(eg. description of the frequency and severity of the symptoms

On October 28, 2017, the cat developed hiding, vocalization, pruritus, and a behavioral change (does not want to be touched, gets a bit aggressive). On October 29, 2017 the owner contacted the Animal Product Safety Service (APSS). A few hours following the call, the cat developed hyperesthesia, agitation, and erythema (at the application site). The APSS veterinarian stated that cats do not tolerate permethrin and that variations in sensitivity depend on the individual. The APSS veterinarian also stated that the risks are for ataxia, tremors, agitation, facial and ear twitching, seizures, hyperthermia, and potentially death if untreated. Finally, the APSS veterinarian stated that signs can develop from almost immediately up to 72 hours post-exposure and that some cats are sensitive enough that casual contact with a treated dog can cause clinical signs. The APSS veterinarian recommended the owner take the cat to a veterinarian, have the veterinarian call for information, and to call back with questions.

19. Provide supplemental information here

This was an inappropriate use of a dog product on to the cat. In the evening on October 29, 2017 the emergency veterinarian called for information. The APSS veterinarian recommended the emergency veterinarian give the cat a bath (Dawn, total body, lather, rinse and repeat), provide vitamin E (apply to application site), give corticosteroid, give diphenhydramine, give maropitant (as needed), monitor for tremors (for another 24 hrs), provide symptomatic care (if tremors develop: methocarbamol. Intralipids if signs are not easily controlled), and provide supportive care. On November 3, 2017 an APSS assistant contacted the owner to follow up on the case. The owner stated that the cat is doing better but signs still continue.
