Nature's Variety No Grain Sterilised Free-Range Chicken

I've been buying this cat food for many years, sometimes from Zooplus, and never had any problems. But I'm really disappointed with my last order: a lot of the kibble is very broken, so my cats won't eat it; and the worst part is that the smell is nauseating, like blue cheese. I thought maybe they'd changed the recipe, but AI tells me it could be due to excess moisture. I'm not sure if I'll buy it again.
