A local television station reports that the cow fell into Kathy Wydareny's covered pool on Monday night. The Anderson resident says the cow belonged to her neighbor.
Wydareny was startled by a "giant whoosh" and took a flashlight out to investigate. She called 911 after spotting the cow.
It took five men from the county rescue team to free the cow using a sling.
Wydareny believes the cow got loose and just kept walking, thinking the pool cover was solid ground.
The cow is doing well. Wydareny hopes her homeowner's insurance will cover the damage to her pool.
