The firemen were called to the apartment in Rio de Janeiro on Tuesday after the pet got stuck on an air conditioning unit, local TV network Rede TV s.
Footage shows one of its rescuers climb out of the window above the cat and attempt to abseil down to it.
But the terrified cat gets spooked and tries to flee scrambling up a flyscreen before losing its footing.
Onlookers scream as the cat hangs with one paw onto another air conditioning unit on the floor below before losing its grip.
After several failed attempts to grab the cat, in which the feline appears to use all of its nine lives, it plunges to the ground where other firefighters break its fall with an outstretched blanket.
The cat escaped the fall uninjured and was taken to a local animal welfare shelter until it could be picked up by its owners.source
