Some ferret treats are not good for them at all. If they contain any dried fruit, it can clog a ferret real quick. Some ferret treats have lots of banana chips in them. Just because it says it's for ferrets, doesn't mean it's good for them. Hartz Mountain feeds are often dangerous to a number of animals (lack nutrition). I've heard of birds starving to death while "eating" their bird seed (because so many of the seeds were empty). Don't let the fact that it has "ferret" in the name fool you.
