Hi, I have about 50 ferrets, most of them are staying inside, a part in the "shed". You cannot smell them at all although nearly none of the ferrets been helped, they are all whole.. So I wonder where the smell does come from..if your 3 ferrets are smelling that terrible you probably should cleen the litter pans more often. I clean them every day, also while mostly about 8 ferrets are sharing one pan together. I clean all the cages every day. Perhaps you should change the food..some food (like James Wellbeloved) makes your ferret smell terrible also fish does (don't know if you feed that). The ferrets from hunters mostly do stink because they eat rabbits and things like that.. So if you have a clean room, you clean the litter pans every day and the cage it normally speaking isn't possible your ferrets smell that terrible you would need a HEPA filter or so. Wish you luck with the "smells" etc. Carmen ===== F.F.F. NL - Pb 12, 4024 ZG, Eck en Wiel Tel/Fax. 0344-692790 GSM: 0651-371058 na 19 uur 0626-482829 [Posted in FML issue 2862]
