eating backwards- any consequences?

my BP was weird today when i fed her, she killed her prey right away, but then pretty much ignored it. I tried covering her, which didn't do any good, then I actually moved her by a light, and she started eating, but ate butt first. Until today, she's been absolutely wonderful with feedings. I couldn't have asked for an easier eater.
Are there any consequences for eating backwards? It looked like she was having a bit of a hard time getting it down, but it did go down. Is she more at risk for regurgitating this way? Just want to make sure everything will be okay. My little corn snake ate butt first last week, and everything was fine, but a fuzzy is almost the same shape front or back, adult mice are shaped differently.

Nope, no worries.
As long as it gets down it should be fine. :]

Every now and then mine will do that..They have a harder time getting it into position (getting both legs and tail inside the mouth) vs head first.. but other than that it should be ok.
