Well, something caused the impaction, I saw coco fiber coming out, the lump is smaller now but still isn't cleared out. Maybe it was the mealworms, I won't doubt it.
It could have been a few thing, but its hard to tell. Hopefully its just slightly constipated. Full blown impaction is bad and usually is very difficult to pass because its usually caused by something that cannot be digested such as stones, bark, eat.
