Hamsters licking human hands may be due to the following four reasons:

1. Showing favor to the owner: Hamsters licking the owner's hand is a sign of liking and accepting the owner.

2. Hungry: When a hamster is hungry, it will ask for food from its owner by licking its owner's hand.

3. Lack of nutrition: Human skin secretes nutrients such as trace elements, and hamsters obtain these nutrients by licking human hands.

4. Recognition: Hamsters will also lick their owners’ hands to become familiar with their owner’s taste, which is also a sign that hamsters are recognizing their owners.

Tip:

Be sure to wash your hands promptly after a hamster licks your hands. If you are accidentally bitten by a hamster and bleed, there is a chance of infection.
