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

On August 14, 2016 the cat developed symptoms. Later that day, the cat had a seizure, then shortly after developed trembling (owner did not say when it started), so the owner then contacted the Animal Product Safety Service (APSS). During the call the cat developed tremors, and warm skin (cat feels hot, but temp is 38.6 degrees Celsius (C) (101.48 Fahrenheit (F)). The APSS assistant recommended the owner take the cat to the emergency veterinarian and have the veterinarian call the APSS to continue the case. The attending emergency veterinarian called the APSS to continue the case and stated the owner bathed the cat. The APSS veterinarian stated may see sensitivity to the collar material. The APSS veterinarian also stated methoprene is an insect growth regulator (IGR). The APSS veterinarian recommended obtaining additional information (any permethrin agents in home?), fluid therapy, monitoring for central nervous system (CNS) signs, methocarbamol (150 milligrams per kilogram (mg/kg) intravenously (IV) to effect; repeat as needed; try to stay below 330 mg/kg/day), monitor body temperature, and provide thermoregulation. The APSS veterinarian also recommended intralipid (recommend 20 percent (%) solution (no brand preference), use peripheral IV catheter, initial bolus at 1.5 milliliter per kilogram (ml/kg) over 5-10 minutes then 15 ml/kg x 30-60 minutes (CRI of 0.25 ml/kg/min), may need to extend CRI volume out longer in smaller patients, Stop IV fluids during this time, repeat in 4 hours (all step 2) provided there is no hyperlipemia, check for hyperlipemia before repeating the dose, do not repeat Intralipid dose if serum color is very orange/yellow; do not repeat until serum has become clearer (check serum color every 2 hours), do not give more than 3 doses if there has been no significant response after giving 3 doses, it may take several doses to see an improvement, there is a low risk of pancreatitis or hemolysis with this medication). The APSS veterinarian also recommended symptomatic care, supportive care, and calling back with questions. The APSS veterinarian called the attending emergency veterinarian to clarify the methocarbamol dosing- should be given to effect. The attending emergency veterinarian stated the cat was given diazepam and methocarbamol (50 mg/kg) and was doing much better. The attending emergency veterinarian did discuss the possibility of permethrin being the cause and the owner did come forth with using some of the dog product.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. The APSS veterinarian stated that permethrin was considered to have a medium likelihood of causing the clinical situation. On August 21, 2016 the APSS assistant called the attending emergency veterinarian to follow-up. The attending emergency veterinarian stated the cat received two doses of methocarbamol and was monitored for 12 hours. The attending emergency veterinarian also stated that when the cat was released he was eating and the trembling had stopped. The attending veterinarian finally stated the owner opted to take the cat home at that time as he could not afford further care.
