Monkey see, monkey do

It's official: the British are morons. So say the RSPCA, for whom an advert showing a guinea pig drinking tomato ketchup is going too far. A spokeswoman for the RSPCA said: "Water is an essential part of a guinea pig's diet and we wouldn't recommend replacing it with ketchup. A small amount of ketchup as a treat now and again shouldn't do any harm as long as there is plenty of water available." I'm glad that's been straightened out: presumably the same condescending advice applies to the keeping of tropical fish.
