So my cats were just not eating the Friskies I got from Costco, even though they eat friskies regularly. Some flavors they don't love, but they normally adjust after a day or two. They were not adjusting this time -- its been almost a week. They would eat one can a day slowly under protest and dry at night as opposed to 2+ cans. Finally, I checked the box -- "January 19". Shit, I'm a bad cat dad. Well, I think it just didn't smell/taste good, I don't think it made them sick. Ticked at Costco. That isn't a little expired!
