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

On July 12, 2016 the cat developed pruritus and scabs (owner also said something about sores/lesions). The cat then developed erythema and the owner applied hydrogen peroxide (H2O2) (has been applying 3 percent (%) H2O2 on a cotton swab to the irritated site almost once to twice a day). On July 15, 2016 the cat developed diarrhea. On July 16, 2016 the cat began hiding and was lethargic, but the pruritus seemed mild. On July 19, 2016 the cat developed inappetence and hypodipsia. On July 20, 2016 the cat developed heavy breathing. On July 21, 2016 the cat developed retching. Later that morning the cat's heavy breathing became worse. The owner then contacted the Animal Product Safety Service (APSS). The APSS veterinarian stated etofenprox is an ether pyrethroid, the LD 50 is over 40,000 milligrams per kilogram (mg/kg) (Ag Chem). The APSS veterinarian also stated he would not expect any serious systemic effects from this insecticide with this type of exposure. The APSS veterinarian further stated in general, dermal application may cause a tingling sensation that results in ear twitching, hiding, hyperactivity, etc. The APSS veterinarian finally stated significant neurologic signs are not expected with the appropriate use of etofenprox in cats. The APSS assistant recommended taking the cat to the veterinarian and having the veterinarian call for information.
