Liedra,
There are many reasons why your snake may of regurgitated, but the most common is handling soon after feeding, as Greebo mentioned, one other common one is that the food is too large and once eaten has rested uncomfortably in the snake, and so it feels it needs to get rid of it, and regurgs it.
Was the food item larger than you normally feed?
Sometimes when the temps are too high snakes will regurgitate!
Other reasons for regurge can be internal parasites, worms , protozoa etc.., but very unlikely if your snake is a CB 8 month old animal.
Have you introduced any new snakes into your collection recently?
I guess is the same as Greebo's the handling, but if not, the food has probably been resting uncomfortably.
Leave it a week before you try to re-feed.
If you find she does the same after her next feed and you have considered all the above then, go see a Vet and get her checked out, a good Vet that knows about Reptiles! If there is such a thing!
Hope all turns out well, I think that it will, so don't worry too much, I don't know anyone who hasn't had a regurge at some point in there time in keeping snakes!
Regards,
NCHERPS
