Don't know about now but in 1988 La Rochelle airport used to have sheep grazing the grass beside the runway. They didn't seem peturbed in the least.
I've done metal repairs to light aircraft that had landing disagreements with various African creatures straying onto bush strips. One (a small gazelle ISTR) dashed across the 'runway' and managed to damage the MLG strut front fairing of an Islander on its landing run without going through the prop.
A buffalo (or some other large beast) wrote off a landing KingAir 200 on another strip, luckily with no human casualties.
