Can Cats Eat Pizza? – Ingredients, Risks, and Safer Options
Can cats eat pizza? While it might seem harmless to share a slice, pizza contains ingredients that aren’t safe or healthy for cats.
Pizza night is exciting, and if you have a cat, you’ve probably noticed those curious eyes watching every bite. The smell of melted cheese and warm toppings can easily attract your furry friend, making you wonder if sharing a small piece is harmless.
Cats should not eat pizza. Pizza is generally unsafe for cats and can cause stomach upset. A tiny bite of plain cooked crust is usually harmless, but pizza is not a healthy or recommended food for cats.
Before letting your cat taste pizza, it’s important to understand how it can affect their health and whether it’s truly worth the risk.
Can Cats Have Pizza?
Cats are naturally curious, especially when strong smells like pizza fill the room. If your cat sniffs your slice or tries to sneak a bite, you might wonder if sharing is harmless. While pizza is comforting and delicious for humans, it is not made for feline bodies.
Cats are obligate carnivores, meaning their bodies are designed to get nutrients mainly from animal-based protein. Pizza is a human food built around carbs, fats, dairy, and seasonings. Even when pizza looks simple, almost every part of it works against a cat’s digestive system.
A tiny accidental nibble may not cause immediate harm, but pizza should never be offered intentionally. Making it a habit can quietly lead to digestive upset, weight gain, or toxic reactions over time.
If you’re exploring what foods are safe for your cat, you might also wonder about other human foods. For example, Can Cats Eat Garlic? is an important topic since garlic is actually toxic to cats and should always be avoided. Similarly, treats like ice cream may seem harmless, but Can Cats Eat Pistachio Ice Cream? explains why sugary and nut-based desserts aren’t a good choice for your feline friend. Always make sure to check which foods are safe before sharing anything with your cat.
Interesting Facts About Pizza
Pizza is one of the most loved foods in the world, especially in households where pets live close to their humans.
- The word “pizza” dates back to the year 997 in Italy.
- In the U.S., hundreds of slices are eaten every second.
- Pepperoni is the most popular topping.
- The smell of pizza comes from fats, cheeses, and meats—exactly the aromas that attract cats.
Cats are not craving pizza because it is good for them. They are reacting to the strong scent of animal protein and fat, which triggers natural hunting instincts. Unfortunately, attraction does not equal safety.
Nutritional Contents of Pizza
From a nutrition standpoint, pizza offers almost nothing a cat needs.
Pizza is typically high in:
- Refined carbohydrates
- Saturated fats
- Sodium (salt)
- Calories
Cats, on the other hand, need:
- High-quality animal protein
- Taurine (an essential amino acid)
- Controlled fat levels
- Very low carbohydrates
Pizza lacks taurine and contains excess calories, salt, and fat. Even a small amount can disrupt a cat’s carefully balanced diet.
A complete and balanced cat food approved by veterinary nutrition standards is far better suited to keep your cat healthy, active, and comfortable.

What Does Pizza Contain?
To understand why pizza is unsafe, let’s break down its most common ingredients and how each one affects cats.
Pizza Dough
Cooked pizza dough is mostly carbohydrates, which cats do not need. It offers no nutritional value and can contribute to weight gain.
Raw pizza dough is far more dangerous. It contains yeast that can expand in a cat’s stomach, leading to painful bloating. As yeast ferments, it produces alcohol, which can enter the bloodstream and cause alcohol poisoning. This is a veterinary emergency.
Dough also contains salt, which cats only need in very small amounts.
Tomato Sauce
Ripe tomatoes themselves are not highly toxic, but pizza sauce is rarely just tomatoes.
Most sauces include:
- Garlic
- Onions
- Salt
- Herbs and spices
Garlic and onions are toxic to cats. They can damage red blood cells and cause anemia. Even small amounts consumed repeatedly can lead to weakness, pale gums, lethargy, and digestive distress.
Cheese
Cheese smells amazing to cats, but it is one of the most misleading ingredients.
Most adult cats are lactose intolerant. Cheese can cause:
- Diarrhea
- Gas
- Vomiting
- Stomach pain
Cheese is also high in fat and calories. Regular exposure increases the risk of obesity, joint strain, and long-term health issues.
Pepperoni
Pepperoni is one of the most dangerous pizza toppings for cats.
It contains:
- Extremely high salt levels
- Garlic and spices
- Preservatives like nitrates
- Excess fat
Too much salt can lead to dehydration, tremors, vomiting, seizures, and even coma. Pepperoni also irritates a cat’s digestive system and provides calories without nutrition.

