Cat Ate Ibuprofen: NSAID Toxicity & Renal Perforation Triage
Cats CANNOT take ibuprofen in any dosage. Cats are extraordinarily deficient in hepatic glucuronyl transferase enzymes; a fragment of a single 200mg human tablet causes acute renal necrosis and fatal gastric perforation.
Toxic Mechanism & Agent
Toxic Agent: Ibuprofen (NSAID)
Mechanism of Action: Profound, irreversible suppression of renal prostaglandin synthesis (PGI2, PGE2), terminating renal auto-regulation and precipitating acute medullary ischemic necrosis.
Figure 1: Feline Ibuprofen Toxicity & Renal Papillary Necrosis Exhibit — Macro clinical toxicology display highlighting marked feline sensitivity to NSAIDs due to hepatic glucuronidation deficits. Ingestion triggers swift renal hemodynamic collapse, marked azotemia (elevated BUN/creatinine), and gastric ulceration.
Clinical Signs & Timeline
Onset Time: Vomiting within 1-2 hours; severe acute renal failure within 12-24 hours.
Mandatory emergency hospitalization with 72-hour aggressive IV diuresis. Administration of gastric cytoprotectants (misoprostol, pantoprazole), repeated activated charcoal, and renal hemodialysis if anuric.
Figure 2: Feline Hemodialysis & Critical Renal Triage — Specialized continuous renal replacement therapy (CRRT) and intensive urinary output monitoring for a feline patient in acute oliguric renal failure following accidental NSAID ingestion, providing vital extracorporeal clearance.
Strict Rule S1 Warning
NEVER induce vomiting at home using hydrogen peroxide without direct instruction from a DVM. Inappropriate emesis can cause fatal aspiration pneumonia. Always seek professional veterinary diagnosis.
