Debunking the Harkness Test. It does not natter if it can consent or not. If its a non human animal its still bestiality. Their not designed to mate, are not biologically compatible, can transmit diseases, can result in injuries since their organs is not compatible, fetishizing animal body parts is creepy and your brain is not hardwired to be attracted to animals. Keep your gross fetishes to yourself and dont justify consensual bestiality with talking animals.
