It took six firefighters, two council rangers, and one very large cherry picker to rescue a kitten trapped on a building awning 50 metres above a busy Burwood street.

The Fire and Rescue crew were called to the corner of Elsie and George Street after the cat had fallen from a sixth-floor balcony of a residential tower around lunchtime on Wednesday.

A crowd of up to 100 people had gathered below, all craning their necks as they stared up at the kitty perched precariously on the grated awning.

The firies from Burwood station realised their ladders were too short to reach the cat, and called in the crew at Parramatta who soon arrived with a cherry picker, a "bronto​" so large that they had to close down the street.
