Meet Lisa the Geep - yes, a cross between a goat and a sheep!

She was born after an unscheduled amorous encounter on the farm of Klaus Exsternbrink, in Schwerte, in northern Germany's Ruhr Valley. One of his young billy goats leapt over a fence and had a passionate liaison with a ewe.

The result a month ago was Lisa - resembling a lamb in shape and stature, but with the colouring and agile back legs of a goat.

Her mother seems unfazed by her unusual offspring and has raised her happily so far.

Now Lisa is booked into a specialist animal medical school in Hanover for genetic tests to determine her hybrid status. "These whims of nature are extremely rare," said the school's Professor Karl-Heinz Waldmann.

"But goats are known for their strong sex drive."
