Yes, she will be fine if she needs to wait. Unlike a dog or cat, she won't starve in that amount of time. Although she might be especially enthusiastic about her next feeding time.

It does seem odd to me at two years she has only just now begun to eat two mice in one feeding. Was she a rescue perhaps? Or are you yet another victim of bad pet shop misinformation? Have you considered trying to feed her rats? If so, is there a reason why you couldn't ? Lack of supply maybe? I'd be very interested to find out more about her. Do you think you could share her weight and length with us? Maybe a picture or two?

I dislike passing judgement on cases like this, since if you are worried about missing her feeding for a week, it's obvious you care about her and are doing what you think is right by her. Perhaps with a little help, we can find a way to benefit you both when it comes to her feeding.
