One little piglet didn't come home.

A pig was stolen sometime Thursday from Penn State's Animal Evaluation Center. A hiker found the male pig Friday morning, Penn State Police Services said.

The pig was taken from a pen in the evaluation center and appeared to have spent the night in the cold. Penn State police said the man found the abandoned animal in a recycling bin after hearing the animal's shallow breathing. The pig was unresponsive and suffering from exposure and an inappropriate diet.

Penn State police believe that this may have been a prank and that the suspect or suspects might have fed the animal something to make it ill. A Penn State veterinarian is caring for the pig and said it is in stable condition.

The College of Agriculture and University Police ask anyone with information to call Penn State Police Services at 863-1111.
