What foods are dangerous for cats, or not recommended?

Are you sometimes tempted to share your meal with your cat? Even if it’s with a good intention, it might be better to avoid doing it, without knowing exactly what’s on your plate. Indeed, toxic foods for our little felines are hidden in our human diet.

Knowing about these dangerous foods for cats is very important to avoid serious poisoning! Let’s find out together which foods are considered dangerous or toxic for cats, and which good practices to adopt on a daily basis.

Can you give your cat any food?

We often tend to think that our pets, so close to us, can eat the same thing as us. However, this is completely false!

The cat is a strict carnivore, which means that in nature it feeds almost exclusively on meat and fish. His digestive system and metabolism are very different from those of a human. Foods that are harmless to us can be toxic to him, and even deadly depending on the amount ingested.

Therefore, do not give leftover meals to your little companion, if you do not know the foods that can be bad for his body. Your feline must be fed animal food specifically intended for cats.

Foods not recommended for cats

Toxic foods aren’t the only ones that pose a health risk to your little feline. Other foods, without posing an immediate danger, can be difficult to digest and make your cat sick.

Dairy products

We all have in mind the image of Épinal of a kitten happily lapping up a bowl of milk. But, in reality, can we give milk to cats? The answer is that it is better to avoid. The kitten must be fed with its mother’s milk, but as it grows it loses the ability to digest lactose.

Milk therefore causes him digestive problems such as vomiting, diarrhea and flatulence. In addition, even if your cat seems to tolerate milk well, it is a food that is too fatty and caloric in nature and risks causing excessive weight gain.

Fat food

Consumption of very fatty foods such as French fries leads to obesity in cats. They can also be poorly digested, and cause stomach upset. In extreme cases, the cat develops pancreatitis which can be fatal.

Legumes and cabbage

These hard-to-digest foods cause bloating and diarrhea.

Tuna and other canned fish

Cats love canned tuna, but it should still be an exceptional treat. Indeed, this food is too salty for the kidneys of our little felines. In addition, it does not contain taurine, which is essential for good heart health.

Recommended foods for cats

The best way to protect your cat from poisoning is to provide it with quality food in the right amount. That way, he won’t be tempted to steal the contents of your pantry or snack on foods that aren’t good for his body. But then, what to feed your cat?

Premium quality croquettes and pâtés

The easiest way to provide your cat with everything it needs without risking poisoning is to feed it with kibble and cat food. Choose premium quality products. They are perfectly suited to your cat’s metabolism due to their high meat or fish content.

This distinguishes them from first price kibbles which contain large amounts of cereal. In addition, premium croquettes and pâtés provide essential amino acids for the good health of your cat.

Be sure to choose products that are appropriate for your cat’s age and health. There are kibbles for kittens, for senior cats, for sterilized cats, for those who suffer from urinary problems…


Catnip is a plant that cats can eat to purge themselves. It promotes digestion, prevents the formation of hairballs and helps the cat to regurgitate the balls already formed. You can therefore leave a pot of catnip available to your little feline, he will nibble on it when he feels the need.

Note: catnip or catmint should not be confused with catnip. It is a plant with euphoric effects, which causes a very pleasant state in the cat. You can therefore give it to him from time to time, for pleasure and not for digestion!

Natural treats

If you want to offer your cat a little sweetness, opt for natural treats. These foods are often pieces of dried meat, and are perfectly suited to the delicate organism of your little feline. You can also occasionally offer him a cat biscuit.

The cooked meat

If you run out of food for your little cat, you can always give him cooked meat or fish. It is also possible to add well-cooked rice in small quantities (no more than 15% of the ration), as well as certain cooked vegetables up to 15% of the ration as well (zucchini, carrots, peas, sweet potato) .

What if my cat has eaten one of the poisonous foods?

When you notice that your cat has consumed a toxic food, the first instinct is to contact a veterinarian. It will tell you the symptoms you need to watch out for. Do not try to make your cat vomit. You risk aggravating his condition.

If your cat has consumed this food in very small quantities and does not show any of these symptoms within hours, just make sure that he no longer has access to the forbidden food.

On the other hand, if your cat develops symptoms or has ingested a large quantity of this food, do not wait before taking him urgently to the veterinarian. Indeed, some foods that are dangerous for cats can cause their death in the absence of appropriate treatment!
