If your pet sleeps for about 10 to 20 minutes during the daytime and is active but not much like to play with toys, your pet is mature. Your rodents may want to be alone and love to eat food according to mood. 

When you observe all these habits and behavior of your pet, then it is confirmed that it is about 4 to 6 months old.

Physical appearance can help to estimate the age of your hamster

Its physical appearance changes with the increase in age. If the size, eyes, ears, feet, and hands are tiny, it means it is a baby, and its age is about 14 to 17 days.
