Not all Carpets are nippy, but they do have a reputation to be more on the defensive than others. I have always started to handle after a meal and a few days to start settling in, and she already lets me take her out without striking and calms right down once she is out. They are one you need the patience to work with and to continue working with. I can tell already she is settling in nicely and will tame out very, very well and be a great ambassador for her species...
But you gotta love the effort of those love taps! She is an absolute sweetheart and she will always have a great forever home...
