Wealthy residents of some of Australia's poshest suburbs are paying $78 an hour for professional pet walkers to take their cats for a stroll.

Pet sitter Sarah Kwong charges $38 per half-hour visit and makes a tidy sum from 'fur parents' in Sydney's eastern suburbs and north shore. 

Such financially frisky felines are often feted as full members of the household on par with human children, which pet sitters say is a concerning trend.

Cat walking is not a walk in the park even for professionals as there has been fierce backlash from dog owners worried the felines will be savaged by their nemesis pets.
