Dr. Schmid assures that diluted automatic toilet bowl cleaners typically won’t cause life-threatening harm to pets, but any household cleaning product carries potential risks—and a pet who drinks from the toilet could get sick from other water contaminants. You can look for non-toxic, green cleaning products specifically labeled as safe for pets. However, Reynolds suggests that the simplest solution to keeping your pet safe is by keeping the toilet lid closed and the door to the bathroom shut. When in doubt about whether your pet ingested something toxic or if they require immediate medical care, veterinary toxicologists can be reached 24/7 at the Pet Poison Helpline at 855-764-7661.
