Permethrin is a synthetic form of pyrethrin, both of which are active ingredients in medications that are used to treat flea infestations; however, permethrin is only for use in dogs due to the highly toxic effects it has on cats.
-
Causes
-
Feline permethrin toxicity occurs when a cat owner uses dog-only flea products on their cat. Symptoms of permethrin toxicity usually occur within six hours of applications.
Symptoms
-
Symptoms of permethrin toxicity include vomiting, drooling, lack of appetite, diarrhea, seizures, muscle tremors, lethargy, vocalization, difficultly breathing and, in severe cases, death.
At-home Treatment
-
Immediate treatment involves bathing the cat in lukewarm water with a mild dish soap to remove as much of the permethrin flea product from the cat's skin.
Veterinary Treatment
-
Veterinary care should be sought immediately to remove any permethrin that has already been absorbed into the cat's body as well as treatment to control seizures and muscle tremors.
Time Frame and Prognosis
-
Fortunately, the prognosis for cats who receive immediate care is good, and most cats will often recover within 48 hours.
