Hamsters generally reach adulthood 2 to 3 months after birth.
The growth stages of hamsters can be divided into the following periods:
Juvenile Period: From birth to 3 months old, baby hamsters during this period are very cute, which is equivalent to a human being at the age of 20.
Adult Period: From 3 months to 1 and a half years old, during this period, the hamsters' bodies have fully developed and they are full of energy.
Old Age Period: After 1 and a half years old, the hamsters' bodies start to show signs of aging and they require more care.
You can determine the age of a hamster by observing its appearance characteristics and behavioral changes. For example, juvenile hamsters are small in size and have soft and shiny fur; adult hamsters are larger in size and have coarser fur; the body size of old hamsters doesn't change much, but their fur will become dull and may even experience hair loss. In addition, the puberty of hamsters usually occurs when they are 5 to 8 months old. At this time, they are capable of reproduction, but it is best to wait until they are fully mature before breeding them.
