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

On August 11, 2016 the cat developed symptoms. The owner then took the cat to an emergency veterinarian, where they washed the cat's feet (liquid dish washing detergent (LDWD)), gave fluid therapy, and gave maropitant. On August 12, 2016 the cat still hadn't improved so the emergency veterinarian gave the cat methocarbamol and fluid therapy. Later that day, the emergency veterinarian called the Animal Product Safety Service (APSS). The APSS veterinarian stated with the Zoecon product s-methoprene is an insect growth regulator (IGR). The APSS veterinarian also stated if ingested there could be hypersalivation and nausea. The APSS veterinarian stated with the Prelude product cats do not tolerate permethrin and there are some individual variations in sensitivity. The APSS veterinarian stated signs range from mild parethesia, ataxia, and tremors to seizures and signs can develop from almost immediately up to 72 hours post exposure. The APSS veterinarian stated with the Air Guard piperonyl butoxide and n-octyl bicycloheptene dicarboximide (MGK-264) are synergists to enhance the efficacy of the ingredients and with ingestion expect oral paresthesia. The APSS veterinarian also stated common clinical signs may include gagging, retching, lip licking, increased swallowing, and vomiting from the tingling/burning sensation in the mouth and throat. The APSS veterinarian further stated these signs occur right after exposure and are usually self-limiting. The APSS veterinarian finally stated central nervous (CNS) signs are not expected. The APSS veterinarian recommended monitoring the cat at the veterinary facility for CNS and gastronintestinal (GI) signs, managing vomiting, fluid therapy, complete blood count, chemistry profile, radiographs (examine bullae), and calling back with questions. The APSS veterinarian discussed the case with the attending emergency veterinarian and stated that some of the signs could fit with a paresthesia reaction to the pyrethroids and pyrethrins, but would not expect the nystagmus. The APSS veterinarian recommended if the cat is not improving overnight, would want to look into other causes.
