The owners of Tilly the Shetland pony received a double shock when she
gave birth. They didn't know she was pregnant - and they certainly
weren't expecting a zebra.
Tilly's
owners at Eden Ostrich World, a modest visitor attraction on a farm near
Penrith in northwestern England, had been unaware of the pony's exotic
past life at a wildlife park, where she shared a field with a male
zebra.
"She was fairly fat when we received her and we thought that she
was getting fatter," Ostrich World manager Karen Peet said.
"It really was a bit of a shock when we got up one morning and
we saw the foal that was there."
The striped half-Shetland, half-zebra foal - dubbed a "zetland"
or a "shebra" but as yet unnamed - has flourished since her
birth a week ago, and Peet said visitors would be able to view her
beginning Monday.
The farm plans to hold a competition to name the creature, which has
black-and-tan stripes and a zebra's distinctive large head.
Veterinarians say such a foal is rare, but not unknown. British zoos
have reported the birth of several "zeedonks" - offspring of a
zebra and a donkey - over the years.
"Ponies and zebras very rarely share the same environment even
in the wild. A meeting between the two is very rare in the natural
environment," said Lesley Barwise-Munro, spokeswoman for the
British Equine Veterinary Association.
"If the zebra is the father and the horse is the mother there is
no reason why a normal fertilization and a pregnancy should not take
place," she added. "But the offspring is unlikely to be
fertile."
