She moved from Poland to America when she was three, in 1982. She went to a school for speaking English at 7 years old. She is now speaking English from that day. Catherine speaks English and Polish.
She was seen in the first video wearing a purple camp shirt in "Boom Boom Ain't It Great to Be Crazy" where she watched and cheered for the kids in the race alongside Dannon, Myisha, and Josh. Catherine was also mentioned picking up a bunny in "Little Bunny Foo Foo". She even worked together with Myisha on building the stage in "Whistle While You Work".
In the second video, Catherine wore a white shirt. She was best mentioned in "Whole Lotta Shakin' Goin' On" where she sat with Hillary as they rode the roller coaster. Catherine was then mentioned in "Little Deuce Coupe", "A Pirate's Life" (where she dressed up as a pirate), and "We're Gonna Get Wet" (where she rode on the water rides).
When she is not in Kidsongs, she likes to play classical music on piano and listen to music by Chopin.
Catherine left and was possibly replaced by Jenna Dickman for the latter video.
