Ok...I think he would have to run quite fast and very close to ewe so that ewe could not focus as he wooshes by......else....even if he ran at 100mph ewe would still be able to see the differences as you'd still be able to focus...................I think !!!

It depends on how far away the zebra is too. From a large distance they look grey anyway.
I think it's essentially a question of the stripes moving their own size in less time than the eye's persistence of vision. If you get 2 stripes in the same place in less than about 1/16 second they will blur.
