(eg. description of the frequency and severity of the symptoms
Later in the afternoon on June 14, 2017, the cat developed symptoms. The owner then wiped off the cat's coat with a wet cloth. On June 15, 2017 the tremors had worsened. The owner then gave the cat a bath (without using any soap) and took the cat to a veterinarian. The regular veterinarian then administered fluids (with valium and acepromazine). A few hours later, the regular veterinarian contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated that cats do not tolerate permethrin and that there are some individual variations in sensitivity. The APSS veterinarian also stated that signs range from mild paresthesia, ataxia and tremors to seizures and that signs can develop from almost immediately up to 72 hours post-exposure. The APSS veterinarian further stated that some cats are sensitive enough that casual contact with a treated dog can cause clinical signs. Finally, the APSS veterinarian stated that as long as signs are controlled, prognosis is good. The APSS veterinarian recommended the regular veterinarian bathe the cat (using liquid dish washing detergent (LDWD), give methocarbamol (first dose 50-75 milligrams per kilogram (mg/kg), either by intravenous (IV) injection or per rectum; can add about 30 mg/kg increment after an hour if still marked tremors; keep running tally on total dose in mg/kg), provide thermoregulation (keep warm, becoming hypothermic will potentiate the pyrethroid signs), monitor at the veterinary facility, provide fluid therapy (consider IV fluids if marked tremors, concern for myoglobinuria damaging renal tubules), and to call back with questions.
Moderate
On June 16, 2017 the APSS veterinarian called to follow up on the case. The regular veterinarian stated that the cat was doing well and asked if the cat needed another bath. The APSS veterinarian stated that if the cat is doing well, another bath is not needed. This was off label use, applying the dog product on to the cat.
