Diet helps roly-poly hedgehogs

Overweight hedgehog

Fourteen hedgehogs that became too fat to protect themselves have been returned to the wild.

The animals were put on a strict diet in February after pigging out on too much cat food at a Wildlife Rescue Centre in Fife, in Scotland.

The hedgehogs had got so fat they weren't able to roll themselves into a ball, which meant they wouldn't have been able to hide from predators.

Now they're fit and healthy and ready to fend for themselves again.

A total of 70 hedgehogs were rescued during the winter and taken in to the Wildlife Rescue Centre in an effort to protect them from the harsh weather conditions.
