Horrific cat attack devastates Mandurah family
A Mandurah family says the decapitation of their pet cat, Houdini, was a senseless crime and owner Sharon Anderson has warned others to keep a close eye on their pets.
Houdini had been missing for about two weeks when Ms Anderson discovered his mutilated body in the front yard of her Greenfields home.
“It’s a terrible crime, an act of violence, then to put him back in the yard, it’s just awful,” said Ms Anderson.
Ms Anderson said the pet was loved by her three teenagers.
“The kids are devastated,” she said.
“Houdini would hang around the house with them.
“They loved him.”
Although Ms Anderson doesn’t know what might have prompted the attack, she said she was concerned for other pet owners in the area.
“Hopefully people will be more careful with their cats,” she said.
“At least stop them roaming if you can and keep a close eye on them.”
The family has contacted police and the RSPCA who are investigating the incident.
RSPCA WA chief David van Ooran said he was disturbed and disgusted by the report.
“Animal cruelty is not tolerated by the community and persons guilty of such offences should be prosecuted,” he said.
“The RSPCA has a 24-hour animal cruelty hotline and urges anyone with any information on this or any other act of cruelty to report it on 1300 278 3589.”
Cruelty to animals can attract a penalty of five years in prison and up to $50,000 in fines.
