Can Cats Eat Pizza? Is It Safe Or Toxic?

Can cats eat pizza

Pizza is not healthy for us, but we still consume it in a large quantity, but it’s a whole different situation when it comes to our felines.

You bought pizza at home, and your cat is already looking at you with glazed eyes for a slice of pizza, but sadly, pizza is terrible (similar to cake, ketchup, and lasagna) for the health of your felines and in any means, you shouldn’t let your felines eat it.

So, can cats eat pizza?

The short answer is no; pizza isn’t safe for felines. It contains many ingredients considered toxic for felines, such as garlic, onion, tomatoes, sauces, and other added toppings.

And cats are lactose intolerant, which means the cheese in pizza can cause tummy upset, and the meat (you might think it’s healthy but not) is loaded with spices, overcooked and rich in sodium which can cause sodium poisoning. 

However, your cat might withstand a tiny bite of pizza, and it’s best to avoid them. 

In this article, I will talk about what can happen if your cat eats pizza and how you can tackle the situation and other consequences of eating pizza.

Can Cats Eat Pizza? Not Really!

No, cats shouldn’t eat pizza.

While a tiny bite of pizza is fine, you should avoid feeding it in large quantity.

Pizza is flattened bread combined with meat, ketchup, spices, cheese and topped with vegetables like bell pepperbroccoli, corn, garlic, and onion.

Garlic and onions are the main culprits, pizza with garlic and onions is a big no, and pizza often contains a bunch of spices and hot sauces that can send your feline directly to the vet.

Moreover, the cheese in pizza is a dairy product that is again not suitable for felines; it causes stomach upset, leading to vomiting and diarrhea.

And the dough contains yeast which is bad for your cat’s digestive system, and your cat may struggle to digest the dough even if it’s cooked and never, I repeat, never feed half-cooked or raw pizza dough to felines; it can cause serious damage including, vomiting, bloating and blockage.

Thus, pizza isn’t really good for felines; there is no point in feeding something that has more potential to harm than good.

Is Pizza Safe For Cats?

Not exactly safe!

A small bite of pizza isn’t going to kill your feline friend, but it’s not recommended to feed pizza to felines as it has many ingredients that are considered poisonous for them.

Is Pizza Safe For Cats

For example, the pizza base is made with flour, yeast, salt, sugar, oil and garlic. And garlic and cats can’t be together (I mean, garlic is highly toxic to cats), and other ingredients are not healthy either.

Now comes the toppings; the usual ones are bacon, bell pepper, onion, mushroom, pepperoni, olives, and green peppers and similar to garlic, onions are equally toxic to felines.

Besides, pizza is loaded with cheese which is another concern as cats are lactose intolerant and couldn’t break down the lactose, which causes stomach upset resulting, diarrhea, vomiting, stomach pain, and bloating.

Thus, pizza isn’t safe for felines, and you should strictly keep your felines away from anything that isn’t healthy or has the potential to harm your fluffy friend.  

Pizza Has No Health Benefits For Cats

Pizza does contain vegetables, meat, and cheese, but it’s healthy for felines or you in no way.

While some may argue that pizza has many vegetables and meat, which is healthy for felines but the truth is no, it’s not healthy at all.

Now let’s look at the nutritional value of a pizza and try to understand what it gives us.

A pizza slice, usually about 100-105 grams, consists of:

  • 285 calories
  • 10-gram fat
  • 640 mg sodium
  • 36-gram carbohydrates
  • And 12-gram protein

Most of the vegetables are mixed with multiple sauces and spices to make it delicious, and the meat is overcooked and loaded with oil and other ingredients.

In fact, pizza can be extremely harmful to your cats. It contains some ingredients such as garlic, onion, tomatoes, and cheese which are toxic for felines and can lead to several mild to tremendous health issues, even death.

What About Pizza Crust, Is It Safe?

Not really!

The dough prepared with yeast, refined flour, garlic powder, oil and sugar is called pizza dough, and once it’s cooked in the oven, it becomes crispy pizza crust.

What About Pizza Crust, Is It Safe

Cats are meat-eater, and their digestive system isn’t designed to process this kind of foods.

Moreover, the pizza often dough contains toxic ingredients for your feline, such as garlic, yeast and sometimes cheese, which will likely cause stomach issues such as indigestion, bloating, and diarrhea.

And, half-cooked or uncooked pizza dough is extremely poisonous to cats; it can even take the life of your feline friend within few hours of consumption, so be careful with it.

Other harmful effects could be obesity, diabetes and cardiovascular disease due to its high calorie and fat content.

Thus, now you got an idea that why you shouldn’t let your cat eat the leftover pizza crust even when they look at you with pretty eyes.

Here is Why Pizza Is Bad For Cats

By now, you have read many times that the ingredients in pizza are toxic for felines but what exactly is toxic?

Here are the breakdowns of the ingredients that are considered poisonous for cats in moderate or extreme levels.


