What Foods Are Toxic To Cats?
Last update: 05 September, 2018

A common question from cat owners is what foods are toxic to cats or dogs. In this article, you can take a closer look at what foods are toxic to cats. The list below will help you know exactly what foods you should avoid having around your cat. The following are some toxic foods to cats:

  • Caffeine, theobromine, and theine
  • Milk and lactose
  • Alcohol
  • Onions and garlic
  • Salt, sugar, and spices
  • Avocado

Caffeine, theobromine, and theine

Caffeine, theobromine, and theine, or in other words, coffee, chocolate, and tea are very harmful to a cat’s body. They accelerate a cat’s heart rate and can cause vomiting, diarrhea, and other digestive problems. In large doses, consuming these foods can be fatal. Be very careful about leaving these types of food around your cat.

Milk and lactose

There is a popular belief that cats love milk. People believe it’s okay to give them milk during any stage of their lives. This is wrong because adult cats are lactose intolerant. The consumption of dairy products can cause significant digestive problems in cats.


Although this seems obvious, veterinarians can all tell several stories about having to deal with emergency situations due to cats consuming alcohol. By no means allow your cat to consume alcohol because it’s a very dangerous drug and its consumption can be fatal in any kind of pet.

Onions and garlic

Onions, garlic, and leeks, can destroy red blood cells by causing anemia in pets. That’s why it’s important to prevent your cat from eating these foods. Remember, giving your cat leftovers is also probably a bad idea because we frequently use onion and garlic in many dishes.

Salt, sugar, and spices

Salt, sugar, and spices may be part of a human diet, but that doesn’t mean they are good for pets. These foods are toxic to cats and are linked to hypertension, digestive problems, and other diseases that can easily be avoided if you don’t give them to your pet. 


The avocado is a high-fat fruit. These fats are good for humans and are unhealthy for animals. Other than having a large number of calories, avocados contain persin, which is a toxin. Therefore, you should provide your cat with calories from different sources, such as salmon oil.

Some figure


Everyone has seen a cartoon of a kitten gnawing on a fishbone. However, in real life, bones can cause serious problems. They are the main cause of death due to pets choking on them and they’re linked to other problems, such as holes and ulcers.

Depending on who you speak to, the list of dangerous foods could be endless. It’s best for you to seek advice from a trusted specialist before feeding your cat anything new.

If you’re worried your cat may have been eating something toxic for him, you should go to your veterinarian right away. No matter, the best option is that you only feed your cat food that has been specially designed for him, based on his breed, age, and size.
