I am just guessing...but i would guess that was a cow that didn't survive having a cesarean section birth,probably setting outside some veterinarian place waiting for the knacker man to pick her up. And they thought wow!!!! Lets pull a prank with that dead cow..... like i said idk but anyway?Wow, like everyone has said above me, It’s disgusting and an act of animal cruelty. I hope they find the ones involved and prosecute them to the fullest.
