The Nips Are Getting Bigger

(To quote Mental As Anything). Or at least, the nips are to be getting more plentiful, as NZ tries to breed four-nippled sheep. SMH quotes a Otago Daily Times report that:

'New Zealand scientists are trying to breed sheep with four nipples instead of two to cater to a growing tendency of ewes to have multiple births.More ewes are having triplets, but one of the lambs usually struggles to survive because it cannot get enough milk from its mother.'
