No, grapes are not safe for cats. While the specific toxic compound remains unidentified, ingestion can lead to acute kidney failure. Even small amounts pose a serious risk, so you should keep all grapes and raisins strictly away from your feline companion.
🚨 Emergency: Yes — contact your veterinarian immediately.
💡 Why
Veterinary toxicology confirms that grapes and raisins cause acute kidney injury in cats, though the exact mechanism is still unknown. Symptoms often appear 12 to 24 hours after ingestion and include vomiting, lethargy, and decreased urination. Because individual sensitivity varies, there is no known safe threshold for consumption.
🩺 What to do
- Immediately contact your veterinarian or an animal poison control center if you suspect your cat ate any grapes.
- Do not induce vomiting unless explicitly instructed by a professional, as this can cause further harm.
- Bring a sample of the grape or raisin to the clinic if possible to help with diagnosis.
❓ Common questions
Can cats eat raisins?
No, raisins are dried grapes and carry the same risk of kidney failure. They are often more dangerous because they are smaller and easier for a cat to swallow whole.
How much grape is toxic to a cat?
There is no established safe dose. Some cats may react to a single grape, while others might tolerate a few without immediate symptoms, but the risk of delayed kidney damage remains high.
What are the early signs of grape toxicity?
Early signs typically include vomiting, diarrhea, and lethargy within 24 hours. Later stages involve dehydration, loss of appetite, and a significant drop in urine output.
