Can Cats Have Ibuprofen?

No, cats should not have ibuprofen. Human NSAIDs are processed differently in cats and can cause serious toxicity, including gastrointestinal bleeding and acute kidney injury.

Why ibuprofen is dangerous for cats

Ibuprofen blocks prostaglandins that help protect the stomach lining and maintain kidney blood flow. In cats, this can quickly lead to:

• Stomach irritation and ulceration
• Vomiting and bloody stool
• Reduced kidney perfusion and kidney damage
• Severe dehydration and collapse in advanced cases

Because cats are small and metabolically sensitive, even one or two tablets can be dangerous.

Signs of ibuprofen toxicity

Symptoms may start within hours and worsen over 24 to 72 hours:

• Vomiting or drooling
• Poor appetite
• Black, tarry stool
• Lethargy
• Increased thirst or urination changes
• Weakness or collapse

What to do right away

1. Remove access to the medication bottle and count missing tablets.
2. Call your veterinarian, emergency clinic, or poison hotline immediately.
3. Share your cat's weight, product strength (mg), and estimated time of ingestion.
4. Do not induce vomiting unless a veterinarian specifically instructs you.

Veterinary treatment

Treatment depends on timing and dose but may include:

• Decontamination when appropriate
• IV fluids to support kidneys
• Gastroprotectants for ulcer risk
• Bloodwork and urine monitoring
• Hospitalization for moderate to severe cases

Safe alternatives for pain

Never substitute human pain medicine for veterinary medications. If your cat appears painful, ask your veterinarian for cat-safe options tailored to the diagnosis.

Safer pain management usually includes:

• Cat-specific prescription analgesics
• Targeted treatment of the underlying disease
• Dose adjustments for age and kidney/liver status

Keeping all human medications secured in closed cabinets is one of the best prevention steps.
