The Norco Animal Rescue Team along with the Norco Fire Department, Norco Animal Control and a veterinarian were called in to help.
The veterinarian anesthetized the horses in order to facilitate their rescue. Once they were properly sedated, the horses were placed on what Berwin Hanna of the Norco Animal Rescue Team called "Teflon sleds."
The sleds made it easier to pull the horses up the slope without getting caught on anything. The so-called Teflon sleds were connected to a large animal lift, which pulled on the horses in an even fashion.
The rescue operation began around 11 p.m. Sunday and ended around 3 a.m. Monday morning.
The horses woke up later with no injuries.
