Human Foods That Are Poisonous to Cats

Human Foods That Are Poisonous to Cats – Cats may seem to beg for human food when they see you eating, but feeding them human food should not be encouraged for several reasons. First, cats need the nutrients specific to them in premium cat foods, so any extras they consume can take away their appetite for their regular meals.

Additionally, there are many human foods that are toxic to cats, which can be life-threatening. As a responsible cat owner, it is important to familiarize yourself with these foods to keep your cat safe.

Human Foods Are Not Safe for Cats

Feeding cats “people food” should be discouraged because there are many foods that are toxic to them, even if they are harmless to humans.

Foods That Are Dangerous for Cats

Green Tomatoes and Raw Green Potatoes

These foods contain a poisonous alkaloid called Glycoalkaloid Solanine, which can cause violent lower gastrointestinal symptoms in cats. It’s important to note that pre-made cat foods that include ripe tomatoes should not be a concern.


Theobromine is a substance found in high concentrations in chocolate, which can cause chocolate toxicity in cats. Dark and unsweetened chocolate are particularly dangerous.

Grapes and Raisins

The toxicity of these foods has mainly been found in dogs, but the ASPCA advises avoiding them for cats because their toxic potential is still unknown. It’s best not to risk it and keep these fruits away from your cat.


Avocado contains Persin, which can cause vomiting and diarrhea in cats. It’s also high in fat, which can lead to gastroenteritis or pancreatitis. Be aware of guacamole and keep it away from your cat.


Alcohol is toxic to cats, and even a small amount can be lethal. Keep alcoholic beverages and other sources of alcohol, such as hand sanitizer or mouthwash, away from your cat.

Onions, Garlic, & Related Root Vegetables

Onions and garlic contain substances that can damage red blood cells in cats, causing a form of anemia. Cats should not consume a full clove of garlic or any large pieces of raw onion. Powdered forms of these vegetables, found in chips, soups, and seasonings, can also be dangerous for cats.

Other Foods to Avoid

While these foods are not toxic to cats, they should still be avoided. Meat trimmings, raw eggs, and caffeinated beverages should not be given to cats. Although milk isn’t toxic, many cats are lactose-intolerant and can experience stomach upset, cramps, and gassiness. Xylitol, an artificial sweetener, is toxic to dogs and may also be toxic to cats.

What to Do If You Think Your Cat Has Been Poisoned

If you suspect that your cat has been poisoned, contact your veterinarian, the ASPCA National Animal Poison Control Center, or Pet Poison Helpline immediately. Share any relevant information, such as what they ate and the symptoms you are seeing. You may be charged for speaking with the poison control line.


  • While it’s best for cats to eat cat food, these “human” foods are safe for your cat: thoroughly cooked lean meats that haven’t been seasoned with onions or garlic, fish with the bones removed, hard-cooked eggs, whole grains, fruits, and vegetables.
  • To prevent cats from eating human food, never offer it to them, even just “licking the plate.” Keep human food out of reach in your kitchen, including covering it on the countertop while you’re eating.
  • Cats like human food because it offers more variety than their regular cat food, and because it tastes good to them.

If you have a health-related question or suspect that your pet is sick, always consult your veterinarian. They have examined your pet, know its health history, and can make the best recommendations for your pet.
