Station Officer Chris Macdonald said it took the crew about 30 minutes descending into manholes before successfully rescuing the kitten.
"With the torrent of rain [on Sunday], it would have drowned had it not been heard by a member of the public and rescued by the fire crew," Macdonald said.
"The kitten, given the name Blaze by the fire crew, was then cared for overnight by one of the brigade members' daughter and has since found its forever home."
