Coulter said the Humane Society consulted a snake expert who said the snake died at the hands of a human and not another animal. She also said rocks didn't simply fall on the snake and kill it.

"It's a concern because, just because she's not a dog or cat doesn't mean she didn't suffer. She was attacked and left there to die," Coulter said. "If this was a dog or cat pelted with rocks and left to die, everyone would be horrified.

"While snakes may not be everyone's favourite animal, they are a part of our ecosystem and can suffer like any other animal."
