Is anyone aware of a change in the formula for the Nupro ferret supplement? The latest canister I bought seems to be a darker brown color and has a different smell. It doesn't smell rancid or anything like that, but it is different from the last one. If there are slight variations between batches, that's fine. I was just concerned that perhaps this canister has gone bad or would otherwise harm my little guys. They seem to like it as much as the other canister, and they don't seem to have suffered any ill effects, but I thought it is always better to be safe when it comes to what I feed my ferrets. Thanks, in advance, as always, Gail, Frito, Bandit and Taz [Posted in FML issue 3436]
