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


19. Provide supplemental information here

Vomiting and diarrhea are unspecific signs and may have many potential causes. Oral ingestion of product was not observed. Even with oral product exposure sign would not be expected, but rather salivation. Anorexia might be a consequence of reported digestive signs. Later reported respiratory depression, jaundice and death are not expected after product application, as they are inconsistent with pharmaco-toxicological product profile. No signs of allergic/anaphylactic reaction reported. Product has wide margin of safety. Oral LD50 in rat is 642 mg/kg BW. 24-fold overdosage tolerated by cats without showing any side effect. In this case cat might have died due to ongoing medical condition. Considering over all too long time to onset, a product relation is deemed to be unlikely.
