That sounds like it might be that very intermittently shed and small coccidia species, Troy. I am so sorry that you and others have gone through this no matter what the cause is. The place that can help find the cause from specimens or cadavers: http://www.ferrethealth.msu.edu/ which is much, much, much better than the standard labs. MANY THANKS to those who remembered us while a human family member was so very ill (especially my fellow FHL moderators and Bill and Helen) and during his two emergencies recently, and to all the FHL moderators who did the vast majority of my work, too, during that. He is home and halfway comfy and will be having a smallish surgery as a follow-up which will result in the problem being completely corrected. When the surgery will be done will depend on future test results so may be as early as next week but could be in two or three weeks or maybe even later. Many thanks, too, to Patty for a great deal of guidance and patience, more than she knows. Meanwhile, loads of meds, and other special things to continue to do but he is up and walking around and beaming about being able to... The FHL moderators are Pam Sessoms Patty Kaczorowski Troy Lynn Eckart Dr. Bruce Williams Julie Fossa and me.
