Are French Fries Bad for Cats?

Usually, cats don’t eat french fries but every now and then your feline friend is curious to try out what you are eating. So, the real question is whether you can give a few of it as a treat?

It is not recommended to feed them as potatoes cannot be easily digested by your cat. While not dangerous, fries include an excessive amount of sodium, carbohydrate, and fat in your cat’s stomach. Similarly, different types of potatoes have preparation limitations, making the potato a tricky human food to feed to a cat.

However, if you are still tempted to feed them then the type of french fries and other addons added to them should be checked.

First and foremost, never feed your cat raw potatoes. They contain alkaloids (the green part of potatoes) which can be poisonous to cats. Green potatoes are harmful to cats, according to both the Pet Poison Helpline and the APSCA. If you notice your cat eating green sprouts or green skin, get them checked out by a veterinarian as soon as possible.

Can Cats Eat Cooked French Fries?

The good thing is that once cooked, potatoes are no longer harmful to cats. Because of the high heat of the oil, frying is one of the cooking methods that decrease the solanine (alkaloid) content of potatoes the most. So, if your cat is going to eat cooked potato, a French fry is a better option than mashed or boiled potatoes. A plain French fry could be a better option for your cats overall.
However, Fries are only to be kept in strict moderation. They cannot be fit in a cat’s diet because not only do they lack the nutritional supplements but they also come with harmful effects if eaten too much.

Can Cats Eat French Fries With Ketchup?

Ketchup, like fries, is not the healthiest thing to give your cat. It has high salt levels, which are harmful to cats. Aside from that, most ketchup contains onion powder, which is poisonous to cats. Furthermore, ketchup is quite acidic for cats. That implies that even if your ketchup did not contain onion powder, it could still cause gastrointestinal problems in your pet.

What About Extra Flavourings?

Most sauces are highly acidic, which can upset your cat’s digestive tract. They might even puke if they try a little sauce. Some flavorings may also include substances that are poisonous to cats. Onion powder, like garlic in aioli, is a good example. Garlic and onions are both toxic to pets, according to the Pet Poison Helpline website. It’s important to remember that garlic is roughly five times more poisonous than onions.

While a very tiny amount of some of these components will have no effect on some cats, others may be more sensitive and have a more severe reaction.

The deep-fried outside of the french fry, which is high in sodium, can be tough for your cat’s body to digest and can potentially cause a choking threat. Even plain potatoes are harmful to cats. French fries and potato chips are delicious, but they are also among the most unhealthy potato products. Cats require protein to grow, and while certain carbohydrates are OK in your cat’s diet, the amount should be limited.

Heres are other reasons why you should avoid feeding fries to your cat:

Saturated Fats

Even though essential fats like Omega-3 and Omega-6 are healthy for cats. Fries are loaded with saturated fats which are unhealthy even for us, human beings. Saturated fats do not benefit your cat’s health; rather, they contribute to heart disease, weight gain, and other disorders.


Carbohydrates are not needed in your cat’s diet.

Cats’ diets only allow for a small number of carbs. Excess carbohydrate consumption can be hazardous to your pet, and because french fries are pure starch, they are especially dangerous.


A (very) little amount of salt is required in your cat’s food to maintain proper development and growth, but too much salt is extremely harmful and can poison and kill your cat.

Cat Owners should be warned that french fries contain a lot of salt. For an average 4kg cat, 42.4 mg of salt per day is enough in its diet.

Salt toxicity can result in:

  • Vomiting
  • Appetite reduction
  • Excessive drowsiness
  • Poor coordination
  • Extreme thirst / dehydration
  • Seizure, coma, and death if excessive salt is consumed

Based on this, you should limit your cat’s intake of fries to three or four per day as a one-time treat.
