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

On June 29, 2011 the owner noticed the cat was symptomatic. Later that evening, the owner bathed the cat. On the morning of June 30, 2011 the owner took the cat to the veterinarian, and the veterinarian contacted the Animal Product Safety Service (APSS) to obtain help shortly after the cat arrived. The APSS veterinarian stated that Methoprene is an insect growth regulator (IGR) with a very wide margin of safety and that the signs the cat was having would not be expected from the use of the product. The APSS veterinarian discussed the possibility that the cat was inadvertently exposed to Permethrin from another product. The APSS veterinarian recommended that the veterinarian obtain additional information about the product placed on the cat, provide Methocarbamol by injection and send oral Methocarbamol home with the owner, and to call back with questions.

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. On the morning of June 30, 2011 the APSS veterinarian called the regular veterinarian to discuss having hair testing done to test for Permethrin, Etofenprox, and Methoprene. On July 5, 2011 an APSS veterinarian called the regular veterinarian, who stated that on June 30, 2011 the cat was given fluid therapy and, as instructed, was given an injection of Methocarbamol and was sent home with oral Methocarbamol. The regular veterinarian stated that the cat had fully recovered by the evening of June 30, 2011. The regular veterinarian also confirmed that they were having hair testing done. On July 18, 2011 the results of the hair testing were available. The hair testing confirmed the cat was exposed to Permethrin and Methoprene, but not to Etofenprox. On July 21, 2011 the APSS veterinarian called the regular veterinarian's staff to discuss the hair testing results and to request that the regular veterinarian share the information with the owner.
