You haven't done anything wrong!

Your hamster is probably still adjusting to the new cage, food, scents, noises, etc.

They probably weren't expecting to be picked up and became extremely stress when you did so.

This is normal hamster behavior within the first week because the hamster probably isn't aren't used to human interaction in general, especially not yours!

He/she will forgive you, I promise.
