Greer Ann Gordon was outside playing when she heard the meows.The 7-year-old walked to the right and to the left and looked all over, but the sound didn’t seem to get any closer.Then she looked up — way up.About 55 feet in the air, she saw her 2-year-old cat, Covy, perched in the hardwood at the front of the family’s Forsyth County lake house.It took 18 hours -- and plenty of trial and error -- before the black cat was rescued from the tree, mother Gail Gordon said.“When we first saw him up there, it seemed like he was on top of a mountain,” Gail Gordon said. “He just cried and cried and cried. It was horrible.”They didn’t know how Covy, who’s an indoor cat, had gotten out, much less that high up the tree.
