See the alphabetical list below for the foods to avoid giving your cats:
Alcohol: Alcohol has the same effect on a cat’s brain and liver as it does to humans but it takes far less to see the effects. As little as a teaspoon can cause a coma in a cat and it can easily cause severe liver or brain damage. The higher the proof of alcohol, the worse the symptoms will be.
Chocolate: Although most cats won’t eat chocolate on their own, you should not attempt to try to feed it to your cat. Chocolate contains theobromine, a chemical found in all chocolate including white chocolate, which is toxic to cats. Eating chocolate can cause abnormal heart rhythm, tremors, seizures, and even death. Dark and semisweet chocolate are the most dangerous.
Coffee/Caffeine: Along with chocolate, coffee contains caffeine. This can cause vomiting, diarrhea, muscle tremors, and can be toxic to the heart and nervous system.
Fat Trimmings and Bones: Don’t feed your cat table scraps. Fat, when cooked or uncooked, can cause intestinal problems, vomiting, diarrhea, or pancreatitis (inflamed pancreas). Cats can choke on bones or the bones can splinter and cause an obstruction or internal lacerations. You should also never give them anything that is as hard as or harder than their teeth because it can cause dental fractures.
Fish: This includes raw, canned, and cooked fish. You can get away with small amounts of fish but if fed in high amounts your cat can develop a thiamine (a B vitamin) deficiency that leads to loss of appetite, seizures, and maybe death. The exception to this is if the fish is made into cat food. Most good cat food brands are supplemented with thiamine are just fine.
Grapes and Raisins: Although it is not known what makes grapes and raisins toxic, they can cause kidney failure. Even a small amount can make a cat sick and cause them to repeatedly vomit and be hyperactive.
Macadamia nuts: Like grapes and raisins, it is not known what makes macadamia nuts toxic. Ingestion of macadamia nuts can affect the digestive and nervous systems and muscle.
Milk/Dairy Products: Surprisingly most cats are lactose-intolerant, so it’s best to be safe and avoid any dairy products.
Mushrooms: Some types of mushrooms contain toxins that can affect multiple systems in the body and cause shock or result in death.
Onions, Garlic, and Chives: Onion, in any form, can cause a cat to become anemic because it breaks down red blood cells. Even the onion powder that is in some baby foods is bad for cats. Onion, along with garlic and chives, can also cause gastrointestinal upset.
Raw eggs and meat: Raw eggs contain an enzyme called avidin, which decreases the absorption of biotin (a B vitamin) and can lead to skin, hair, and coat issues. Raw eggs may also contain Salmonella or other parasites. Raw meat may contain Salmonella and E. coli which can cause diarrhea and vomiting.
Sugary foods: Sugary foods, such as candy and gum, are usually sweetened with xylitol. Xylitol is known for increasing insulin production which causes blood sugar levels to drop. It can also cause vomiting, fatigue, loss of coordination, and eventually liver failure. Even if the sugary food doesn’t contain xylitol it can still lead to obesity, dental problems, and diabetes.
Yeast dough: Yeast dough can expand and produce gas in the digestive system. This can lead to pain and a possible rupture of the stomach or intestines. Additionally, when the yeast causes the dough to rise, it produces alcohol that can lead to alcohol poisoning.
Non-food items: Foreign objects such as toys, soft rubber objects, stringy objects (thread, yarn, tinsel), coins, and medicine are perhaps a greater risk to cats than food. Aspirin, Tylenol, and Motrin are all highly toxic and a single tablet could be lethal.
If you suspect your cat ate any of these foods, first try to determine what and how much he or she ate. You should then call us or your veterinarian to see if medical attention is needed. If a veterinarian is not available, call either Animal Poison Control at 888-426-4435 or the Pet Poison Helpline at 800-213-6680.
Do you have a dog? Most foods that are toxic for cats are also toxic for dogs.
