The seven-year-old Russian Blue cat was discovered in front of the rear doors of Nootka Elementary School in Vancouver.
Marcie Moriarty, the chief prevention and enforcement officer at the B.C. SPCA, says Smokey died from massive head injuries.
"The cause of death has been determined to be blunt force trauma to the head," said Moriarty. But what is more disturbing than that is that this cat was posed in a very disrespectful manner"
Morarty says the cat was found with his mouth, ears and eyes filled with blood. A smoked cigarette butt was shoved in his mouth and he was intentionally positioned as if standing on his hind legs.
She says the pictures are so disturbing and graphic that they are not releasing them for the public to see.
The B.C. SPCA doesn't know if the posing happened before or after the cat died, but "either way," said Moriarty, "it is exceptionally disturbing and this type of behaviour towards animals is horrific."
Moriarty says the owners of 'Smokey' are traumatized. She says it was hard for them to go public with this story and re-live it, especially on World Cat Day.
"Obviously very traumatic for the owners, and we have been working with the owners. They've done everything right. Their cat had a collar, ID, phone number and up until Friday was in good condition."
The BC SPCA is looking for anyone who has information to call the B.C. SPCA Animal cruelty hotline at 1-855-622-7722.
