How old does a baby hamster have to be when you can pick it up?

It is generally recommended to wait until a baby hamster is at least two to three weeks old before handling it. Before this age, they are very fragile and easily stressed, and their mother may become aggressive if she feels her babies are threatened. At two to three weeks old, baby hamsters are usually strong enough to be handled gently for short periods of time. However, it is important to handle them carefully and support their bodies fully to avoid injury. You should also wash your hands thoroughly before and after handling a baby hamster, as their immune systems are still developing and they are susceptible to illness.
