Nope, i have mine around my neck pretty much all the time, last summer when it was warm enough to have my girl outside during the day i would just put her around my neck and go out for the day. Nyxx love to be around my neck and i trust her to the point of letting my mother do it as well. She have never even " Looked" like she was about to bite or scared to the point of coiling back. I think i got lucky because ther isn't anything that makes her scared. Even a dog jumpin on my lap while she is on my wrist or neck does not even make her flinch heh.
