High amounts of tuna can result in a high concentration of polyunsaturated fatty acids and not enough Vitamin E. This imbalance can lead to a sometimes-fatal condition called pansteatitis.

Onions, Garlic, Chives

Onion can destroy a cat’s red blood cell count – which can lead to anemia. Along with onions, garlic and chives can cause gastrointestinal upset.

Milk and Dairy Products

Many adult cats cannot process dairy food. The result from consumption can be digestive upset and diarrhea.


Alcohol has the same effect on cats as it does on humans – only to a much further extreme. Two teaspoons of whisky can cause a coma in a 5-pound cat, and one more teaspoon could kill it.

Grapes and Raisins

Can cause kidney failure. Repeated vomiting and hyperactivity are early signs.


Can cause death in large enough quantities. Symptoms of caffeine poisoning include restlessness, rapid breathing, heart palpitations, muscle tremors, and fits.


Eating chocolate can cause abnormal heart rhythm, tremors, seizures, and death.

Candy and Baked Goods

Candy, gum, toothpaste, baked goods, and some diet foods are sweetened with xylitol. Xylitol can lead to liver failure. Initial symptoms include vomiting, lethargy, and loss of coordination. The cat may have seizures soon after ingesting the xylitol, and liver failure can occur within just a few days.

Table Scraps

Table scraps often contain fat trimmed off of meat and bones. Both fat and bones may be dangerous for cats. Fat, both cooked and uncooked, can cause intestinal upset, with vomiting and diarrhea. Bones can result in choking, obstruction or lacerations of the digestive system.

Raw Eggs

Can cause Salmonella or E. coli. The enzyme in raw eggs interferes with the absorption of the B vitamin biotin.

Raw Meat and Fish

Raw meat and raw fish, like raw eggs, can contain bacteria that cause food poisoning. In addition, an enzyme in raw fish destroys thiamine, which is an essential B vitamin for your cat. A lack of thiamine can cause serious neurological problems and lead to convulsions and coma.

Dog Food

A steady diet of dog food can cause your cat to be severely malnourished. Small bites here and there wont cause any harm.


Small amounts of liver are ok, but too much can cause vitamin A toxicity. This is a serious condition that can affect your cat's bones. Symptoms include deformed bones, bone growths on the elbows and spine, and osteoporosis. Vitamin A toxicity can also cause death.

Too many treats

Can lead to obesity and diabetes.

Yeast Dough

Can swell in the abdomen and cause severe pain. In addition, when the yeast ferments the dough to make it rise, it produces alcohol that can lead to alcohol poisoning.

Human Medicine

One of the most common causes of poisoning. Always keep out of reach of your pet.

Baby Food

May contain onion powder. Read above for the danger onion’s possess to your cat. Can also result in nutritional deficiencies, if fed in large amounts.

Macadamia nuts

Contain an unknown toxin, which can affect the digestive and nervous systems and muscles.


Can contain toxins, which may affect multiple systems in the body, cause shock, and result in death.

Potato, rhubarb, and tomato leaves; potato and tomato stems

Contain oxalates, which can affect the digestive, nervous, and urinary systems. This is more of a problem in livestock.


String can become trapped in the digestive system; always monitor your cat when he/she is playing with string.


Immediately call your veterinarian if your cat has ingested any of these materials. If you have any further questions, email them to AskMax@CountryMax.com, or visit your local CountryMax store today!
