Clinical and Laboratory Findings of the First Reported Oral Flumethrin Toxicity in a Cat
Abstract
Flumethrin is an ectoparasiticide drug belonging to the α-cyano pyrethroid group, which is a long-acting drug due to its lipophilic structure. Although its absorption after oral administration is slow, its ability to remain in systemic circulation for a long time causes clinical signs to appear later and persist longer. This case report discusses the acute toxicity observed in a cat that ingested a topical preparation intended for dogs and containing flumethrin. The cat exhibited neurological symptoms such as hypersalivation, tremors, and lethargy. Later laboratory findings revealed elevated hepatic enzyme levels. Clinical improvement was observed on day 14 following symptomatic treatment. Haematological and biochemical parameters returned to normal by day 30. This case demonstrates that exposure to pyrethroids may cause serious toxic effects, particularly in cats.
