Can Cats Eat pizza?

The short answer is no, cats should not eat pizza. While pizza may not necessarily be harmful to cats in small quantities, it is not a suitable or healthy part of a feline diet. Cats are obligate carnivores, which means that they require a diet primarily composed of meat in order to obtain the necessary nutrients to support their health and well-being.

Importance of Feline Nutrition

Proper nutrition is essential for a cat's overall health. Feeding a balanced diet helps maintain their energy levels, coat condition, and supports their immune system.

Cats as Obligate Carnivores

Cats are obligate carnivores, meaning they need meat to survive. They rely on meat to provide essential nutrients such as taurine, which cannot be obtained from plant-based foods.

Human Food vs. Feline Diet

While it might be tempting to share food with your cat, most human foods are not suitable for them. Cats have specific dietary needs that can only be met by a balanced, species-appropriate diet.

The Ingredients of Pizza

Pizza is comprised of various ingredients that may not be suitable for feline consumption.

Dough (Flour and Yeast)

Pizza dough is primarily made from flour and yeast. Both of these ingredients have little nutritional benefit for cats and can pose risks, such as gastrointestinal issues, if consumed in large quantities.


Cheese is a common topping on pizza, but it is not recommended for cats. Lactose intolerance is common in adult cats, and consuming dairy products can cause digestive issues.

Tomato Sauce

Tomato sauce is typically acidic and can lead to stomach irritation in cats. Some types of tomato sauce may also contain onion and garlic, which can be toxic to cats.

Pizza Toppings

Many pizza toppings are unsuitable for cats, such as onion, garlic, and certain spices. Some may be safe in small quantities, like plain cooked meat or some vegetables, but cats should not rely on these toppings as part of their regular diet.

Potential Risks of Feeding Pizza to Cats

Feeding pizza to cats can lead to various health issues.

Gastrointestinal Issues

The ingredients in pizza, such as cheese or tomato sauce, can cause digestive problems and vomiting in cats.

Weight Gain and Obesity

Pizza can be high in calories, fat, and salt, which can contribute to weight gain, obesity, and related health problems if consumed regularly.

Sodium and Fat Content

High levels of sodium can put a strain on a cat's kidneys, potentially leading to kidney disease. A high-fat diet can also contribute to pancreatitis in cats.

Toxic Ingredients

Ingredients such as onion, garlic, and certain spices can be toxic to cats and cause serious health problems if ingested.

Safe and Unsafe Pizza Toppings

Cats should not consume most pizza toppings, but some may be safe in small quantities.

Safe Toppings

  • Plain Cooked Meat
  • Vegetables (excluding onions and garlic)

Unsafe Toppings

  • Onion and Garlic
  • Chives and Leeks
  • Spices and Seasonings

Alternatives to Pizza for Cats

Cats should be fed a balanced, species-appropriate diet.

Balanced Cat Foods

Commercial cat foods are designed to meet the nutritional requirements of cats. Look for high-quality options that list a meat source as the first ingredient.

Homemade Cat Treats

You can make homemade treats for your cat using appropriate, safe ingredients like cooked meat or fish.

Feeding Guidelines for Cats

Feeding guidelines vary based on your cat's age, size, and activity level. Consult your veterinarian for personalized feeding recommendations.

Tips for Keeping Your Cat Away from Pizza

To prevent your cat from consuming pizza, follow these tips:

  • Feed your cat before enjoying your own meal.
