Because they’re such picky eaters, we sometimes think cats know what’s best for them when it’s time to eat. But the fact that they’ll walk away from a piece of bad meat doesn’t mean they’ll bypass an open can of tuna. And that can of tuna can be just as dangerous. In fact, you may be surprised to learn some of the common foods your cats should never eat.
Cats can be addicted to tuna, whether it’s packed for cats or for humans. Some tuna now and then probably won’t hurt. But a steady diet of tuna prepared for humans can lead to malnutrition because it won’t have all the nutrients a cat needs. And, too much tuna can cause mercury poisoning. Remember the saying, “Honest as a cat when the meat’s out of reach.” Your cat will see an open can of tuna next to the sink as a dinner invitation.
Onions, Garlic, Chives
Onion in all forms — powdered, raw, cooked, or dehydrated — can break down a cat’s red blood cells, leading to anemia. That’s true even for the onion powder that’s found in some baby foods. An occasional small dose probably won’t hurt. But eating a large quantity once or eating smaller amounts regularly can cause onion poisoning. Along with onions, garlic and chives can cause gastrointestinal upset.
Milk and Other Dairy Products
What could be wrong with offering your cat a saucer of milk or a piece of cheese? Most cats are lactose-intolerant. Their digestive system cannot process dairy foods, and the result can be digestive upset with diarrhea.
Beer, liquor, wine, foods containing alcohol — none of it is good for your cat. That’s because alcohol has the same effect on a cat’s liver and brain that it has on humans. But it takes far less to do its damage. Just two teaspoons of whisky can cause a coma in a 5-pound cat, and one more teaspoon could kill it. The higher the proof, the worse the symptoms.
