​Masock says the cause of death isn't known.

Cavanaugh lent her voice to many of the 1990s indelible cartoon characters, including Chuckie Finster in Nickelodeon's Rugrats, Dexter on the Cartoon Network's Dexter's Laboratory and the live-action piglet of 1995's Babe.

Cavanaugh retired from voice acting in 2001 and moved back to her native Utah.

In the LA Times notice, her family wrote that "in each role there was a part of her showing through that the ones who truly knew her could see."
