Can Cats Eat Raisins

No — cats must never eat raisins. Raisins are dried grapes and are highly toxic to cats, capable of causing acute kidney failure even in very small amounts. Raisins may actually be more dangerous than fresh grapes because the toxic compounds are more concentrated. This is a critical food safety warning every cat owner needs to know.

Why Raisins Are Toxic to Cats

The exact toxic compound in grapes and raisins has not been identified, but the effect is well-documented: raisins cause acute kidney failure in cats and dogs. Raisins are particularly dangerous because:

• More concentrated than grapes: Drying concentrates whatever toxic compound is present, making raisins potentially more dangerous per gram than fresh grapes
• No safe amount: Even a single raisin could potentially cause kidney failure in a cat
• Unpredictable toxicity: Some cats may appear unaffected initially while kidney damage progresses silently
• Hidden in many foods: Raisins appear in trail mix, granola, cookies, bread, cereal, and many other common foods

Symptoms of Raisin Toxicity in Cats

Symptoms typically appear within 6-12 hours of ingestion:

• Vomiting (often the first sign, may contain raisins)
• Diarrhea
• Lethargy and weakness
• Loss of appetite
• Abdominal pain or tenderness
• Decreased or no urination (sign of kidney failure)
• Increased thirst initially, then decreased urination
• Tremors or seizures in severe cases

Emergency Response: What to Do Immediately

If your cat eats even one raisin, treat it as a veterinary emergency:

1. Do not wait for symptoms — kidney damage can occur before symptoms appear
2. Contact your vet or emergency animal hospital immediately
3. ASPCA Animal Poison Control: (888) 426-4435
4. Pet Poison Helpline: (855) 764-7661
5. Note the amount eaten and the time
6. Do not induce vomiting unless specifically instructed by a vet

Treatment within 2 hours of ingestion (before absorption) significantly improves outcomes and may prevent kidney damage entirely.

Hidden Sources of Raisins

Raisins appear in many common foods that may be left within a cat's reach:

• Trail mix and granola
• Raisin bread and bagels
• Oatmeal raisin cookies
• Fruitcake and Christmas pudding
• Cereal (many brands contain raisins)
• Energy bars and snack bars
• Stuffing and savory dishes with raisins
• Rum raisins in desserts

Keep all of these foods completely secured and out of reach of your cat.

Currants and Sultanas Are Also Toxic

Currants (black, red, and white) and sultanas are also members of the grape family and carry the same toxicity risk. Treat them with the same caution as raisins.

Safe Treat Alternatives

For safe, cat-appropriate treats, always choose protein-based options. Stella & Chewy's Freeze-Dried Raw Cat Dinner Morsels and Blue Buffalo Wilderness Crunchy Cat Treats Salmon Flavor are made with natural ingredients specifically formulated for cats — no toxic ingredients, no guesswork.

Final Thoughts

Raisins are one of the most dangerous foods for cats — potentially more toxic than fresh grapes due to concentration. There is absolutely no safe amount. Keep all raisins and raisin-containing foods completely away from your cat, be aware of hidden sources, and seek immediate veterinary care if any amount is ingested. Don't wait for symptoms.