Yeast is the main ingredient in the preparation of the dough; it fermentation the dough, making pizza fluffy and delicious. 

But it is highly dangerous for felines as most cats are allergic to it. After consuming, they may experience vomiting, lethargy, unusual heart rate, skin irritation, stomach upset, and diarrhea.

Onion and Garlic

They are the Allium family member, and both contain sulfoxides and disulfides, which leads to hemolytic anemia in cats (highly dangerous condition), causing vomiting, breathing issue, diarrhea, fatigue, pale gums and even collapse.

Thus, if you notice any of the above symptoms in your felines, immediately take them to a professional vet to save the life of your fluffy friend. 

Loaded With Cheese 

Cheese is one of the significant aspects of pizza; without cheese, we can’t even imagine pizza, but it’s a dairy product, and most cats are lactose intolerant.

What does it mean? It means that cats cannot process and digest cheese, and the undigested cheese can lead to serious digestive issues such as excessive gas, abdominal pain, vomiting, diarrhea, constipation and dehydration in some cases.

And, during the baking processes, the cheese gets melt and releases oil which makes it even worse for the feline’s stomach.

The Crust

Cats are carnivores, solely depending on lean meat, but pizza crust is usually made with refined flour, yeast, and salt, making it worse and not appropriate for cats. 

The digestive system of a cat isn’t designed to process flour-based food such as pizza crust or bread. While cooked dough it’s not toxic, uncooked or semi-cooked pizza dough can cause health problems such as bloating, vomiting, diarrhea, digestive issues and could be fatal in some cases.

Overcooked Meat

The meat used for toppings are usually overcooked with extreme spices, sauces and mayonnaise. While raw and unflavored meat is considered good, the one in pizza isn’t.

This is because a cat’s digestive system isn’t designed to process junk, and over cooked food and high spices will likely cause indigestion. 

Besides, the meat is rich in fat which is again problematic as it will lead your feline to obesity, diabetes and cardiac diseases.

Excessive Salt

The sodium level in pizza is tremendously high than any other dish. This season behind is that salt is generously used in meat to prepare the pizza dough, sauce, seasonings, and toppings.

Cats don’t usually require sodium in their food like us, but still, they can tolerate a small amount of sodium, but more than that can cause sodium poisoning, resulting; vomiting, loss of appetite, lethargy, diarrhea, tremors, seizures, coma and even death in extreme cases.

Spices, Herbs and Sauces 

spicy tomato sauce mixed with herb, oregano, and chili flakes are the core of a pizza; pizza is not pizza without them. While the plain tomato sauce isn’t toxic, the one used in the pizza base usually contains garlic and onion, which can cause vomiting, pale gum, drooling, lethargy, gastroenteritis, anemia and death if ingested a fair amount.

Besides, the herbs and spices used to enhance the flavor are not good either; At the same time, some of them are highly toxic, while others can cause mild to severe complications such as stomach pain, diarrhea, painful bowel movements, ulcer, burning sensation, and intestinal problems.

Can Cats Eat Pepperoni Pizza?

Yes, they can, but it’s not recommended!

It’s a bad idea to feed pepperoni pizza to your felines; it can cause serious health issues.

Pepperoni is known for its taste which usually comes from the high level of salt used in the preparation. So if you feed pepperoni topped pizza, it’s likely to cause sodium poisoning.

The meat is another problems; it gets persevered to increase the longevity of the meat, which means it goes through a lot of refining process.

And the nitrated used to prevent the development of harmful bacteria and enhance the taste of the meat is relatively toxic to felines as it causes nitrate poisoning.

The commonly known symptoms of nitrate poisoning are weight loss, loss of appetite and lethargy.

Moreover, the spices used to spice up the pepperoni are relatively too high for a cat to handle, and some of them, such as garlic, black pepper, paprika, red pepper, are moderately toxic for felines. You should strictly keep your felines away from these types of foods.

And the culprit is garlic; it is the worst food you can even feed to your felines; it is considered five times more toxic than onion, while both are from the allium family.

However, the effect of garlic poisoning (i.e. vomitingdiarrheafatigueirregular heart ratebreathing issue and collapse) may not begin right away. It may take up to four days to show after the consulting of garlic which makes it more difficult to diagnose and treat as the condition may worsen with time.

Thus, you should not feed pepperoni pizza to your felines and opt for healthier alternatives such as fish, chicken, and beef. 

Summing Up!

To sum this, pizza isn’t good for felines, and you shouldn’t encourage your felines to eat it.

Most of the ingredients, which make a pizza delicious, are poisonous to cats, for example, cheese, garlic, onion, and sauces.

While a tiny bite or lick of a pizza isn’t going to kill your felines, I highly recommend you to keep aside the leftover pizza; otherwise, your cats may find some of it on the plat or dustbin. 

Pizza is the most horrible food to share with your felines, even a tiny bite of pizza can lead to severe health problems such as diarrhea, panting, fatigue, and death if not act immediately.
