hi mike, we have 2 ferts and what we do is wash ALL their bedding at least once a week, make sure that their cage is clean, (i'm not saying that you don't clean their cage ,promise!!) and they get bathed 2 times a month. i tried the odor stuff from marshalls and we didn't notice any difference at all. personally, i think that they just sell that stuff to make money. anyways, one thing that has helped quite a bit is when i bathe my guys, i put a little baby oil or avon's skin so soft in the water after the shampooing, and it helps for a little while with thier smell, it also keeps their skin from getting too dried out. basically, as far as i know, that's all you can do. i have had people say that their surprised that they can't smell them. seeings how " they smell sooooo bad" LOL i think that is too funny. what kind of litter are you using? if i can think of anything else, i'll let you know. and if there is anything that i can help you with, please let me know. there are also some very good fert sites out there. one is [log in to unmask] , the ferret owners manual( i had to go thru ask jeeves to find that one) and alot of others. good luck!!! dooks!!! jamie & the fuzzy crew [Posted in FML issue 4062]
