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

On May 29, 2010 the owner took the cat to the veterinarian where fluid therapy was given. Shortly after, the attending veterinarian contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated cats tend to tolerate etofenprox much better than permethrin. The APSS veterinarian recommended obtaining additional information on other possible exposures, having a diagnostic evaluation completed, supportive care, and calling back with questions.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. Later on May 29, 2010 the attending veterinarian called the APSS back to update the case. The attending veterinarian stated the owner is adamant there is no risk for marijuana or ivermectin, and the house is 30 years old, so probably no risk of lead paint. The APSS veterinarian recommended trying to find out if the cat had been exposed to other medications. The APSS veterinarian recommended bathing the cat with liquid dish washing detergent, administering diazepam and methocarbamol, and monitoring the cat's blood pressure. On June 2, 2010 an APSS technician called the clinic to update an update on the case. The attending veterinarian stated the cat had died the evening of May 29, 2010. The APSS technician recommended a necropsy. Shortly after, a veterinary technician from the attending clinic called the APSS back and stated that the owner had opted not to do the necropsy, as the pet had been buried.
