She’s down to eight lives.

An Upper West Side tabby proved that cats always land on their feet after she fell 12 stories from her owner’s West End Avenue apartment and survived slamming into the roof of a neighboring parking garage.

Angela Lang, 32, a lawyer who moved to the city this month, said little 9-year-old Copper wound up with only a broken paw after her fall, leaving veterinarians amazed.

“It’s just remarkable,” she said. “They said they didn’t think she would make it.

“They actually suggested we put her down. But I said, ‘Let’s give it 24 hours.’ The vet called her a miracle cat.”

The trouble for Copper started shortly before 11 p.m. Monday, when Lang was getting ready to give her and another cat, Daisy, their nightly treat.

“Daisy came for a snack and Copper didn’t,” Lang said. “That’s when I realized that she was missing. It took me about two hours to find out that she fell.”

Copper had apparently gotten through Lang’s 14th-floor window, which was open only about 3 inches wide and held in place by a window lock.

“I didn’t think she could fit through the window,” said Lang, who had never lived in a high-rise apartment before. “She’s never done anything like this, but she is the explorer of the two cats.”

After the fall, the injured Copper spent nearly nine hours on the roof of the two-story garage because there was no access and Lang couldn’t get hold of anyone who could help.

Finally, the next morning, building service manager Juan Dominguez, 42, was able to help. He said he spotted the cat on the roof from the window of his own apartment, which is 10 floors below Lang’s.

“She [Copper] was scared, cowering next to the wall,” he said. “Then we started to move fast to help her.”

Dominguez climbed down a ladder from his window to the garage roof and carried Copper up in a laundry basket.

“It’s a miracle,” he said. “I would have never thought the cat would survive that.”

Copper is now home recovering and sporting a cast on her back right paw and a medicinal patch on the back left.

She also has a scar on her face and a patch of fur missing from a paw where she had an IV. She is otherwise no worse for wear after her incredible plummet.

“The vet didn’t think that she would be able to survive but she did,” Lang said. “She’s a real fighter.”
