To Troy Lynn: >Now for Marley. I hope our experience will help others. The vets don't >know why Marley got better but I think I do. Last night when we got home >Marley had another dark forest green unformed stool so I dissected it and >found quite a bit of tangled pieces of fur. Bravo for you!!!! I like it when owners take it on themselves to dissect stools. Too many owners won't do it, and foreign bodies get missed far too often. I think you are on the right track. Many ferrets are getting their winter coats right now, and now is the time of year when we see a lot of hairballs. Hairballs don't often show up on radiographs - sometimes with barium shots you can see something that looks a bit like hair but only occasionally. I would suggest some Laxatone for a week or so, because there is probably more fur in there working it's way through.....
