Bleach

Q: Is Bleach toxic to cats?

Toxic: Toxic — household bleach is a corrosive irritant, not a “tiny lick is fine” product. Sodium hypochlorite bleach burns mucous membranes. Cats walk through mop water or lick a splash, then drool and vomit. Mixing bleach with ammonia or acids creates chlorine gas, which is a lung emergency for everyone in the room. Dilute leftover mop water is still unpleasant; concentrate is worse. Source: ASPCA.

Q: Is Ammonia also safe for cats?

Toxic: Toxic — ammonia fumes and liquid both irritate airways and mouths.
