<< One of the characteristics used to decide whether to keep a pig for

I assumed that all pigs would have the same number of teats!  By how much
would the number vary?  Is this true for other animals as well?  Were the
extra teats like ancillary nipples on human moms, an unusual occurance, or
are they a regular variance?
