Photo taken in Korea 1953. The kitten, Miss Hap was only 2 wks old. The kitten was rescued by Marine Sergeant Frank Praytor. In 2010, Praytor wrote, "Miss Hap was weaned on meat out of C rations and grew into a big girl who thought I was her father. When I left Korea, I left her in the care of another Marine. When I returned in '55, she was alive and well. At 83, I'm still saving orphans. Have two cats, Molly and Max. They never leave the house."
