Top FDA ADE-report active ingredients by Cat reports
Source: openFDA animalandveterinary/event.json, the FDA Center for Veterinary Medicine (CVM) adverse event report database. The Cat report counts below are the Cat subset of each drug's overall ADE report total, taken from the 2026-08-16 openFDA species-distribution slice. Counts are report-level: one report may list multiple animals and reactions, so figures are not additive and do not imply causation. Ranking is by Cat report volume among the top active ingredients monitored.

Honest scope note
Report counts reflect voluntary adverse-event reporting volume, not incidence or per-animal risk. Many of these drugs are companion-animal parasiticide or NSAID products whose Cat use dominates their reporting. Other species and reports with no species listed are excluded from the per-species figures. Source JSON: pdf-raw/ade/ade_active_ingredients_2026-08-16_b1.json.
