Mad Whatsis Disease

There is a lot of noise going on about another possible case of Mad Cow Disease, also called Bovine Spongiform Encephalopathy or Creutzfeldt-Jakob disease in the U.S.. Don't you love these names?

Anyway, the interesting thing is that all the reports talk about "the animal". Well what kind of "animal" was it? Are they withholding the species pending notification of next of kin? Are they afraid there will be some sort of a run on ________ (fill in the blank; A: Goats, B: Sheep, C: Squirrels, D: Possum, E: None of the above)? After all, it couldn't possibly be a cow!
