How to care for newborn hamsters
Assess the parents' risk factors.
Hamsters reach sexual maturity as young as 6 weeks old, though it is not advisable to let them mate at this age. A female should be at least 8-10 weeks old before mating, and males 10-12 weeks old.
Once a hamster reaches 12 months of age, it should no longer be bred, as health risks skyrocket. The average hamster lifespan is 18-24 months.
