Lysol is mainly an eye irritant to humans, but it can have more harmful effects on animals, especially birds. One of Lysol spray's active ingredients, alkyl dimethyl benzyl ammonium chloride or ADBAC, is considered a secondary hepatotoxin and can cause skin burns.
As of 2015, Lysol All-Purpose spray mostly consists of an unspecified detergent, with small amounts of the ammonia-based compound ADBAC. ADBAC serves as an antimicrobial. It can cause irritation if it comes into contact with one's eyes. Cats that accidentally get Lysol on their fur or skin, or ingest it, can experience chemical burns.
This chemical is also known to cause liver damage and chemical burns in rabbits. Birds are very vulnerable to aerosol-based toxins, and Lysol is no exception. Spraying Lysol in the same room as a pet bird, or using it on items the bird comes into close contact with, can cause illness and even death.
