jQuery animate border color on hover?

Using a color plugin to animate background color on hover.

$(function() {
    $('.listing-2 li a').mouseover(function() {
        $(this).animate({
            backgroundColor: "#0e7796"
        }, 'fast');
    });
    $('.listing-2 li a').mouseout(function() {
        $(this).animate({
            backgroundColor: "#d6f2c5"
        }, 'fast');
    });
});

How can I do the same for border color?
