A teenager has bitten chunks of fur and flesh out of a possum’s rump in one of several disturbing attacks on possums in Queensland.

The RSPCA has shared footage of four attacks, all involving possums, after concerned people found them on social media.

The most disturbing one shows a teenager being egged on by mates in Brisbane as he bites and chews flesh torn from one animal with his teeth.

The mammal’s leg was moving and it appeared to be alive.

In another incident in far-north Queensland, a possum caught in a net is hurled to a waiting pack of dogs that tear it to pieces.

No arrests have been made in relation to the incidents, but police are investigating.

“These are quite deliberate and premeditated acts of animal cruelty and show a complete lack of empathy,” RSPCA Queensland spokesperson Michael Beatty said.

“Without meaning to sound too melodramatic, the links between this type of cruelty and acts of violence toward humans have been well researched over the years.”

The RSPCA also has photos and videos of two other attacks that resulted in charges in February.

One in St George involves a man allegedly dragging a possum from a tree, slamming it into a wall and then throwing it into the bush. He has been charged with animal cruelty and will face St George magistrates court on 12 March.

A 24-year-old woman has also been charged with taking protected wildlife and weapons charges after being pictured proudly posing with rifles and a dead possum. She will face Gympie magistrate’s court on 11 March.

The RSPCA said it was impossible to say if acts of cruelty were on the rise, or if people were just more willing to report it.

The organisation has urged anyone with information about the incidents to contact the police.
