Antifreeze is poisonous to both dogs and cats. Remember to clean any leaks or spills to avoid potential harm. If you suspect that your pet was exposed to a poisonous substance, contact your veterinarian, or the emergency animal clinic if it is after business hours.
Sometimes outdoor cats crawl underneath the hoods of vehicles to sleep near the engine for warmth. It is always a good idea to check before starting your vehicle on cold mornings, especially if you know there are outdoor cats in the area.
