CSS3 add cursor transitions

Is it possible to add a css3 transition to a cursor image which in the body tag without animate the whole body ...

perhaps adding the class somewhere?

.cursor { cursor: url("/images/light1_CROP.png"), auto;
  animation-iteration-count: infinite;
  animation-name: changewidth;
  animation-direction: alteate;
  animation-duration: 4.1s;
}
[...]

won't work ...
