A previously unaddressed provision of Illinois’ animal care law has caused police officers to hesitate before taking steps to rescue suffering dogs or cats, but a bill signed into law last week should change that, experts say. The bill, which took effect Aug. 7, revises the state’s Humane Care for Animals Act to clarify the right of law enforcement to take custody of abandoned or lost dogs or cats that appear to be suffering from exposure to extreme heat, cold or another life-threatening condition.Although the law’s previous version gave police that right, it also required officers to take the animal immediately to an emergency veterinarian and obtain a diagnosis justifying the officer’s decision to take custody.
