As the main ingredient in lasagna is minced beef, cats are likely to enjoy eating lasagna. A small helping may not affect their health, but lasagna is not the best food for cats.

Lasagna is high in fat and calories, which can lead to weight gain and other health problems for cats. It also contains ingredients such as salt, spices, or herbs that cats shouldn’t eat.

The disadvantage of giving lasagna to your cat

There are many downsides to giving lasagna to your cat. You should carefully consider your pet’s health before serving him leftover lasagna. Your cat might not be able to digest all of the ingredients properly. Additionally, the high-fat content could lead to weight gain or other health problems.

Lasagna is also likely to include some toxic ingredients for cats, such as onions, garlic, spices, and salt. So, it is best to avoid giving your cat lasagna altogether. There are plenty of other healthy and delicious foods that you can feed your cat instead. Rather than giving your cat leftovers, choose a cat food suitable for your pet’s life stage.

Here’s why you should avoid giving your cat these ingredients that are commonly found in lasagna and other human foods:

Salt (sodium toxicity)

Salt is toxic to cats, even in small amounts, and can cause sodium poisoning. Salt can cause vomiting, diarrhea, dehydration, and even death. So, it is best to avoid giving your cat lasagna that contains salt.

Onions and garlic

Onions and garlic contain compounds called sulfoxides and disulfides, which are toxic to cats. Even small amounts can cause anemia and damage red blood cells. Symptoms of your cat suffering from anemia include fatigue, pale gums, and a general lack of energy.

Onions and garlic are part of the allium botanical family which includes other plants such as shallots, leeks, and chives that are also toxic to cats.


Some spices, such as nutmeg, cinnamon, and chili powder, can be toxic to cats. These spices can cause your cat to suffer from an upset stomach. Cats also have different types of taste buds and may not be able to taste spices and herbs in the same way we do; for this reason, they don’t need seasonings added to their food.

Tomato sauce

Cats generally aren’t used to eating tomatoes, and your pet may suffer from gastrointestinal upset if he eats too much. The acid in tomatoes can also cause tooth enamel erosion.


Cheese is high in fat and calories, which can lead to weight gain and other health problems for cats. While most cats would eat cheese, many are also lactose intolerant, so dairy products such as cheese, milk, or yogurt shouldn’t be added to their diet.


Most pasta is made from wheat flour, which is not easily digestible by cats. Additionally, the high carbohydrate content can lead to weight gain. Cats should be eating mainly meat and don’t require a diet that contains carbohydrates.

Can cats eat lasagna: Final thoughts

As you can see, there are many reasons to avoid giving your cat lasagna. If you must give your cat this dish, be sure to remove all of the harmful ingredients first. (ok, that’s probably easier said than done)

Your cat will be much better off eating a healthy, balanced diet that includes a variety of delicious and nutritious meats. It’s best to stick to cat food rather than giving your cat too many leftovers.
