Foods You Should Never Give Your Cat
Feeding a pet often feels like a way to show affection, but when it comes to cats, many human foods can be harmful or even deadly. Understanding which foods are unsafe is critical to keeping your feline friend healthy and avoiding emergency vet visits.
1. Onions, Garlic, Chives, and Shallots
All members of the allium family—onions, garlic, chives, leeks, and shallots—are highly toxic to cats. They can destroy red blood cells, leading to anemia. Both raw and cooked forms are dangerous, and toxic effects can build over even small, repeated doses.
- Symptoms: Vomiting, weakness, orange or dark red urine, pale gums
2. Grapes, Raisins, Sultanas, and Currants
Though the exact compound responsible is unknown, these fruits can cause kidney failure in cats. Even small amounts may lead to severe illness.
- Symptoms: Vomiting, diarrhea, lethargy, increased thirst
3. Chocolate and Caffeinated Products
Chocolate contains theobromine and caffeine, both of which are toxic methylxanthines. Caffeinated drinks and foods can also cause nervous system damage.
- Symptoms: Hyperactivity, tremors, seizures, abnormal heart rhythms
4. Alcohol and Raw Yeast Dough
Even a tiny amount of alcohol can be extremely dangerous for cats. Raw dough can ferment in the stomach, producing alcohol and gas, which may lead to gastric torsion or coma.
- Symptoms: Disorientation, vomiting, depressed neurological function
5. Milk and Dairy Products
Most adult cats are lactose intolerant. Dairy can cause significant digestive issues.
- Symptoms: Diarrhea, gas, abdominal discomfort
6. Raw Eggs, Meat, Fish, and Bones
Feeding raw animal products exposes cats to harmful bacteria and nutrient imbalances. Raw eggs contain avidin, which hinders vitamin B7 absorption. Bones can cause choking and internal injuries.
7. Fat Trimmings
Cooked or raw fat trimmings may cause gastrointestinal upset and pancreatitis.
8. Dog Food
Dog food lacks the essential nutrients that cats need. Regular feeding may cause taurine or vitamin A deficiency.
9. Tuna (Human-Grade)
While cats love tuna, an exclusive tuna diet leads to nutrient imbalances and possible mercury poisoning.
10. Citrus Fruits
Oranges, lemons, and limes contain citric oils and acids that can cause neurological depression in cats.
11. Avocado
Contains a compound, persin, which can disrupt digestive and respiratory function.
12. Mushrooms
Some wild mushrooms can cause severe neurological and liver damage.
13. Macadamia Nuts, Almonds, and Walnuts
These nuts are high in fat and can irritate the digestive tract or lead to pancreatitis.
14. Salt and Salty Foods
Too much salt leads to electrolyte imbalances and sodium ion poisoning.
- Symptoms: Tremors, seizures, excessive thirst
15. Sugary Foods and Xylitol
While xylitol’s toxicity in cats isn’t fully established, it is best to avoid artificial sweeteners and sugar-laden foods to prevent obesity and dental issues.
16. Tomatoes and Potatoes
When raw, these contain solanine, which may cause severe gastrointestinal distress.
17. Raw Liver
Excessive raw liver intake can lead to vitamin A toxicity, affecting joints and bones.
18. Medications and Foreign Substances
Many human medications and objects like string or small toys are extremely dangerous if ingested.
