Residents in the suburb of Moorooka say they have been scratched, bitten, hissed at and intimidated several times by the feral felines.
Marlene Jans was taking her five-month-old fox terrier for a walk last Monday when two of the huge cats attacked.
"I was crossing the road, it was dark and I couldn't see them," Jans said. "Then, bam! One came at my dog, one came at me. One was biting my leg. I went for my dog because she was screaming.
"I had to kick them away. I was really scared and I was dripping blood."

The local council said it is taking steps to have the cats rounded up. (read more)
