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

On approximately 29Mar2016, the cat developed generalized pruritus and rash on abdomen. On 12Apr2016 the collar was removed. The cat was not seen by a veterinarian and the clinical signs continued. Follow up received (29th Aug 2016): On an unknown date post collar application, in approximately May-2016, the cat had 1 tube of Advantage II Large Cat (Imidacloprid-Pyriproxyfen) topically by the owner. On an unknown date in 2016 the owner used an unknown carpet spray flea treatment. Approximately 3 months post Advantage II Large Cat, in Aug-2016, the cat died. The cat was not examined by a veterinarian and it was unknown if a necropsy had been preformed. No further information expected. This case is closed. Note: Previous exposure was well tolerated by the animal.

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


19. Provide supplemental information here

Generalized pruritus and rash on abdomen are not expected with topical product administration. If any, skin reactions would be localized at the application site. The animal had a concomitant medical condition of allergic dermatitis which likely contributed to the reported skin reactions. Time to onset is exceptionally long. Reported death is not anticipated after product application as it is inconsistent with products pharmacological profile. Oral exposure to the collar is not expected to cause serious signs either. Moreover, death occurred long time after collar removal. Animal involved in this case was geriatric with a fair health condition. Also, previous exposure was well tolerated by the animal. Overall, even though no necropsy was performed, considering the known safety profile of the product and the chronology, a product relation is unlikely.
