Hello ;-) Our Muffin was recently diagnosed with a severe case of IBD on biopsy.(Dr Williams) Her poop was birdseed like, however our other 8 ferrets have had regular diarrhea daily,as well. We just figured that because their gravy is somewhat watery that was normal They are all very robust ferrets. I had been feeding them my version of Churches chicken gravy (entire chicken,bones & broth simmered for 4 hrs & pureed) mixed with Gerbers chicken every morning for breakfast plus chicken based premium ferret kibbles available all the time.Needing to switch Muffy to another food source we chose turkey as the first type.We will be introducing duck and others very slowly. ProPlan makes a turkey & Barley kibble,crappy food (imho) but the only one we could find and we are supplementing it.We decided to also change our gravy & Gerbers to turkey..I bought turkey hind quarters & breast. Hard to change the diet of one semi/free roam ferret & not the others.So everyone "went turkey" To our shere amazement,within one day,all poops were normal.Beautiful lil poopies,btw!! he diarrhea had been going on for almost a year...now two weeks into this we probably have the prettiest poopies in town;) I truly think someone should explore this link of possible chicken "allergies" and develop a few premium "turkey based" ferret kibbles. We had not expected this so I tried chicken the next week just to see,sure enough,yucky yucky diarrhea! I'd love Dr Tom Willard or any ferret food manufacturer to address why they always use chicken.I have heard Innova makes a turkey based kibble as well, but i have yet to find it.ProPlan is a poor excuse (imho) for food but my ferrets are all looking great and their poopies prove something!! I'm hoping the turkey gravy with things like Taurene, Nupro, ProBois & Pet Tinic will improve what is missing in the kibble.I know it is very hard to balance everything. If your ferret has frequent diarrhea,try switching.I think you will be pleasantly surprised!! Just the fact that our 9 ferrets improved drastically, showed us something!
