well i have a hamster and it only produced 2 pups so it's normal.

when you notice your hamster is about to give birth you will have to separate the dad from the mom
Hamsters usually have litters that consist of 4 to 12 pups, although it can vary depending on the breed and the specific hamster. It is important to note that a mother hamster may require support and monitoring to ensure the health and well-being of both the mother and the pups.
Yes, Actually this is very normal and you should see it on your hamster when she is pregnant. They should be very large and a bit squishy. Don't toutch them too much though. These are milk sacks on the hamster as hamsters are mammals, and all mammals drink milk when they are infants. So, Don't be scared that your hamster has 2 large lumps on her hips. It's only milk sacks on her :D
A normal hamster's lifespan is about 2-3 years.

Normally they have 3-4 pups in a litter but it has been known to only have 1-2, it will depend on the size of the parents as well
