The duo, dressed by the Zuma Originals and DappaBox.com respectively, will be working alongside the Cat Haven, which will let people play with kittens for a gold coin donation on Saturday, April 23.
Mr Mewburn said the Subiaco Street Party would give them an opportunity to tell people about the Cat Cafe.
“For us, the festival is for those who don’t know much about us… for people of Subiaco who are curious about what we’re doing,” he said.
“We want people to be aware of our social intentions.”
Mr Mewburn said the Cat Haven, the Perth Cat Hospital and an animal behaviourist were involved in the venture to ensure the wellbeing of cats and customers.
A performance by eight-piece band The Catz Meow on the main stage and free cat mask-making workshops will add to the cat theme at the inaugural festival hosted by The Subiaco Network and See Subiaco, and sponsored by the Western Suburbs Weekly.
From 2-9pm, Rokeby Road between Hay Street and Barker Road will be alive with free entertainment including live music, street dancing, roving performers, laneway jazz, giant characters, street food stalls, pop up laneway bars, street vendors, vintage market stalls, children’s fun zones, a side show alley, carnival rides, arts and crafts workshops and live comedy.
