Only from her perspective. That sounds like a deliberate "miss", which tells me she's fearful of the live prey. Did you ask when you got her if she was being fed live rodents or dead (f/t or fresh) and if they were rats or mice? It makes ALL the difference to many snakes- & for best results, you should plan to feed any new snake the same thing & the same way as they were previously being fed. It's not only to avoid food refusals, but also so your snake doesn't get injured, when they hesitate or underestimate their live prey. Rats & mice smell different- if she was raised on rat pups (eyes closed) for example, they move but not as much as mouse hoppers, & mouse hoppers have their eyes open & therefore may also fight (bite!) back. So that would explain her hesitation...see?
