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

On May 10, 2013 the owner noticed that the cat was having tremors. Later that afternoon the owner bathed the pet. The owner also contacted the Animal Product Safety Service (APSS) that afternoon to obtain help; the owner stated that the cat's tremors had become milder. The APSS veterinarian stated that cats do not tolerate permethrin well and that drooling, ataxia, tremors, seizures, and possibly death could be seen. The APSS assistant recommended that the owner provide thermoregulation by towel drying the cat to prevent shivering, take the cat to the veterinarian, have the veterinarian call for information, and monitor the cat at home.

On May 11, 2013 the owner's regular veterinarian contacted the APSS to update the case. The owner's regular veterinarian stated that the cat arrived on the evening of May 10, 2013; the cat's temperature was normal at 102.0 degrees Fahrenheit and the cat's tremors had worsened again. The vet staff gave the cat 5 cubic centimeters (cc) of Methocarbamol intravenously to the cat initially and then gave another 5 cc in water rectally prior to the clinic closing, provided fluid therapy, and bathed the cat. Earlier in the morning on May 11, 2013 the vet staff observed that the cat's pupillary light reflex was absent, the cat was in a coma, and the cat had a corneal ulceration. The vet staff gave the cat 0.4 cc of Diazepam to the cat intravenously. The APSS veterinarian stated that given the cat's condition, there was a grave prognosis for survival. The APSS veterinarian recommended that the regular veterinarian provide symptomatic and supportive care; give a 20 percent (%) solution of intralipid at 1.5 milliliters per kilogram (mL/kg) intravenously over 10 minutes and then give 0.25 mL/kg/minute (min) every 30 to 60 minutes in a peripheral vein, repeating the process every 4 hours if the serum was clear and not discolored; and call back with questions. Later that morning the owner contacted the APSS to discuss the case. The APSS assistant recommended that the owner have her regular veterinarian call for information. A short time later that morning the owner's regular veterinary staff contacted the APSS to get more information and during that time the cat died. A necropsy was not available. This is a dog product and may be fatal when used on cats.
