If you have an optical mouse, Alffe, the one with a little light on the bottom? Check for lint accumulations there in the little hole.
Little fine lint strands can reflect the light and may your mouse jitter around. I get this sometimes and use a tweezers to remove them. I have a cat pad with fake/faux fur next to my monitor for the cats to rest upon, and sometimes tiny link from that ends up in my mouse light window that is under the mouse.
