Ok, so you’re saying that “foot” is an ok substitute for hooves????
“Was” rather than “is” - common usage on this point has moved on in Britain in the last 100 years: but, as I explained in that earlier post quoted by DeaconBenjamin, the older usage has survived in the name of the disease, which is never called “hoof and mouth” here. Incidentally, just heard that this second suspected case has now been confirmed.
