Many floor cleaning products are safe for pets when used according to the manufacturer's directions. It's worth noting that the ASPCA recommends letting floors dry before allowing pets to re-enter the room. Most floor cleaning formulas have low concentrations of harmful chemicals; however, no floor cleaner is pet-safe if it’s ingested in large quantities. If the thought of your pet's fur and paw pads coming in contact with freshly-cleaned floors gives you pause, choose a non-toxic floor cleaner. There are also many natural cleaning products that rely on plant enzymes, vinegar, and other naturally-derived ingredients for cleaning power (instead of chemicals). These can be a safe choice for pets as well, but be sure to carefully read the labels for each product before making a decision.
