Erika, did your ferret sitter give the fuzheads water from the tap? One problem that has occured with our fuzzies is change in water. Also, water in different areas has different things in it. The water they received may have had a bug that is affecting their digestive tract. Best to bring water with you to sitters. May want to see your vet. They may need to give the fuzzies some saline under their skin to help with dehydration due to the runny stools. Kim, have you seen your vet yet? We had a problem like this when we were new fuzrents. Max, a beautiful male sable, had something that sounds similar to your problem. Turned out that it was cancer. It started really small and almost unnoticable and stayed that way for some time. When it did start to grow, it was too late to save his leg it engulfed his bone before the appointment we made to have it removed. I highly reccomend that you get your fert to the vet ASAP. With a biopsy they will be able to tell what it is. Hope it isn't anything serious. Brenda [Posted in FML issue 2316]
