Can Cats Eat Pizza – Some Notes For Pet Health

Can cats eat pizza? – I know you’ve always wondered this. Your favorite feline has always wanted some pizza with jalapeno peppers, but you’re not sure if it’s safe for them to eat. Is there cheese that they can’t eat? Is there tomato sauce? What about the crust!

Can Cats Eat Pizza

Cats can eat pizza crust, but they cannot eat a whole pizza. The pizza crust is not bad for cats to eat, but it is not a food that should be fed to them regularly.

Cats get most of their nutrients from meat and fish, so the crust is likely to be lacking in many essential vitamins and minerals.

Cats are carnivores. They have evolved to eat meat and fish, as well as some plants and fruits. While cats have been domesticated for thousands of years, they still retain many of their natural instincts.

These instincts tell them that they need to hunt for their food and consume it raw, which is why dry pet food is a better choice than canned cat food or wet food.

Cats do not always chew their food properly when they eat it off a plate or out of their bowl when they are hungry — this can cause digestive problems because their teeth are not designed for this kind of chewing action.

While pizza crust may be safe for your cat in moderation, it’s important not to overdo it because there are no nutritional benefits in it at all! And remember that your cat may try to steal some pizza slices off your plate too if you leave them out on the counter while cooking (especially if he smells cheese).

Is Pizza Safe For Cats?

It’s one of the most popular foods in the world and many people love it. But does that mean it’s safe for cats to eat pizza?

We’ve highlighted numerous reasons why pizza is bad for cats. And most of these reasons come down to the kind of ingredients used.

Cats are carnivores, which means their bodies are designed to digest meat. But some people think that because cats have teeth similar to humans, they can eat anything we can eat. However, that isn’t true.

Most pizzas are made with cheese or tomato sauce as their main ingredients. These can be toxic if consumed by cats.

Tomatoes contain an alkaloid called atropine, which is poisonous to animals but not humans. If your cat eats a large amount of tomato sauce or canned tomatoes, he could suffer from vomiting and diarrhea. If he eats enough, it could cause an upset stomach or even kill him within hours.

Cheese contains lactose, which can make your cat sick if he eats too much of it — especially if he has an intolerance for lactose like many humans do!

Healthier Options For Cats

If your cat is a picky eater and you feel like giving them some pizza, there are healthier options for cats to eat.

Cats need a diet that is high in protein and fat. This is because they are carnivores and their bodies can’t digest carbohydrates well.

So what are some healthy options for your cat?


Tuna is high in protein and fat and contains omega-3 fatty acids which are good for your cat’s skin and coat. It can also help with eye health by helping to keep the eyes moist. Make sure you do not give your cat canned tuna as it contains too much mercury for them to consume safely.

Try feeding them fresh tuna instead or look at other types of fish such as salmon or cod which are also rich in omega-3 fatty acids.


Chicken breast is another great source of protein for cats but make sure it’s free-range or organic to reduce the number of hormones they consume as these can be harmful to cats if consumed in large amounts.

You should also avoid chicken liver as it has high levels of vitamin A which can cause liver damage if given too often or in large quantities.

Why Is Pizza Crust Discouraged For Cats?

While it may seem like a good idea to give your cat pizza, the crust is not a good choice for your feline friend. The pizza crust is made with wheat flour, which is not a food that cats can digest well.

Wheat is a common allergen in cats. It can cause an allergic reaction or inflammation of the gastrointestinal tract that may lead to vomiting and diarrhea.

In addition, wheat contains gluten which can lead to anemia in cats because they lack an enzyme necessary to break down this protein found in grains.

So, why is pizza crust discouraged for cats?

The answer lies in how well cats process carbohydrates compared to humans and dogs. Cats lack the enzymes needed to break down carbohydrates found in most plant foods such as wheat and rice.

Most of their energy comes from protein and fat sources such as meat, organs, eggs, and dairy products (if tolerated). Their digestive system cannot handle complex carbohydrates well because they lack amylase which digests starch into glucose (sugar).

This means that when we feed our cats carbohydrate-rich foods like pizza crusts, they do not get digested efficiently by their bodies resulting in digestive issues.

