Yes felons lose the right to vote in California, but only until the end of their punishment. There's a ballot initiative we get to vote on this election that will allow felons to vote as soon as they are released from prison, rather than waiting until the end of any probation or parole. Naturally, the law enforcement PACs think this measure would cause the sky to fall. Only one poll I'm aware of, but it looks likely to pass.
