THE RSPCA is investigating a string of attacks on animals across the Sunshine Coast, fearing bored children on school holidays could be to blame.
In the past six months nearly 20 native animals and birds have been shot with arrows across the state, with at last two cases recorded on the Coast.
The attacks increase during school holidays.
Recently, a cat was shot with an arrow at Maroochydore, while baby magpies were shot with a nail gun on Bribie Island.
In the latest attack, a dead cat was tied to a traffic sign beside a busy road in Caboolture.
The sight horrified hundreds of passers-by, including 16-year-old local Emily Furnell.
She and her mother were driving along busy Caboolture River Rd on Thursday afternoon when they discovered the sick act.
"I noticed there was something taped to the koala crossing sign pole. It looked to be some bark off a tree in the shape of either a possum or a cat," Emily said.
"We found it was a dead cat which had been tied to the pole with black insulating tape at about head height."
A stunned Emily and her mother contacted the RSPCA.
"I was horrified," Emily said.
"I've had a cat for 11 years and I can't believe some one would do that to an animal."
RSPCA Queensland spokesman Michael Beatty said tying the cat's body to a pole was a disgusting act, even if it had been killed by a car.
"At this time of the year, sadly, we do see more incidents either of obvious animal cruelty or suspected animal cruelty," he said.
"Why anyone would get their kicks from shooting a defenceless creature is beyond us.
"In the case of the cat at Caboolture, all we can do is wait for the results of an aut opsy to find out how it actually died before we decide on what action to take."
Mr Beatty said if children were responsible for the attacks, it raised serious concerns about their future.
"Sadly, the links between acts of animal cruelty at an early age and other forms of violence towards humans down the track are well documented," he said.
The maximum penalty for animal cruelty is $100,000 or two years in prison.
Police are still investigating the bashing deaths of two alpacas at Caboolture High School in October.
