poop or regurge?

[Missie]

this is the 1st time i've fed my corn an adult mouse so i was a little worried she might regurge, but im really not quite sure if this is a poop or a regurge. usually her poops arent as white, and this looks like guts and then a bunch of white stuff? i figured you guys might be able to tell me at first glance. sorry the pic is a bit blurry from the glass, but you can see the mess in the corner there.

Mouse fur isn't digested, so you should see fur in the shat. Usually there is white stuff too---urates I'd assume. Seems like they come out at the same time.

also a regure smells teribble, i think it smells alot like propane.
