“The Romans used to torture people by having goats lick their feet. Goats like salt, so they would soak their feet in salt water. Eventually the goat’s tongue was rough enough that the skin would wear away; then you’d have a wound with salt trickling in.”
I don't think the Romans gave a f@#k about animals. They definitely gave a shit about humans. Reading about the stuff Roman emperors used to do for giggles is pretty gnarly stuff.
