- 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 of permethrin toxicity include vomiting, drooling, lack of appetite, diarrhea, seizures, muscle tremors, lethargy, vocalization, difficultly breathing and, in severe cases, death.
- 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 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.
- Fortunately, the prognosis for cats who receive immediate care is good, and most cats will often recover within 48 hours.
