Why does my Hamster licks my hand?

  I have a hamster named Doodle ... it is a name which first came to my mind when i first got him ... he is an active one and we had many fun times ... i sometimes let it bite my finger on purpose and he does not really bite ... Doodle only so call nibble it and it does not hurt abit .... but over the last few months, he stopped biting and instead, he started licking it! Why is Doodle doin it? Im just curious ... everytime i greet him by puting my finger in front of him to let him bite, he licks it now adays ...
Sounds like he needs a salt block, although may just be his nature.



Animals have a tendency to lick to get the salt like substance naturally found on your hands.
/Human hands might smell good and taste salty, so thats probably why he's licking you. Sometimes my guinea pig doesn't know if my finger is a carrot or not.
my hamster does that too. esp if my hand is wet or smell food. try even put in next to ur eyes .. if they sense water they start licking.
my hamster licked my face once it was odd
