The 600V DC on the third rail is enough to seriously burn and often

It has often bemused me that the sides of the tracks aren't littered
with dead cats and urban foxes (not to mention moles on the line).
Does anyone know why?

Having said that, I was once standing on a platform when a fox walked
its length to the footbridge where it crossed over and proceeded down
the opposite platform. Perhaps their mummies tell them.
