Florida woman Kris Hedstrom demanded DNA from the father of five goats she bought from her neighbour Heather Dayner for $900 (around €800) in December.

She wants to establish the lineage of the five Nigerian dwarf goats in order to register them with the American Dairy Goat Association.

But Ms Dayner – who has described the claimant as “a nightmare of a neighbour” – claims she offered a refund instead, the Tampa Bay Times reports.

The lawsuit filed by Ms Hedstrom demands either a refund on the goats or DNA to prove their lineage.
