The RSPCA is investigating after piles of raw meat have been popping up on nature strips in Diamond Creek.
There are concerns the dumped raw mince and offcuts are bait for animal poisoning.
Nillumbik Council spokesman Mitch Grayson urged pet owners to be hyper-vigilant in the area and let the RSPCA know if they see anything suspicious.
The Prevention of Cruelty to Animals Act 1986 states:
“Anybody found guilty of animal cruelty under this Act can face fines up to $40,297.50 or 12 months’ imprisonment, or fines up to $80,595 or two years’ imprisonment if the offence results in the death or serious disablement of the animal.”
