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

Advantage Multi 18 was applied to a 2.5 year old, 13 pound Domestic Shorthair on 4Oct11. This was not the first time application of the product. The cat presented at the veterinary clinic on 7Oct11 for urinating all over the house and acting very hyperactive and "strange." On approximately 9Oct11, the owner found the cat deceased. It should be noted that the cat did have access to the outdoors. A necropsy is pending. 20 Oct 2011: Receipt of technical assessment "The complained batch was manufactured and released according to specification. No deviations occured which lead to the complained AE. " Follow-up, 24Oct11 - The clinic reports they have a low suspcion that the clinical signs were product related. The necropsy results are listed below: General results: Kidney - Fatty vacuolation of the majority of cortical tubules is present. Acute tubular degeneration is observed in some clusters of tubules, characterized by increased eosinophilia, and hyalinity, with cytoplasm taking on a granular appearance and loss of nuclear detail. Tubular lumina occasionally contain proteinaceous casts. Lung - Vascular congestion and edema are pronounced. A large pulmonary artery is occluded by an organized thrombus. Liver - Extensive expanses of hepatic parenchyma exhibit acute hepatocellular necrosis, with preservation of cellular outline, but loss of nuclear and cytoplasmic detail. Histologic diagnosis: Acute tubular nephrosis. Fatty degeneration, kidney. Pulmonary thrombosis. Hepatic infarction. Follow-up, 8 Nov 2011: Further information revealed the involved product was actually Advantage II Large Cat, and not Advocate as originally reported.

To be determined by Registrant

18. Severity classification (if there is more than 1 possible classification


19. Provide supplemental information here

Signs and particularly fatal outcome not anticipated with appropriate topical product administration as inconsistent also with Advocate's pharmaco-toxicological profile. Onset time of 3 days not suggestive of product involvement either. Product used before on cat without causing any signs. Sudden death probably not product related but caused by other underlying health problems or intoxication, as cat had access to outside. Technical evaluation not indicative of product involvement. Necropsy results suggested other etiology for death (acute tubular nephrosis, pulmonary thrombosis, heaptic infarction, acute fatty degeneration of kidney). Thus, relation to Advocate which was finally reported as used product unlikely.
