(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.
Death
Generalized pruritus and rash on abdomen are not anticipated with topical product administration. If any, skin reactions would be localized at the application site. Moreover, in this case, these signs are not related with the product as they occurred before product application. Death is not expected either as it is inconsistent with pharmaco-toxicological product profile and experience. Product has wide margin of safety. Oral LD50 in rat 642 mg/kg BW. 24-fold over dosage tolerated by cats without showing any side effect. Animal involved in this case was geriatric with a fair health condition. Also, previous exposure was well tolerated by the animal. Time to onset of 3 month is too long. Overall, even though no necropsy was performed, considering the known safety profile of the product, a product relation is unlikely.
