Really? I didn't know that. What about electric fences for example?

I would have guessed that horses & cattle could have taken larger shocks
than humans because of thier greater mass. How does that work?

I think the major issue is simply that horses and cows are *longer*
than people so even quite small leakage currents into the ground will
cause a large enough voltage gradient to affect them whereas it won't
affect bipeds.

Apparently it's not unusual to find a field of dead cattle, where
lightning has struck the ground and caused a (bovine) fatal pd across
the heart.
