Though your female hamster will gain weight once she is pregnant, weight gain alone does not indicate pregnancy. Other indications of pregnancy include nest-building, possible hoarding of food, and signs of aggression as her gestation period progresses. Hamsters reach sexual maturity quickly in life, with some hamsters capable of breeding as early as four weeks old. However, it is generally recommended that breeders refrain from pairing hamsters for mating until five to six months of age.  The gestation period for hamsters varies widely by breed. Syrian hamsters typically gestate for 16 days, while many dwarf breeds gestate for 18-21 days. Roborovski hamsters may gestate for up to 30 days.  Females capable of reproduction will want to mate every four days.  A couple days before your hamster is going to give birth, her stomach will swell to a very large size. However, this may also be an indication of a more serious condition. Swollen abdomens may indicate the presence of a tumor, impending heart failure, liver cysts, or in rare cases Cushing's Disease. If your hamster's belly is swollen, it's best to have her examined by a veterinarian to determine whether it's pregnancy weight or something more serious. It's important that your hamster delivers her babies into a clean environment. In order to ensure that this happens, clean your hamster cage two weeks after your hamster gets pregnant (or when you determine that your hamster is pregnant), and add additional fresh bedding.  Know that, since the mother hamster will not like being disturbed as it gets closer to her delivery date, you may not be able to clean the cage later in her gestation period. Cleaning the cage within 2 - 3 days of her "due date" can unsettle a female hamster sufficiently that she rejects the babies when they are born. Cleaning the cage as soon as possible after determining that she is pregnant may be your best option. After cleaning the cage during the gestation period, do not clean the cage again until 14 days after the birth. Pregnant hamsters need a diet high in protein and fat. Aim for a hamster food that contains 18 to 20 percent protein and seven to nine percent fat. You may also want to provide your mother hamster with milky food to provide additional calcium and promote lactation. Offer your pregnant hamster nutritious treats like carrots, nuts, hard boiled eggs, cheese and greens. You should also put extra food in her cage, as she will begin stockpiling the food for her babies (and will be eating more than normal herself). However, take care with foods that will go bad, since if she stocks piles them the food may go mouldy in her store. It is best to give plenty of dry food, and offer perishable items as treats, in order to increase the chances of her eating it all, rather than storing it. This is important in order to prevent the accidental injury or death of baby hamsters once they are born. Female hamsters may act aggressively toward males when they do not desire a mate. Some hamster enthusiasts claim that Dwarf hamster fathers are actually very helpful in raising the litter. Consult with a vet or pet store hamster specialist if you are considering leaving your hamster dad in the cage. One of your hamster’s first reactions when she gets pregnant will be to build a soft nest to give birth to her babies in. You can help this process along by providing pieces of toilet paper for your hamster to shred up and use in her nest.  Clean facial tissue or toilet paper works best for nest building. It is soft to the touch and very absorbent, and your hamster will be able to tear and arrange it easily. Avoid any long or heavy materials that the baby hamsters may become tangled or smothered in. You only need to do this if you aren't planning on keeping the babies after they are born. If you are having a hard time finding friends who want to take a baby or two, try  posting an ad on Craigslist. You can also check with teachers at local schools, as hamsters make excellent classroom pets. Never breed hamsters unless you want baby hamsters and ready to take care of them. Find them a home or provide for them in your own home. The birthing process usually happens over the course of one to two hours, in about 15-30-minute intervals between pup births. Give her space and do not disturb her during or after the birth.
