It seems as though they're trying to protect themselves from you. Perhaps they were neglected and didn't get very much human contact so therefore they are not used to being handled. (which is quite sad) As sad as it may be they could have been abused and don't trust humans. Do you know why one of the rats tails is half gone?



If they continue to nip/bite at you, you may need to purchase some gloves and pick them up that way until they get used to you and trust in you. Once they trust you (and you WILL know when a rat trusts you) then you wont need the gloves anymore. Just make sure that you give them lots of love and attention and they will want to give you their love and attention right back.
most small animals are easy prey, if you pick them up from above it feels like a hawk picking them up from above.Thier natural instant is to bite back.give them time, care, and patience and remember to play with them everday if possible. With time and patience, they Will come around. HAVE FUN
its because they're scared. They've just been moved, they have no idea what's going on ... and now this giant is reaching towards them and they're freaking out. Give them some time to get used to their surroundings and get comfortable with the move. Then show them your whole hand, not just a finger (it looks like food to them).
give them time to adjust to their new home pets question and answers,www.5d2d.com

give them a week before you start trying to handle them your house smells different
your friend prolly never pet them etc so they got wild and he might of abused them
They hate you!
Your fingers are made of sausage.
