Mites were just a thought, and come to think of it, if she is burrowing for extended amounts of time, that will most likely not be the case. You can see mites, they are VERY small, but if you look closely, you will see them. I doubt this is the case though, so we could probably rule them out. In cases of an animal having mites, the animal seeks the water to rid or comfort themselves from all those tiny bugs crawling all over them. I do not think this is your issue once again.

Impaction will feel like a hard (semi-hard) or tough lump in the sides of it's stomach. It will slightly protrude a bit farther than one side of the stomach.
