(eg. description of the frequency and severity of the symptoms
On June 26,2007 at 3:00 pm, CDT, the owner went to check on the cat and found the cat had died. On June 26, 2007 at 4:00 pm, CDT the owner took the cat to her regular veterinarian. According to the owner her regular veterinarian performed a necropsy and found that the cat had an excessive subdural hemorrhage. The APSS veterinarian explained to the owner that the shampoo is not expected to cause neurologic signs-the concentration of pyrethrin in it is not high enough. The APSS veterinarian told the owner that they suspected the vet was confusing neurologic signs, such as tremors and seizures, with permethrin, which is a common ingredient in OTC (over the counter) dog flea treatments. This shampoo does not contain permethrin, and even concentrations of permethrin <1% are not expected to cause seizures. The APSS veterinarian also discussed with the owner that the sequence of events leading to the death also is not expected, even with permethrin toxicity-usually ataxia and tremors are seen first. The APSS veterinarian told the owner that they wouldn't expect a cat to die within 1.5-2hrs of exposure to a permethrin based product.
Death
APSS stated would not expect neurologic signs from pyrethrins with concentration less than 1%. Death of the animal is also not expected. The APSS veterinarian also recommended that a full necropsy (including histopathology and toxicology screening) be done to determine the cause of death in the cat. The owner declined. The APSS states the product have doubtful likelihood in causing the clinical situation.
