Funny you should bring this up!! I've been feeding my fuzzy's the 8and 1 Ultimate and Natural Gold. They started on Marshall's, (yuck) but I do have to admit, when they were on the marshall's they did VERY WELL. No oder either. But since I have them on the Natural Gold, whew!!!! Their poo really stinks!!! ALMOST to the point of going back to Marshall's and staying with the 8 and 1 Ultimate. I did also use the Bi-oder, but lately have not had the money, but I do now and will be running to the store to get more!!! Please no flamers for my food choices, I go with what makes my fuzzy's happy and healthy and I don't pick on anyone else for what they choose! I know Marshall's is not the best food out there, but I did see a BIG difference in my guys and they did thrive on it, maybe because they are Marshall's ferrets, who knows??!! But I do like the 8 and 1 Ultimate and the Natural Gold. I'll see what happens once I get them back on the bi-oder, but if it takes Marshall's food to even things out, then I'll add that to the other 2 foods as well. After spending hours in the store reading all the ingrediants on all the ferret foods that are out there? They must have thought I was nuts!!! Marshall's is far from the worst food out there!!! Some of the things I found in some foods had to me yelling and talking outloud to myself!! I thought for sure the store was going to send in the men with the whitecoat at any second!!! But for now, I'll be getting the bi-oder and see what happens and take it from there, I'll do whatever it takes to make my babies happy!!! and my nose too!! LOL!!!! Not that I care what smells are going around, but I'm not the only one who has to live here so I have to be considerate at least for them!! Darlene & Addie & Booboo [Posted in FML 6419]
