All animals can be affected by toxins in household products — just in different ways. Dogs like to chew on things like detergent pods, while cats tend to groom substances off their fur. Birds are especially sensitive to airborne toxins, while amphibians absorb toxins through their skin.
Toxicity is often directly related to the concentration of chemicals. Multipurpose cleaners are usually pretty dilute, whereas corrosive products—like oven cleaners — are much more concentrated. Products that are very acidic or alkaline are also more caustic.
Make sure to store household products safely and use them only as directed. As a general rule, keep animals away while you’re cleaning and let them return only when you can’t smell the product anymore.
