She just defecated in her cage on the new substrate from the looks of it. Another hydroball like I thought I felt the other night in the lower left corner of her side. So... she swallowed two hydroballs and a cricket at the same time which contributed to her choking on them and being able to swallow them both. I guess I got lucky, and I hope I never see that again. NOT worth it, even in a substrate that she clearly liked a ton in comparison to this coconut fiber.
