Kava made her television debut on the 1976 CBS series Ivan the Terrible, as did Star Trek: Deep Space Nine actress Nana Visitor.

She also had recurring roles on Dawson's Creek and The Practice. On the latter series, she worked with the likes of Robert Curtis Brown, Bill Cobbs, Gregory Itzin, Richard McGonagle, Leon Russom, and George D. Wallace.
Her earliest feature film credits are the Michael Cimino films Heaven's Gate (co-starring Brad Dourif and Terry O'Quinn) and Year of the Dragon (with Jack Kehler). She played the mother of Tom Cruise's character in Oliver Stone's acclaimed 1989 Vietnam War drama Born on the Fourth of July, which also featured Reg E. Cathey, Bob Gunton, Ed Lauter, Mark Moses, Richard Poe, and Mike Starr. Her other films include Little Nikita (1988, with Richard Lynch) and Snow Falling on Cedars (1999, with James Cromwell and Cary-Hiroyuki Tagawa). Her made-for-TV movies include 1989's Cross of Fire (with Dakin Matthews, Richard Riehle, Stephen Root, William Schallert, and Keith Szarabajka), 1990's Murder in Black and White (with Tom Wright) and Murder Times Seven (with Andreas Katsulas), 1991's Guilty Until Proven Innocent (co-starring Mark Metcalf) and In a Child's Name (co-starring Jeff Allin, James Cromwell, Louise Fletcher and David Huddleston), and 1996's Shattered Mind (with Brett Cullen and Richard Herd).
