Just had to say I really appreciate what Deborah Kemmerer said about additives. Right on! I've fed Mazuri Ferret Diet for 9 years with absolutely no problems. Supposedly it has that cancer causing exothyiquin. Never had a cancer never lost a litter. Had 1 false pregnancy. So, am very glad to have someone explain in a better way exactly what I have been saying. Good job! Thanks Judy Moon/Moonsong Ferrets [Posted in FML issue 2616]
