I don't have it to the point of phobia, but I do find images of multiple tiny holes (especially with eye-looking things inside) in animals and plants disturbing.
I think it is indeed a natural response. Animals/plants with lots of tiny holes look diseased to me.
By the way, if you do have this to the point of phobia, don't look at images of the Surinam Toad, whose young grow out of holes in the mother's back. Really, it's nightmarish.
