First of all when you get a hamster  it is best to not try to pet it right off, and i'm serious ! even if you pet your hamster in the store just fine. a long ride in a carry cage with strange sounds and smells can really make a hamster scared. even tho i'm positive you really want to touch that fur ball of cuteness. but  you should wait a few days until you try.
 after those few days  when you start to bond with your hamster a good way to start is giving  your hamster treats. those treats can be anything from fresh veggies [without seeds] to the store bought mix.when yu feed your hamster always remember that they  have bad eyesight so if they happen to nip you when  you feed them it is probably  a misunderstanding  so be a little cautious and when you want your hamster to  step on your hand don't leave your thumb  out looking like food. keep your thumb close to the rest of your hand.
                                          until next time! ,
