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

On April 14, 2015 the cat developed pruritus. On April 15, 2015 the owner removed the collar. On April 16, 2015 the cat started vomiting. On April 18, 2015 the cat became lethargic and anorexic. On April 19, 2015 the owner woke up with the cat next to her and when she picked her up the cat was limp (eyes open), so the owner gave the cat some water and then took the cat to the veterinarian where the cat's lethargy became severe, so the cat was hospitalized for treatment. On April 21, 2015 the owner contacted the Animal Product Safety Service (APSS). The APSS veterinarian recommended having the veterinarian call for information since signs are far more significant than what we would expect from this agent. Shortly after, the attending veterinarian called the APSS and stated that on April 19, 2015 the cat was diagnosed with bradycardia, dehydration, azotemia, hyperkalemia, and hypothermia. The attending veterinarian performed some laboratory tests, put the cat on fluid therapy, provided thermoregulation and nutritional support (force feeding a/d). On April 21, 2015 the attending veterinarian gave the cat lactulose and the cat's hypothermia became mild. The APSS veterinarian stated propoxur is a carbamate insecticide that is often used in flea collars for dogs and cats, and when used per label it has a wide margin of safety. The APSS veterinarian also stated that if the collars are chewed or ingested, signs of hypersalivation, vomiting, possibly diarrhea, and ataxia may occur but are usually transient. The APSS veterinarian further stated some animals may have pruritus from the collar, or behavioral changes if they are not used to wearing collars, but severe signs are not expected. The APSS veterinarian recommended continuing treatment and providing symptomatic and supportive care.
