The Lincoln County Humane Society says rat poison has been found scattered in a St. Catharines park.
LCHS received numerous calls that brought them to Alex MacKenzie Park on Beech Street.
Officers attended and found rat poison in a small area of the park.
While the investigation continues, they ask that you keep an eye on your pets and keep them leashed.
If you have any information, you are asked to contact the shelter directly.
