Introduction

Permethrin is the active ingredient of many 'spot-on' paraciticides used in the control of fleas and ticks in dogs [1].

Signalment

Permethrin poisoning in most commonly seen in cats who have inadvertently been administered spot-on products intended for use in dogs, or who have had contact with dogs following application of the preparations [2].

Diagnosis

Clinical Signs

Laboratory Tests

Pathology

The spot-on canine preparations are often quite concentrated.[2]. Cats lack the enzyme glucuronidase transferase [3] and is therefore unable to utilise the metabolic pathway that dogs and other animals use to break down permethrin into glucuronides and sulphates [4]

Treatment

Prognosis
