Sybil Featherstone was the owner of a missing budgie who put a notice regarding her pet in the window of the Kabin in 1990. The grim-faced woman dealt with Mavis Wilton, explaining to her that Boris had flown away when her son Wayne let him out of his cage with the window open. A few days later, with no sign of Boris, Sybil paid a second visit to the Kabin to complain to Rita Fairclough that the notice wasn't visible enough. Rita agreed to reposition it to a place more to her liking.
