all sure signs she’s ready to give birth!

If your hamster has an enlarged belly, this could be a telltale sign of pregnancy. However, if she has not been near any males in the last three to four weeks it’s unlikely she is pregnant – in any event swollen bellies could indicate other medical issues so always consult with your veterinarian first before making assumptions.
