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

On May 10th 2017, two day after the product was applied, the owner began to observe symptoms. On May 12, 2017 the owner took the cat to their regular veterinarian who gave the cat a bath twice (using liquid dish washing detergent (LDWD), gave diazepam, ran a chemistry profile (all normal), gave fluids (subcutaneously twice, dispensed fluids for owner to administer), gave methocarbamol (by mouth (PO), and gave phenobarbital. The regular veterinarian stated no tremors were perceived on examination. On May 15, 2017, the regular veterinarian contacted the Animal Product Safety Service (APSS) on behalf of the owner. The APSS veterinarian stated that imidacloprid is an insecticidal agent that has a wide margin of safety in mammals. The APSS veterinarian also stated that it kills insects by binding to the nicotinic acetylcholine receptors in the insect nervous tissue, which are much more prevalent than in mammals. The APSS veterinarian stated that signs were not consistent with the product used and that the signs do not sound like permethrin, either. The APSS veterinarian recommended referral to the manufacturer.

19. Provide supplemental information here

The APSS veterinarian stated that the substance was considered to have a doubtful likelihood of causing the clinical situation. On May 23, 2017 an APSS technician called to follow up the case. The regular veterinarian stated that on May 19, 2017 the cat was euthanized. On May 24, 2017 an APSS technician contacted the regular veterinarian regarding a necropsy. Because the cat was frozen for five days, a necropsy would be unproductive. The APSS technician recommended a permethrin hair test. At the time of this report, the results are still pending.