Is Pizza Safe for Cats?
In general, pizza is not safe for cats.
Most pizzas contain at least one harmful ingredient, and many contain several. Even “plain” pizza usually includes cheese, salt, and sauce that can upset a cat’s stomach.
Veterinary professionals agree that pizza offers more risk than reward. Cats do not benefit nutritionally from pizza, and repeated exposure increases health concerns.
If your cat steals a tiny bite once, it is unlikely to be life-threatening. However, pizza should never become a treat or routine snack.
Potential Health Risks
Feeding pizza to cats, even occasionally, can cause both short-term and long-term problems.
Common risks include:
- Digestive upset: vomiting, diarrhea, gas
- Toxic reactions: garlic, onion, or spice exposure
- Salt overload: dehydration, tremors, seizures
- Obesity: excess calories from cheese and dough
- Food intolerance: reactions to dairy or meats
Cats are small animals. Ingredients that seem harmless to humans can overwhelm their systems very quickly.
Guidelines for Feeding Pizza to Cats
The safest guideline is simple: don’t feed pizza to cats.
However, if your cat accidentally eats a small piece:
- Remove access to more food
- Watch for vomiting, diarrhea, or lethargy
- Contact your vet if symptoms appear
If you want to share a food experience with your cat, consider safer alternatives:
- Cooked plain chicken or turkey
- Small pieces of cooked fish (no seasoning)
- Scrambled or boiled eggs
- Vet-approved cat treats
Some owners choose to make a “cat-friendly pizza” using safe ingredients like cooked meat and vegetables without salt, garlic, or cheese. This should always be an occasional enrichment activity, not a meal replacement.
Treats should make up no more than 10% of a cat’s daily calories.
Talk To Your Vet
Every cat is unique. Age, weight, health conditions, and food sensitivities all matter.
Before offering any human food, including pizza alternatives, it’s best to talk with your veterinarian. A vet can:
- Confirm what foods are safe
- Help manage food sensitivities
- Create a balanced nutrition plan
Veterinary advice is especially important if your cat has kidney disease, obesity, digestive disorders, or allergies.

Pepperoni is very bad for cats. It is high in salt, fat, and spices and often contains garlic. Eating pepperoni can cause vomiting, dehydration, or salt poisoning, so cats should never eat it.

Dogs should not eat pizza either. Pizza is high in fat, salt, and seasonings that can upset a dog’s stomach. Ingredients like garlic and onions can be harmful, making pizza a poor choice for dogs.
Can Kittens Eat Pizza Crust
Kittens should never eat pizza crust. Their stomachs are very sensitive, and crust offers no nutrition. Even small amounts can cause diarrhea or stomach pain and may affect their healthy growth.
Can Cats Eat Bread
Cats can eat bread in moderation, but it’s essential to consider a few factors before sharing your slice. While bread isn’t toxic to felines, it’s a carbohydrate-rich food that offers little nutritional value for them.
Can Cats Eat Burgers
While the idea of sharing a juicy burger with your feline companion might seem tempting, it’s essential to tread carefully. Cats are obligate carnivores, meaning their diet primarily consists of meat. However, the rich, fatty ingredients in a burger, particularly the potential for seasoning and additives, can be problematic for your cat.
Can Stray Cats Eat Pizza
The allure of pizza is undeniable, even for our feline friends. While it may be tempting to share a slice with a stray cat, it’s essential to consider the ingredients. Most pizzas are loaded with cheese, sauces, and toppings, many of which can be detrimental to a cat’s health.
