Blood on Bedding?

[Alexandra V]

Eww, I didn't know feeder bellies exploded, haha. She has no open wounds, and she shed over a week ago. Maybe since I have to feed her two 'fresh killed' mice one exploded? (2 mice cuz she wont eat a rat)

It sounds to me like it's blood from the feeder. If she has no bodily signs of injury and it's not in the stool, then it sounds like that's the only logical explanation. Good call on the vet visit, and a 9-snake bill sounds like no fun at all!
