Firefighters rescued five pigs, but only one of them survived.

GRANTS PASS — A barn fire in Grants Pass killed 16 mini micro potbellied pigs. Rebecca Moran told the Grants Pass Daily Courier that the Sunday fire killed both her sows and most of the two pigs' litters.

Moran says she and her husband, Todd, were out of town for the weekend. Their housesitter heard the pigs making a noise and found the barn burning, but was unable to get the pigs out.

Firefighters rescued five pigs, but only one of them survived.

The Morans still have two pigs they took on their trip.

Authorities have yet to determine the cause of the fire, but Todd Moran says he thinks it may be related to heat lamps they rigged to warm the pigs during cool weather.
