Whether they can see in pitch black, I don't know, but they can see well enough on a dark night to get around in the fields. (Says she who has been led a right royal dance by a Jersey who didn't want to come in on the odd occasion...
)
I often wonder about sheep, though - their eyes reflect, so they must be using the available light, but when feeding them in the dark they don't seem to be able to find the cake.
I guess that means their
noses don't work in the dark!
