Cats are uniquely susceptible to many common household toxins due to their deficient glucuronidation pathway, making owner awareness of feline-specific toxins an important welfare intervention.
Toxin exposure in cats causes acute and often severe suffering from organ failure, neurological signs, and systemic illness. Many toxins cause irreversible damage before owners recognise the connection between exposure and illness. Paracetamol ingestion causes severe methaemoglobinaemia with breathing difficulty and chocolate-brown mucous membranes before death. Lily ingestion causes acute kidney failure within 24-72 hours. Owner awareness of the specific toxins dangerous to cats, and immediate veterinary contact when exposure is suspected, prevents significant preventable suffering.