Some popular pizza toppings cats can eat:

Here are some common pizza toppings that cats can eat:

  • Pepperoni
  • Sausage
  • Ham
  • Mushrooms
  • Olives
  • Tomatoes (cooked)
  • Cheese (if it isn’t hard)
  • Pizza Toppings Cats Should Avoid

While most of their favorite foods are safe for your cat to eat, there are some things you should never feed your feline friend. These include:

Onions, Garlic and Chives

Garlic and onion, chives are associated with Heinz body anemia, a debilitating disease that reduces the ability of a cat’s red blood cells to transport oxygen throughout its system. And when the cat’s internal organs and tissues do not receive adequate oxygen supply, their functions are significantly reduced.

Immediate symptoms of Heinz body anemia include generalized fatigue, paleness of the mouth and gums, intense fever, discolored skin, and labored breathing. Heinz’s body anemia is fatal.

Some Types Of Cheese

Blue cheese and feta cheese contain mold that can be toxic for your cat. Also avoid mozzarella cheese, as it may cause digestive issues such as vomiting or diarrhea if eaten by your cat.

What Happens If Cats Eat Pizza?

The question of whether or not cats can eat pizza is a very common one, especially in the United States. While it may seem harmless, there are actually some very serious health risks involved with feeding your cat pizza.

Pizza contains a lot of salt, which can cause dehydration in cats, as well as high levels of saturated fat, which can lead to kidney disease in felines. In addition, cats are lactose intolerant, so they cannot digest cow’s milk products and cheese. Ingestion of these foods can lead to diarrhea and vomiting.

It’s best not to feed your cat any human food at all! However, if you have a picky eater who only eats pizza and nothing else, try giving him a small piece (about one slice) once or twice a week. Make sure that the pizza is plain cheese pizza without any other toppings (including pepperoni).

How Much Pizza Can A Cat Eat?

Pizza isn’t a regular part of a cat’s diet — and that’s why it can be dangerous.

Cats are carnivores, so they require meat in their diets to stay healthy. If you’re going to feed your cat pizza as a treat, make sure it’s not an everyday occurrence.

If your cat eats too much pizza, he could develop nutritional deficiencies or possibly even pancreatitis (painful inflammation of the pancreas). Pancreatitis can be fatal if not treated quickly.

Cats are sensitive to high-fat food and should stick to their normal diet of kibble or canned food that contains about 10 percent fat per weight (12 percent is considered ideal).

Your veterinarian may recommend restricting your cat’s intake of fatty foods like pizza if he has been diagnosed with diabetes mellitus.

What Kind Of Pizza Can Cats Eat?

The safest pizzas for cats are those that don’t contain meat toppings. Some people make their own pizza at home using vegetarian ingredients, so if you’re interested in feeding your cat homemade pizza, this is a good option to try out.

Cats need a diet that consists mostly of meat protein, so they can eat small amounts of cheese and other dairy products in moderation.

However, these foods should not be overused or substituted with grains or starches as they do not provide enough nutrition for your pet.

Some commercial brands of frozen or refrigerated pizza may be safe for your cat too because they don’t contain meat toppings. You’ll want to check the label carefully before purchasing one of these products so you know exactly what’s inside them!

Is Pepperoni Harmful To Cats?

Pepperoni is a delicious, spicy Italian sausage made from ground pork and beef. It is a popular topping for pizza, but is pepperoni safe for cats?

Pepperoni does not have many of the nutrients that cats need to live a healthy life. It also contains nitrates, which are sometimes used as preservatives in processed meats like pepperoni.

If your cat eats too much pepperoni or other processed meats, they can develop anemia because they do not contain enough iron and B vitamins. If your cat only eats processed meats like pepperoni, they will likely become anemic.

If your cat eats a small number of pepperoni occasionally there should be no negative health effects. However, you should never feed your cat human food unless it has been approved by a veterinarian first!

What Can Cats Drink?

Cats can drink water. Water is good for them, but it should be fresh and clean. Don’t give your cat tap water unless it has been boiled for at least 10 minutes and then cooled. That will kill any bacteria in the water that could sicken your cat.

Cats also like to drink from running faucets, so you might want to keep the bathroom door closed when you’re taking a bath or shower.

If your cat doesn’t seem interested in drinking water, you can try adding a little tuna juice to her bowl of water or mixing some canned food into her water bowl.


To answer the question “Can cats eat pizza?” it is the pepperoni that makes cats sick. So, if you really want to feed pizza to your cat, bake her a dough ball with some cheese or make her a fish pie. The best pizzas are the ones that are customized for your pet.
