9 Foods Cats Can’t Eat

9 Foods Cats Can’t Eat

by Scritch

Cats are obligate carnivores, which means meat must be a regular part of their diet to get the nutrition they need. The digestive system of a cat is adapted to eating raw meat and it is unable to make certain vitamins that humans, dogs, and rabbits can. So what human foods are bad for cats? Some cats may be curious to try new foods and you might be tempted to share a little nibble of your cucumbers as you snack on them. The good news is that several fruits and vegetables are safe to share with cats in small amounts. However, there are many foods you should never allow your cat to eat. 


It shouldn’t come as a surprise that alcohol isn’t good for pets. Consuming even a little bit of alcohol can poison your cat, so keep the cocktails well out of reach. Alcohol consumption can cause vomiting and diarrhea, as well as severe liver and brain damage.

Grapes, raisins, currants

Exactly what makes these fruits toxic to cats (and dogs) remains unclear but ingesting even small amounts can lead to kidney failure. Your best bet is to take your kitty to the vet if you suspect she ate any grapes, raisins, or currants, but you can also watch for signs like vomiting, diarrhea, lethargy, reduced appetite, abdominal pain, and decreased urination.

Yeast dough

Whether you’re making bread or pizza, raw dough is dangerous to cats if it contains yeast. Not only can it expand inside their stomach and cause a blockage, yeast dough also produces alcohol and carbon dioxide.


Contrary to popular cartoons, it is not a good idea to give your cat a bowl of milk. Their ancestors did not seek out the milk of other animals and yours doesn't need milk either. Dairy products are unhealthy for cats and can cause digestive issues like vomiting and diarrhea.

Onions, garlic, chives

These vegetables are part of the allium family and contain a toxic compound that damages the red blood cells and can ultimately lead to anemia. Onions, garlic, and chives are toxic regardless if they are raw, cooked, or powdered. Additionally, your cat shouldn’t eat any foods that have been cooked with these ingredients. 


It’s common knowledge that chocolate is bad for dogs, but it is also just as dangerous to cats for the same reasons. Chocolate contains caffeine and theobromine which can cause vomiting, diarrhea, heart problems, muscle tremors, or seizures. The darker the chocolate, the more poisonous it is to your cat. 


Coffee, soda, tea, supplements, and other items that contain caffeine are off limits for cats. Caffeine can cause harmful effects to your cat’s nervous system, increase her heart rate, and cause seizures.

Fat trimmings

The fat trimmings from cooked or uncooked meats as well as other fatty foods such as french fries are unhealthy for your cat and she shouldn’t eat them. Consuming fatty foods can cause serious digestive upset, including vomiting, diarrhea, and gastrointestinal problems. 

Dog food

Though dog food is not poisonous to cats, it is not formulated for a cat’s nutritional needs. A bite of dog food won’t hurt your cat, but eating a diet consisting of only dog food will cause your cat to become malnourished.
