Sorry, Atom. Yes, I was joking.
I assume (but don't know for sure) that the regulations against importing pet food with bovine ingredients is not so much that your fish might get Mad Cow Disease, but that your fish (or cat or hen) might end up being part of the food chain after eating the uncertified food.
Personally, I think we should just stop feeding meat to cattle, which are meant to be vegetarians.
lol, I'm not sure if you are joking or not. I assume you are...??? Too early for me to tell ;p
When I read bovine ingredients I just assume it's got beef heart or something in there.
