so my hog island's been soaking a lot, so i changed her hides under the assumption maybe she didn't like the ones she had and never used. so i bought new ones and she uses them and soaks less. still soaks, but not as much. today, i come home and there's brown flecks in her cage, nothing i could see on her, but brown flecks in her cage and water. mites? what do i do?
