I'm sorry to hear that. I was really pulling for her. She's one that I thought had a chance to make it. If possible, a necropsy on her might be helpful to determining her cause of death and may help your remaining one if she should fall ill. After she has settled in I'd still recommend doing another fecal exam on her. For best results, try to take a fresh one immediately to the vet to have it checked. Good luck with your remaining one and let me know if you need any help.
