Permethrin toxicosis in cats.

A retrospective analysis of all adverse experience reports received by the Australian Pesticides and Veterinary Medicines Authority's Adverse Experience Reporting Program for veterinary medicines since 1995, showed that permethrin toxicity in cats usually occurred after the owner applied a canine permethrin-containing product, typically a spot-on. Cats are also at risk from grooming or being in direct contact with recently treated dogs. This paper reviews permethrin toxicosis and its treatment in cats, incorporating information from the Australian and selected overseas veterinary pharmacovigilance programs.
