Meat Witholding

I'm doing this thing where you restrain a cat three times a day to put eye ointment in. Been doing that for over a week, so it's now routine.

Today I read the tube, and in bold it says "MEAT WITHOLDING PERIOD 28 DAYS". Which is really bad - because the cat's been eating plenty of meat. I re-read it as I'm trying to work out how bad it is that I've been feeding the cat normally... then I realise it means no-one should eat the cat for 28 days.
