Can I get rid of the Mickey Mouse glove?
Mousecape may be the answer for you. It has not been updated since last July (though notes from February 2014 claim compatibility with Yosemite...not sure how that's possible) so YMMV, but it may be worth a shot.

On the page linked above, make sure you click on 0.0.5 and NOT "cursor flip". Clicking on cursor flip will download a related program that is not what you want.
