Cats are uniquely vulnerable to many household substances including certain plants, foods, and chemicals due to their limited detoxification capacity; awareness prevents preventable welfare harm.
Cats are disproportionately vulnerable to a range of common household substances due to their unique metabolism. The inability to glucuronidate many xenobiotics means that compounds safe for humans and dogs are potentially fatal for cats. The home environment harbours multiple risks that owners may not be aware of: certain houseplants including lilies, human medications, some dog parasite treatments, and common household chemicals. The welfare harm from accidental toxin exposure includes acute suffering from neurological effects, kidney failure, or liver damage, often with fatal outcomes. Prevention through owner awareness is the most effective intervention.
