No, ibuprofen is extremely dangerous for cats. Even a single human tablet can cause severe kidney failure, stomach ulcers, or death. It is not safe to eat, chew, or inhale. Keep all human medications locked away and out of reach.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Cats lack the liver enzymes needed to metabolize ibuprofen efficiently, leading to toxic buildup. This causes gastrointestinal bleeding, acute kidney injury, and central nervous system depression. Symptoms often appear within hours but can be delayed, making early detection difficult.
🩺 What to do
- Call your veterinarian or an animal poison control center immediately, even if you only suspect exposure.
- Do not induce vomiting unless explicitly instructed by a professional, as this can worsen esophageal damage.
- Bring the medication packaging to the vet to confirm the exact dosage and formulation.
❓ Common questions
Can I give my cat a tiny amount of ibuprofen for pain?
Never. There is no safe dose of ibuprofen for cats. Use only medications specifically prescribed by your vet for feline use.
My cat licked a pill off the floor. Should I worry?
Yes, contact your vet immediately. Even small amounts can be toxic due to cats' slow metabolism of NSAIDs.
What are the early signs of ibuprofen poisoning?
Look for vomiting, lethargy, loss of appetite, or pale gums. Kidney damage may not show symptoms until it is advanced.

| Pet Poison Helpline | Ibuprofen is an NSAID, and NSAIDs top PPH's list of human medications poisonous to pets: while safe for people, even one or two pills can cause serious harm to a pet, and dogs may develop significant stomach and intestinal ulcers as well as kidney failure. | Ibuprofen is an NSAID, and NSAIDs top PPH's list of human medications poisonous to pets: even one or two pills can cause serious harm, and cats may develop significant stomach and intestinal ulcers as well as kidney failure. | Even one or two pills can cause serious harm (no mg/kg figure given) |
| Merck Veterinary Manual | Ibuprofen is no longer recommended in dogs because it commonly causes gastric ulcers and perforation. Acute single doses of 100-125 mg/kg cause vomiting, diarrhea, nausea, abdominal pain and anorexia; renal failure occurs at 175-300 mg/kg, CNS effects above 400 mg/kg, and doses above 600 mg/kg are potentially lethal. | Cats are susceptible to ibuprofen toxicosis at approximately half the dose that affects dogs. | Dogs: gastric ulceration after 8-16 mg/kg/day for 30 days; acute GI signs at 100-125 mg/kg; renal failure at 175-300 mg/kg; CNS effects above 400 mg/kg; potentially lethal above 600 mg/kg.

| VCA Hospitals | Despite its relative safety in humans, ibuprofen and other NSAIDs can be extremely harmful in dogs, and small doses can cause adverse effects and poisoning. Lower doses cause gastrointestinal irritation and ulceration signs; higher doses can result in liver, kidney, and neurological damage. | In VCA's toxic hazards guide for cats, ibuprofen is named among the human NSAIDs described as some of the deadliest medications for cats because of cats' decreased ability to metabolize them; in toxic doses they can result in kidney failure and stomach ulcers. | — |
