Human Foods That Cats Should Never Eat

The occasional table scrap here and there shouldn’t present a problem for your feline friend, but there are some human foods that cats should avoid at all costs. Here, an Indianapolis veterinarian provides a list.


Contrary to the popular image of a cat lapping up milk from a saucer, most cats are actually lactose intolerant and should not be given dairy products. A tiny sip of milk might not hurt them, but too much will cause upset stomach, diarrhea, and vomiting.

Onions and Garlic

Too much onion or garlic ingested in the system can cause digestive upset or even anemia if consumed regularly. Avoid onions and garlic, both cooked and uncooked.


Most people know chocolate is bad for pets. Theobromine is a compound found in chocolate that is toxic to animals—it can cause heart problems, muscle tremors, and more. Never feed chocolate as a treat!


Alcohol affects cats the same way it affects humans. Yes, cats can get drunk! The only difference is that it will take much less alcohol to affect a cat—a teaspoon might put a cat into a coma, and more could spell death. Always avoid giving your cat alcohol, and keep drinks supervised and away from where your cat could get to them.


Caffeine isn’t good for cats—breathing problems, heart palpitations, and seizures could result from too much caffeine intake. Avoid coffee, tea, energy drinks, and other caffeinated beverages from coming in contact with your feline companion.

Grapes and Raisins

Grapes and raisins are proven to be toxic to almost all dogs, although it isn’t clear why. It’s safest to avoid giving these foods to your cat as well. Keep these products out of reach of your cat.

If your cat ingests something toxic, call your Indianapolis veterinarian right away and take your pet to the veterinary hospital. The quicker you act, the more likely your cat will have a full recovery!
