Maybe cat is ungraded, and there is some cross-importation treaty with Korea or wherever it came from that proof of Korean inspection is enough to get USDA okay and vice versa. Funny that this is OK with them as long as it’s imported cat. Domestic cat, that’s a whole nother ball of yarn.
As for "...is OK with them as long as it’s imported cat. Domestic cat, that’s a whole nother ball of yarn." I'm not so sure. From the story, it sounds like the law regarding eating 'domestic' animals is a local or state statute, I've never heard of a federal regulation like that.
Aw hell, who knows? Maybe there are standards for cat. There are for other exotic meats. Look at ostrich, rattlesnake, alligator, etc.
Just one of those things that make you say: "Hmmmm..."
