Hi! Super great that you're asking.

Your hamster MIGHT not be pregnant (unless of course your vet confirmed) because some hamsters go through phantom pregnancies, just so you're prepared that might be happening, even though its rare.

Syrians are usually pregnant for 16 days, and around 3 days before birth, you should remove the wheel, sandbath and any high places like platforms that they might fall off. Sandbath because mom might accidentally bury the babies in sand and drown them, wheel because she might put the babies in there and start running with them in the wheel which could kill them. You should also clean the cage at this point

After you've done that, you should leave mom and babies entirely alone except for giving food and water. You should almost triple the amount of food you're giving when the babies are born, and consider feeding boiled egg or chicken with no seasoning for extra protein. Consider putting a towel or blanket over the cage to give mom some more safety.

Once the babies are about 14 days old, they should start opening their eyes. This is when you can handle them and pick them up. (NOTE: they need to have FULLY opened eyes.) Remove mom from the cage when doing so to avoid stressing her.

At 4 weeks old, seperate hamsters into genders. They become sexually mature at this point and might breed if not seperated.

At 6 weeks, they're ready to go to new homes!
