Household chemicals and cleaning products toxic to pets

Household safety: what to lock away

Garage

Antifreeze (drips on floor), engine cleaner, petrol, pesticides. Clean up any antifreeze drips immediately - a puddle is fatal.

Garden

Slug and snail pellets (high priority - dogs find these attractive), fertilisers with pesticides, organophosphate sprays, rat bait stations.

Kitchen

Cleaning products under the sink, dishwasher tablets, drain unblockers. All should be in a child-proof cabinet.

Bathroom

Toilet cleaner (caps loose after use), bleach, nail polish remover, mouthwash (often contains alcohol or xylitol).

Pet-safe cleaning alternatives

Some cleaning product brands are better formulated for pet households. Look for products that are fragrance-free, bleach-free, and avoid quaternary ammonium compounds (quats) - the active ingredient in many disinfectant sprays that is particularly toxic to cats.

Brands commonly cited by vets as lower-risk: Mrs Meyer's Clean Day, Method, and unscented white vinegar solutions. Always allow floors to dry completely before pets re-enter the room.
