I have purchased this item a total of 7 times. Until this last order, I have had no issues. This last order was different.  When I opened the bag, there was a strong almost ammonia smell. My 2 cats won't eat it. They have never turned their noses up to this flavor before. It hasn't expired. The expiration date is Jan 2019. I don't know what is wrong with it, but I can't use this and I'm going to have to find something else my cats will eat instead.
