The RSPCA is investigating hundreds of incidents of cruelty including cases in which animals have been bashed, tortured and kicked.
In the six months since November last year, inspectors have been called out to 261 reports of deliberate and malicious beatings of animals.
The reports related to incidents within the Perth metropolitan area.
The figure is up from 127 cases for the previous six months.
“This is shocking and deliberate cruelty which, if the animal survives, can have devastating and long lasting effects on the animal,” RSPCA Chief Inspector Amanda Swift said.
Inspectors say the attacks are caused by anger management and personal issues, mental health issues, ignorance and a lack of empathy and compassion.
“No excuse or reason is acceptable for the deliberate cruelty to animals that we are seeing and those that are caught will find themselves in trouble with the law," Ms Swift said.
"What is encouraging is that more and more people are not tolerating cruelty and are not afraid to report it."
Recent incidents include two separate occasions of school yard chickens being beaten and killed and a 15-year-old dog whose legs were snapped by intruders.
Most incidents not reported in the media because of legal restraints when preparing cases for prosecution and the intensely graphic nature of many cases.
The RSPCA has seven disturbing prosecution cases about to go before the courts and several ongoing investigations.
Since July 1 last year, the RSPCA has received an average of more than 60 calls a day to its animal cruelty hotline.
“While our work is often challenging and upsetting, we are regularly rewarded by seeing rescued animals successfully rehabilitated and finding new loving homes via RSPCA’s rehoming program,” Ms Swift said.
People wanting to report animal cruelty can call the RSPCA’s Cruelty Line on 1300 278 3589.
Those wishing to join the Walk to Fight Animal Cruelty are encouraged to participate in the Million Paws Walk being held across the State this Sunday.
