Last week my albino bull snake had appeared to have regurged a rat. It was not digested at all. I attemped to feed her again this week, a smaller sized rat, which I did yesterday night. Now today, I found that again, in the same manner. I'm really worried about her, nothing appears wrong. She is acting like she normally does. She's in a rack with my other bulls and they're all perfectly fine as well, nothing has happened like this with them. Did I try to feed her again too soon? Is it because of the changing seasons? Something else? I've never had this happen before. Should I isolate her from the other snakes? Could it be parasites? I have no idea what happened. Any help would be appreciated.
